Description
本發明有關再生瀝青評價用樣品評價方法及再生瀝青混合料之製造方法。 The present invention relates to a sample evaluation method for evaluating recycled asphalt and a method for manufacturing a recycled asphalt mixture.
以往，使用瀝青混合物(瀝青混合料)之道路鋪設供用5~10年左右，於發生車輪壓陷或龜裂等之損傷時，進行修繕。此時，將鋪設表面受到損傷之瀝青混合料中，切削去除深5cm左右，另外於該現場平坦均勻鋪設新製造的瀝青混合料。又，瀝青混合料係將調整為特定粒度之骨材(碎石、砂、石粉等)與特定量瀝青混合者。此處，骨材粒度及瀝青量示於鋪設設計施工指南(平成18年(2006年)版)(日本道路協會(公社))之附表-8.1.7。 In the past, roads using asphalt mixture (asphalt mixture) were paved for about 5 to 10 years, and repairs were required when damage such as wheel dents or cracks occurred. At this time, the damaged asphalt mixture on the paving surface is cut to a depth of about 5cm, and the newly manufactured asphalt mixture is laid flat and evenly on the site. In addition, asphalt mixture is a mixture of aggregates (gravel, sand, stone powder, etc.) adjusted to a specific particle size and a specific amount of asphalt. Here, the aggregate particle size and asphalt amount are shown in Appendix Table-8.1.7 of the Pavement Design and Construction Guidelines (2006 edition) (Japan Road Association (Japan)).
此處，道路鋪設之修繕時去除之瀝青混合物(供用後之瀝青混合料)並未廢棄，而經過特定手續，形成為再生瀝青混合物(再生瀝青混合料)，並作為道路鋪設用材料再利用。該供用後之瀝青混合料(再生粒料(aggregate))之再利用(鋪設再生)中，為使再生粒料中所含之已劣化瀝青之性狀回復，而決定添加軟質再生添加劑 等。該手續記載於例如鋪設再生便覽(平成22年(2010年)版)(日本道路協會(公社))之「2-5再生鋪設用材料之調配設計」。 Here, the asphalt mixture removed during road paving repairs (reused asphalt mixture) is not discarded, but is converted into a recycled asphalt mixture (recycled asphalt mixture) through specific procedures, and is reused as a road paving material. In the reuse (paving regeneration) of the used asphalt mixture (recycled aggregate (aggregate)), in order to restore the properties of the degraded asphalt contained in the recycled aggregate, it is decided to add a soft regeneration additive wait. This procedure is described in, for example, "2-5 Preparation and Design of Materials for Recycling Pavement" in the Pavement Recycling Handbook (2010 edition) (Japan Road Association (Japan)).
於近幾年之道路鋪設領域中，相較於開通新道路構築新穎鋪設，更要求適當維持、修繕既有道路。該情況下，鑒於資源有效利用之觀點及建設回收法，而推薦使用再生瀝青混合料。因此，於日後之道路鋪設領域中，期待再生瀝青混合料之性狀提高。 In the field of road paving in recent years, rather than opening new roads and constructing novel paving, it is more necessary to properly maintain and repair existing roads. In this case, the use of recycled asphalt mixture is recommended from the viewpoint of effective resource utilization and construction recycling methods. Therefore, in the field of road paving in the future, it is expected that the properties of recycled asphalt mixtures will be improved.
製造再生瀝青混合料時，為了使再生粒料中所含之已劣化硬化瀝青(舊瀝青)之性狀成為與新穎瀝青(新穎瀝青)同等性狀，而使用稱為軟化劑之鋪設再生用的再生添加劑(例如專利文獻1)。且根據情況，亦有添加新穎瀝青之情況。此處，作為上述性能，決定為使JIS K 2207所示之針入度(與黏度類似之物理性狀)成為同等。亦即瀝青混合料之調配設計(決定骨材之組合，設為特定粒度，及找出適當瀝青量)中，要求舊瀝青與再生添加劑之混合物的針入度與新穎瀝青之針入度同等。 When manufacturing recycled asphalt mixture, in order to make the properties of the deteriorated hardened asphalt (old asphalt) contained in the recycled pellets equivalent to those of new asphalt (fresh asphalt), a recycling additive called a softener is used for paving regeneration. (For example, Patent Document 1). And depending on the situation, novel asphalt may be added. Here, the above-mentioned performance is determined so that the penetration (a physical property similar to viscosity) shown in JIS K 2207 becomes equivalent. That is to say, in the mixing design of asphalt mixture (determining the combination of aggregates, setting it to a specific particle size, and finding the appropriate amount of asphalt), the penetration of the mixture of old asphalt and recycled additives is required to be the same as that of new asphalt.
[專利文獻1]日本特開2013-155345號公報 [Patent Document 1] Japanese Patent Application Publication No. 2013-155345
然而，基於滿足上述針入度之調配設計所製造之再生瀝青混合料，與全部使用新的材料(骨材及瀝青)製造之新穎瀝青混合料相比，鋪設後之耐車輪壓陷性能雖優異，但有耐龜裂性差的情況。 However, compared with novel asphalt mixtures made entirely of new materials (aggregate and asphalt), the recycled asphalt mixture produced based on the blending design that satisfies the above-mentioned penetration has excellent wheel crush resistance after laying. , but may have poor crack resistance.
又，確認隨再生瀝青混合料所用之再生添加劑之品項亦即內容物之差異而耐車輪壓陷性能不同。該性能差異舉例一要因為舊瀝青與再生添加劑之組合。相對於此，關於再生添加劑之黏度等之物理性狀之規定雖已作出上述之鋪設再生便覽，但有關化學性狀之規定除引火點以外並未規定。亦即，對於舊瀝青與再生添加劑混合形成之再生瀝青，並未確立定量的評價方法，而無法抑制包含再生瀝青之再生瀝青混合料之品質偏差。藉由此等情況，要求可形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料的評價方法及再生瀝青混合料之製造方法。 Furthermore, it was confirmed that the wheel crush resistance performance differs depending on the content of the recycled additives used in the recycled asphalt mixture. One example of this performance difference is due to the combination of old asphalt and recycled additives. In contrast, although the above-mentioned pavement regeneration guide has stipulated the physical properties such as the viscosity of the regeneration additive, there are no regulations regarding the chemical properties other than the ignition point. That is, a quantitative evaluation method has not been established for recycled asphalt formed by mixing old asphalt and recycled additives, and it is impossible to suppress quality deviations of recycled asphalt mixtures containing recycled asphalt. Under these circumstances, there is a demand for an evaluation method for a recycled asphalt mixture that has quality equal to or higher than that of a novel asphalt mixture, and a manufacturing method for a recycled asphalt mixture.
因此本發明係鑒於上述問題點而提出者，其目的在於提供可形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料的再生瀝青評價用樣品評價方法及再生瀝青混合料之製造方法。 Therefore, the present invention was proposed in view of the above-mentioned problems, and its object is to provide a sample evaluation method for recycled asphalt evaluation and a manufacturing method of the recycled asphalt mixture that can form a recycled asphalt mixture with quality equal to or higher than that of the novel asphalt mixture.

以下，針對應用本發明之再生瀝青評價用樣品之評價方法的實施形態之一例詳細說明。 Hereinafter, an example of an embodiment of the evaluation method applying the sample for evaluation of recycled asphalt of the present invention will be described in detail.
本發明人著眼於再生粒料所含之舊瀝青與鋪設再生用之再生添加劑混合，形成再生瀝青評價用樣品之狀態，亦即舊瀝青與再生添加劑之相互作用，而發現評價組合良否之方法。本發明人係形成使不同種類之舊瀝青及再生添加劑之組合予以混合之複數再生瀝青評價用樣品，確認各再生評價用樣品之混合狀態之結果，確認有顯示均一混合狀態之組合，及顯示不均一混合狀態而生成污泥之組合。又，對應於再生瀝青評價用樣品所含之污泥量，確 認表示壓裂功量之差。因此，發現基於再生瀝青評價用樣品所含之污泥量，可評價舊瀝青與再生添加劑之組合良否之再生瀝青評價用樣品之評價方法。藉此，基於評價進行調配設計，可形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料。 The present inventors focused on the state in which old asphalt contained in recycled pellets is mixed with a recycling additive for paving regeneration to form a sample for evaluation of recycled asphalt, that is, the interaction between the old asphalt and the recycling additive, and discovered a method to evaluate the quality of the combination. The inventors of the present invention formed a plurality of recycled asphalt evaluation samples by mixing different combinations of old asphalt and regeneration additives, and confirmed the results of the mixing state of each regeneration evaluation sample. A combination of sludge produced in a uniform mixing state. Furthermore, corresponding to the amount of sludge contained in the sample for evaluation of recycled asphalt, it is confirmed The recognition indicates the difference in fracturing power. Therefore, a method for evaluating samples for reclaimed asphalt evaluation that can evaluate the quality of a combination of old asphalt and a reclaimed additive was discovered based on the amount of sludge contained in the sample for reclaimed asphalt evaluation. Through this, blending and design based on evaluation can produce a recycled asphalt mixture with quality equal to or better than that of novel asphalt mixtures.
以下，針對本實施形態之再生瀝青評價用樣品之評價方法所用之材料加以說明。圖1(a)係顯示再生粒料1之示意剖面圖，圖1(b)係顯示鋪設再生用之再生添加劑21之示意剖面圖，圖1(c)係顯示再生瀝青混合材2之示意剖面圖 Hereinafter, materials used in the evaluation method of the recycled asphalt evaluation sample according to this embodiment will be described. Figure 1(a) is a schematic cross-sectional view showing the recycled granular material 1, Figure 1(b) is a schematic cross-sectional view showing the regeneration additive 21 for laying and recycling, and Figure 1(c) is a schematic cross-section showing the recycled asphalt mixture material 2. Figure
如圖1(a)所示，再生粒料1包含骨材11與舊瀝青12。再生粒料1係供用後者，係道路鋪設修繕時經去除者。再生粒料1由於主要係供用於戶外，故暴露於水、紫外線、氧等中。藉此，舊瀝青12與新穎瀝青(製油所製造之原餾瀝青(straight asphalt))相比，顯示硬且脆之傾向。 As shown in FIG. 1(a) , the recycled aggregate 1 includes aggregate 11 and old asphalt 12 . The recycled aggregates 1 are used for the latter and are removed during road paving and repair. Since the recycled pellets 1 are mainly used outdoors, they are exposed to water, ultraviolet rays, oxygen, etc. Therefore, the old asphalt 12 tends to be hard and brittle compared with the new asphalt (straight asphalt produced by oil refining).
因此，再利用再生粒料1時，如圖1(b)所示，添加再生添加劑21。藉由混合再生添加劑21與舊瀝青12，如圖1(c)所示，形成再生瀝青22。藉此，形成包含再生瀝青22與骨材11之再生瀝青混合材2。又，根據需要亦可混合新穎瀝青。 Therefore, when reusing the recycled pellets 1, as shown in Fig. 1(b), a regeneration additive 21 is added. By mixing the regeneration additive 21 and the old asphalt 12, as shown in Fig. 1(c), the regeneration asphalt 22 is formed. Thereby, the recycled asphalt mixture 2 including the recycled asphalt 22 and the aggregate 11 is formed. In addition, novel asphalt can be mixed as needed.
再生添加劑21至少包含例如溶劑萃取油及潤滑油基油等之與新穎瀝青相比之黏度較低之烴之哪一者。再生添加劑21除了可含有例如碳數3~22的飽和脂肪酸或不飽和脂肪酸或該等之混合物或二聚物等以外，亦可含有例 如聚合物等。 The regeneration additive 21 contains at least one of hydrocarbons having a lower viscosity than the novel asphalt, such as a solvent extraction oil or a lubricant base oil. The regeneration additive 21 may contain, for example, saturated fatty acids or unsaturated fatty acids with 3 to 22 carbon atoms, or mixtures or dimers of these fatty acids. Such as polymers, etc.
溶劑萃取油含較多芳香族分，主要用以補足已劣化舊瀝青12之芳香族分而添加之作為軟化劑作用之成分。溶劑萃取油係自原油製造潤滑油時之溶劑萃取過程所生成之萃取油，係富含芳香族分及環烷烴之油狀物質(參考「至可成為石油製品」，圖6-1“一般潤滑油製造步驟”，石油聯盟發行，昭和46年11月，p.99及「新石油辭典」，石油學會編，1982年，p.304)。 Solvent-extracted oil contains more aromatic components and is mainly used to supplement the aromatic components of degraded old asphalt 12 and is added as a softener. Solvent-extracted oil is the extracted oil generated during the solvent extraction process when lubricating oil is produced from crude oil. It is an oily substance rich in aromatic components and naphthenes (refer to "To the point where it can become a petroleum product", Figure 6-1 "General Lubrication" "Oil Manufacturing Process", published by the Petroleum Federation, November 1982, p. 99 and "New Petroleum Dictionary", edited by the Petroleum Society, 1982, p. 304).
潤滑油基油主要是用以使因供用而硬化之舊瀝青12軟化所添加。作為潤滑油基油之生成方法係使用如下方法，例如使用丙烷脫瀝青法自減壓蒸餾殘油萃取脫瀝青油，使用溶劑萃取法自脫瀝青油萃取純化油、使用溶劑脫蠟法自純化油萃取脫蠟油，使用氫化純化法自脫蠟油生成潤滑油基油之方法。 The lubricating oil base oil is mainly added to soften the old asphalt 12 that has been hardened due to use. The lubricating oil base oil is produced by the following methods, for example, the propane deasphalting method is used to extract deasphalted oil from the vacuum distillation residual oil, the solvent extraction method is used to extract purified oil from the deasphalted oil, and the solvent dewaxing method is used to purify the oil. A method of extracting dewaxed oil and using hydrogenation purification to generate lubricating oil base oil from the dewaxed oil.
新穎瀝青係以調整再生混合料中之瀝青量為目的而添加。作為新穎瀝青係使用例如原餾瀝青(參考JIS K 2207)、吹製瀝青(參考JIS K 2207)、半吹製瀝青(參考「瀝青鋪設綱要」，公益社團法人日本道路協會發行，平成9年1月13日，p.51，表-3.3.4)、溶劑脫瀝青之瀝青(參考「新石油辭典」，公益社團法人石油學會編，1982年，p.308)、聚合物改質瀝青(參考鋪設設計施工指南(平成18年版)，公益社團法人日本道路協會發行，平成18年2月24日，p.223，附表-8.1.11)等之瀝青或該等之混合物。 Novel asphalt is added for the purpose of adjusting the amount of asphalt in the recycled mixture. Examples of novel asphalt systems used include raw asphalt (refer to JIS K 2207), blown asphalt (refer to JIS K 2207), and semi-blown asphalt (refer to "Asphalt Paving Guidelines", published by the Japan Road Association, 2019-1 July 13, p.51, Table -3.3.4), solvent deasphalted asphalt (refer to "New Petroleum Dictionary", compiled by the Petroleum Institute, 1982, p.308), polymer modified asphalt (refer to Paving Design and Construction Guidelines (2018 Edition), published by the Japan Road Association, February 24, 2018, p.223, Appendix -8.1.11) and other asphalt or mixtures thereof.
本實施形態中再生瀝青評價用樣品之評價方 法係使用使上述再生添加劑21與舊瀝青12混合之再生瀝青評價用樣品。藉由使用再生瀝青評價用樣品，可評價舊瀝青12與再生添加劑21是否均一混合。又，再生瀝青評價用樣品形成為例如比再生瀝青22更易評價之狀態。 Method for evaluating samples for evaluating recycled asphalt in this embodiment The method uses a sample for evaluation of recycled asphalt in which the above-mentioned recycled additive 21 and old asphalt 12 are mixed. By using the recycled asphalt evaluation sample, it can be evaluated whether the old asphalt 12 and the recycled additive 21 are uniformly mixed. Furthermore, the recycled asphalt evaluation sample is in a state that is easier to evaluate than the recycled asphalt 22, for example.
圖2(a)及圖2(b)係再生瀝青評價用樣品之光學顯微鏡圖像及再生瀝青評價用樣品之過濾後的過濾片上的堆積物圖像。藉由圖2(a)及圖2(b)所觀察之再生瀝青評價用樣品係舊瀝青12與再生添加劑21之組合不同。 2(a) and 2(b) are optical microscope images of the sample for reclaimed asphalt evaluation and images of deposits on the filter sheet after filtering the sample for reclaimed asphalt evaluation. The sample for recycled asphalt evaluation observed in Figures 2(a) and 2(b) has a different combination of old asphalt 12 and regeneration additive 21.
再生瀝青評價用樣品有藉由舊瀝青12與再生添加劑21之組合而包含污泥之情況。圖2(a)所示之再生瀝青評價用樣品，由於舊瀝青12與再生添加劑21均一混合，故幾乎未觀測到污泥，於過濾後之過濾片上亦未確認到堆積物。相對於此，圖2(b)所示之再生瀝青評價用樣品，由於舊瀝青12與再生添加劑21未均一混合，故顯著觀測到污泥(圖中黑色部分)，於過濾後之過濾片上亦確認到堆積物。 The sample for regenerated asphalt evaluation may contain sludge due to the combination of the old asphalt 12 and the regeneration additive 21. In the sample for evaluation of recycled asphalt shown in Figure 2(a), since the old asphalt 12 and the regeneration additive 21 were uniformly mixed, almost no sludge was observed, and no deposits were confirmed on the filter after filtration. In contrast, in the sample for evaluation of recycled asphalt shown in Figure 2(b), since the old asphalt 12 and the regeneration additive 21 are not uniformly mixed, sludge (black part in the figure) is clearly observed, and also on the filter after filtration. Accumulation was confirmed.
發明人發現藉由測定再生瀝青評價用樣品中所含之污泥含量，可評價舊瀝青12與再生添加劑21是否均一混合。 The inventor found that by measuring the sludge content contained in the sample for evaluation of recycled asphalt, it is possible to evaluate whether the old asphalt 12 and the regeneration additive 21 are uniformly mixed.
其次，針對本實施形態之再生瀝青評價用樣品之評價方法順序之一例詳細說明。圖3係顯示本實施形態之再生瀝青評價用樣品之評價方法的一例的流程圖。 Next, an example of the evaluation method sequence of the recycled asphalt evaluation sample according to this embodiment will be described in detail. FIG. 3 is a flow chart showing an example of the evaluation method of the sample for evaluation of recycled asphalt according to this embodiment.
首先，形成再生瀝青評價用樣品(步驟S110)。再生瀝青評價用樣品係使舊瀝青12與再生添加劑21混合而形成。此時，依據鋪設調查‧試驗法便覽G029，自再生粒料1萃取回收舊瀝青12而使用。 First, a sample for recycled asphalt evaluation is formed (step S110). The sample for evaluation of recycled asphalt was formed by mixing the old asphalt 12 and the regeneration additive 21 . At this time, the old asphalt 12 is extracted and recovered from the recycled aggregate 1 according to Paving Survey and Test Method Manual G029 and used.
其次，測定再生瀝青評價用樣品中所含之污泥(步驟S120)。 Next, the sludge contained in the sample for evaluation of recycled asphalt is measured (step S120).
污泥含量，例如如圖2(b)之照片，基於使再生瀝青評價用樣品利用過濾器過濾之結果予以測定。此時藉由測量過濾器上堆積之污泥量，可定量測定污泥含量。 The sludge content is measured based on the result of filtering the sample for evaluation of recycled asphalt with a filter, for example, as shown in the photograph of Fig. 2(b). At this time, by measuring the amount of sludge accumulated on the filter, the sludge content can be quantitatively determined.
其次，基於測定污泥之結果，評價舊瀝青12與再生添加劑21之組合良否(步驟S130)。亦即，基於污泥之測定結果，可判斷舊瀝青12與再生添加劑21是否均一混合，可評價組合良否。 Next, based on the results of measuring the sludge, the quality of the combination of the old asphalt 12 and the regeneration additive 21 is evaluated (step S130). That is, based on the measurement results of the sludge, it can be determined whether the old asphalt 12 and the regeneration additive 21 are uniformly mixed, and whether the combination is good or not can be evaluated.
例如測定污泥含量時，污泥含量較少時，相較於含量較多時，可判定舊瀝青12與再生添加劑21均一混合，可評價為組合良好。步驟S130中，例如污泥含量為2.00重量%以下時，評價為舊瀝青12與再生添加劑21之組合良好。 For example, when measuring the sludge content, when the sludge content is small, it can be determined that the old asphalt 12 and the regeneration additive 21 are uniformly mixed compared to when the sludge content is large, and the combination can be evaluated as good. In step S130, for example, when the sludge content is 2.00% by weight or less, it is evaluated that the combination of the old asphalt 12 and the regeneration additive 21 is good.
藉此，結束本發明之再生瀝青評價用樣品評價方法之順序。又，本評價方法中，亦可形成舊瀝青12與 再生添加劑21之組合不同的複數再生瀝青評價用樣品，基於各再生瀝青評價用樣品中所含之污泥測定結果，評價相對良否。 This concludes the procedure of the sample evaluation method for evaluating recycled asphalt according to the present invention. In addition, in this evaluation method, old asphalt 12 and A plurality of recycled asphalt evaluation samples with different combinations of the regeneration additives 21 were evaluated for relative quality based on the measurement results of the sludge contained in each recycled asphalt evaluation sample.
依據本實施形態之再生瀝青評價用樣品評價方法，基於測定污泥含量之結果，評價舊瀝青12與再生添加劑21之組合良否。因此，藉由污泥含量，可定量地實施組合之良否評價。藉此，基於評價進行調配設計，可形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料2。 According to the sample evaluation method for evaluating regenerated asphalt in this embodiment, based on the result of measuring the sludge content, the quality of the combination of the old asphalt 12 and the regeneration additive 21 is evaluated. Therefore, the quality evaluation of the combination can be quantitatively performed based on the sludge content. In this way, the blending design based on the evaluation can form a recycled asphalt mixture 2 with quality equal to or better than that of the novel asphalt mixture.
又，上述評價基準，可對應於使用再生瀝青混合料2之環境，而任意設定。例如，除了污泥含量為2.00重量%以下以外，為1.83重量%以下、或0.11重量%以下等時，評價為舊瀝青12與再生添加劑21之組合良好，而可選擇形成耐龜裂性能特別優異之再生瀝青混合料2。 In addition, the above-mentioned evaluation criteria can be set arbitrarily according to the environment in which the recycled asphalt mixture 2 is used. For example, when the sludge content is 2.00% by weight or less, 1.83% by weight or less, or 0.11% by weight or less, it is evaluated that the combination of the old asphalt 12 and the regeneration additive 21 is good, and the formation of particularly excellent crack resistance can be selected. Recycled asphalt mixture 2.
其次，針對應用本發明之再生瀝青混合料2之製造方法之實施形態的一例詳細說明。圖4係顯示本實施形態之再生瀝青混合材2之製造方法的一例的流程圖。又，關於步驟S110~步驟S130，與上述再生瀝青評價用樣品評價方法同樣內容相關，省略適當說明。 Next, an example of an embodiment of the manufacturing method of the recycled asphalt mixture 2 to which the present invention is applied will be described in detail. FIG. 4 is a flow chart showing an example of the manufacturing method of the recycled asphalt mixture 2 according to this embodiment. In addition, steps S110 to S130 are related to the same content as the above-mentioned sample evaluation method for evaluating recycled asphalt, and appropriate explanations are omitted.
步驟S110中，將再生瀝青混合料2之製造中所用之預定舊瀝青12之一部分與再生添加劑21混合形成再生瀝青評價用樣品。因此，舊瀝青12之消耗以少量即足 夠，故例如組合之評價差時，可最小限度地抑制材料損失。 In step S110, a part of the predetermined old asphalt 12 used in the production of the recycled asphalt mixture 2 is mixed with the regeneration additive 21 to form a sample for evaluation of the recycled asphalt. Therefore, a small amount of old asphalt 12 is enough to consume Therefore, for example, when the evaluation of the combination is poor, material loss can be minimized.
步驟S130中，評價為舊瀝青12與再生添加劑21之組合良好時，基於該評價結果，混合骨材11、舊瀝青12、再生添加劑21(步驟S140)。又，例如評價為舊瀝青12與再生添加劑21之組合不良時，變更舊瀝青12或再生添加劑21之種類，再次實施步驟S110~步驟S130。此處，為了調整混合料中之瀝青量，亦可混合新穎瀝青。 In step S130, if it is evaluated that the combination of the old asphalt 12 and the regeneration additive 21 is good, based on the evaluation result, the aggregate 11, the old asphalt 12, and the regeneration additive 21 are mixed (step S140). For example, if it is evaluated that the combination of the old asphalt 12 and the regeneration additive 21 is defective, the type of the old asphalt 12 or the regeneration additive 21 is changed, and steps S110 to S130 are performed again. Here, in order to adjust the amount of asphalt in the mixture, novel asphalt can also be mixed.
藉此，形成再生瀝青混合料2，結束本實施形態之再生瀝青混合料2之製造方法。 Thereby, the recycled asphalt mixture 2 is formed, and the manufacturing method of the recycled asphalt mixture 2 of this embodiment is completed.
依據本實施形態之再生瀝青混合料2之製造方法，基於測定污泥含量之結果，評價舊瀝青12與再生添加劑21之組合良否，基於評價，混合骨材11、舊瀝青12、再生添加劑21。亦即，基於組合良否評價可製造再生瀝青混合料2。因此，製造再生瀝青混合材2之前，可實施混合良否評價。藉此，可容易地形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料2。又，可實現作業時間之縮短、或作業成本及再生瀝青混合料2之材料成本之削減。 According to the manufacturing method of the recycled asphalt mixture 2 of this embodiment, based on the result of measuring the sludge content, the quality of the combination of the old asphalt 12 and the regeneration additive 21 is evaluated, and based on the evaluation, the aggregate 11, the old asphalt 12, and the regeneration additive 21 are mixed. That is, the recycled asphalt mixture 2 can be produced based on the combination quality evaluation. Therefore, before manufacturing the recycled asphalt mixture material 2, the mixing quality can be evaluated. Thereby, it is possible to easily form the recycled asphalt mixture 2 having a quality equal to or higher than that of the novel asphalt mixture. In addition, the operation time can be shortened, and the operation cost and the material cost of the recycled asphalt mixture 2 can be reduced.
以下，針對應用本發明之再生瀝青評價用樣 品評價方法，列舉實施例及比較例具體加以說明。 The following is a sample for evaluating the recycled asphalt using the present invention. The product evaluation method will be described in detail with examples and comparative examples.
本實施例中，使用各不同之再生添加劑形成再生瀝青評價用樣品(評價樣品)，測定各評價樣品中所含之污泥含量。隨後，使用各評價樣品與同樣之再生添加劑形成再生瀝青混合料之樣品(混合料評價樣品)，實施混合料評價樣品之壓裂試驗。接著，確認壓裂試驗結果與污泥含量之關連性。 In this example, different regeneration additives were used to form samples (evaluation samples) for evaluation of regenerated asphalt, and the sludge content contained in each evaluation sample was measured. Subsequently, each evaluation sample and the same regeneration additive were used to form a sample of a recycled asphalt mixture (mixture evaluation sample), and a fracturing test was performed on the mixture evaluation sample. Next, the correlation between the fracturing test results and the sludge content was confirmed.
首先，依據鋪設調查‧試驗法便覽G029，自再生粒料萃取回收舊瀝青，將其與再生添加劑混合，形成評價樣品。評價樣品係作成表1所示之7種(實施例1~4、比較例1~3)。各評價樣品分別使用主成分不同之再生添加劑，實施例1~4使用芳香族系成分為主成分之再生添加劑，比較例1~3使用飽和分系成分為主成分之再生添加劑。作為再生用添加劑之性狀，動黏度係在JIS K2283「原油及石油製品-動黏度試驗方法及黏度指數計算方法」之條件下測 定。且，再生用添加劑之各成分(飽和分、芳香族分、樹脂分及瀝青烯)之含量係於JPI-5S-70-10「利用TLC/FID法之瀝青組成分析試驗方法」之條件下測定。 First, in accordance with the paving survey and test method manual G029, old asphalt is extracted and recovered from recycled pellets, and mixed with recycled additives to form an evaluation sample. Seven types of evaluation samples (Examples 1 to 4, Comparative Examples 1 to 3) shown in Table 1 were prepared. Each evaluation sample uses a regeneration additive with a different main component. Examples 1 to 4 use a regeneration additive with an aromatic component as the main component, and Comparative Examples 1 to 3 use a regeneration additive with a saturated component as the main component. As a property of the additive for regeneration, the dynamic viscosity is measured under the conditions of JIS K2283 "Crude oil and petroleum products-Kinematic viscosity test method and viscosity index calculation method" Certainly. In addition, the content of each component of the regeneration additive (saturated content, aromatic content, resin content and asphaltene) was measured under the conditions of JPI-5S-70-10 "Test method for asphalt composition analysis by TLC/FID method" .
以舊瀝青量與再生添加劑量之比以重量比計設為1比9而形成各評價樣品。形成各評價樣品時，再生添加劑之溫度設為常溫，瀝青混合料之溫度設為130℃，以藥杓攪拌1分鐘後，於130℃保持1小時。 Each evaluation sample was formed with the ratio of the amount of old asphalt to the amount of regeneration additive being 1:9 in terms of weight ratio. When forming each evaluation sample, the temperature of the regeneration additive was set to normal temperature, and the temperature of the asphalt mixture was set to 130°C. After stirring with a medicine spoon for 1 minute, the mixture was maintained at 130°C for 1 hour.
其次，使用過濾方法過濾各評價樣品，測定污泥含量。過濾方法係參考ISO10307-2(石油產物-殘餘燃料油中總污泥)而實施。過濾方法係使用圖5所示之過濾器100。作為過濾方法，係於過濾器100之漏斗101內設置過濾片102，保持評價樣品。以該狀態加熱評價樣品及透過減壓器104減壓，而使通過過濾片102之評價樣品之一部分堆積於抽吸瓶103內，污泥殘留於過濾片102上。藉由該方法，使用過濾前之評價樣品之量與過濾後殘留於過濾片102上之污泥量，測定污泥含量。 Next, each evaluation sample was filtered using the filtration method, and the sludge content was measured. The filtration method is implemented with reference to ISO10307-2 (Petroleum Products - Total Sludge in Residual Fuel Oil). The filtering method uses the filter 100 shown in Figure 5. As a filtration method, a filter piece 102 is installed in the funnel 101 of the filter 100 to hold the evaluation sample. In this state, the evaluation sample is heated and the pressure is reduced by the pressure reducer 104, so that part of the evaluation sample that has passed through the filter 102 is accumulated in the suction bottle 103, and sludge remains on the filter 102. By this method, the sludge content is measured using the amount of the evaluation sample before filtration and the amount of sludge remaining on the filter sheet 102 after filtration.
本實施例中，使用上述規格所例示之玻璃纖維過濾片(網眼1.6μm)作為過濾片102。本實施例中，將過濾片102、漏斗101及評價樣品於130℃加熱，使用減壓器104以抽吸瓶103之壓力約為0.05MPa之條件實施過濾方法。 In this embodiment, a glass fiber filter (1.6 μm mesh) exemplified by the above specifications is used as the filter 102 . In this embodiment, the filter piece 102, the funnel 101 and the evaluation sample are heated at 130°C, and the pressure reducer 104 is used to implement the filtration method under the condition that the pressure of the suction bottle 103 is about 0.05MPa.
實施上述過濾方法之結果以表1之污泥量表示。實施例1~4中，污泥量為2.00重量%以下。相對於此，比較例1~3中，污泥量分別為超過2.00重量%之值。 The results of implementing the above filtration method are represented by the sludge volume in Table 1. In Examples 1 to 4, the sludge amount is 2.00% by weight or less. On the other hand, in Comparative Examples 1 to 3, the sludge amount exceeded 2.00% by weight.
其次，使用與實施例1~4、比較例1~3同樣之再生添加劑，形成混合料評價樣品。混合料評價樣品係以表2所示條件混合供用後之再生粒料、再生添加劑、新穎瀝青後，經過模擬筒倉儲存試驗而形成。模擬筒倉儲存試驗係使用圖6所示之模擬筒倉器200而實施。使用之材料中，再生粒料係使用滿足鋪設再生便覽(平成22年版)公益社團法人日本道路協會發行，p.11，表2.3.1中記載之瀝青水泥再生粒料品質之舊瀝青含量4.79%，舊瀝青之針入度20。再生添加劑使用同樣滿足鋪設再生便覽(平成22年版)p.14，表2.3.4中記載之再生添加劑之標準性狀者。新瀝青係使用滿足JIS K 2207中記載之原餾瀝青60~80之品質的新瀝青針入度66、新瀝青之軟化點47.5℃者。模擬筒倉儲存試驗係於通常瀝青混合料製造後使一定期間儲存之狀態再現的試驗。藉由實施該試驗，可形成接近於道路鋪設時之條件的 混合料評價樣品。 Next, the same regeneration additive as in Examples 1 to 4 and Comparative Examples 1 to 3 was used to form a mixture evaluation sample. The mixture evaluation sample is formed by mixing the recycled pellets, recycled additives, and novel asphalt for use under the conditions shown in Table 2, and then undergoing a simulated silo storage test. The simulated silo storage test was implemented using the simulated silo device 200 shown in Figure 6 . Among the materials used, the recycled aggregates are used with an old asphalt content of 4.79% that satisfies the quality of asphalt cement recycled aggregates listed in Table 2.3.1 of the Japan Road Association, p. , the penetration of old asphalt is 20. Use regeneration additives that also meet the standard properties of regeneration additives described in Table 2.3.4 of p.14 of the Pavement Regeneration Handbook (2012 Edition). The new asphalt uses new asphalt with a penetration of 66 and a softening point of 47.5°C that meets the raw asphalt quality of 60 to 80 recorded in JIS K 2207. The simulated silo storage test is a test that reproduces the state of storage for a certain period of time after ordinary asphalt mixture is manufactured. By carrying out this test, it is possible to create conditions close to those at the time of road paving. Mixture evaluation samples.
模擬筒倉器200之儲存部201係儲存混合料評價樣品。儲存於儲存部201之混合料評價樣品係通過對支持部及錘203之載荷重(圖6之箭頭)由密封部202均一加壓。 The storage part 201 of the simulated silo 200 stores mixed material evaluation samples. The mixed material evaluation sample stored in the storage part 201 is uniformly pressurized by the sealing part 202 by applying a heavy load to the support part and the hammer 203 (arrow in FIG. 6 ).
本實施例中，以混合料評價樣品量為4930g，儲存溫度為160℃，儲存時間為6小時，載荷重為60kg，載荷壓力為0.22kg/cm2，儲存部201之直徑為17cm之條件，實施模擬筒倉儲存試驗。 In this example, the mixed material evaluation sample amount is 4930g, the storage temperature is 160°C, the storage time is 6 hours, the load weight is 60kg, the load pressure is 0.22kg/cm 2 , and the diameter of the storage part 201 is 17cm. Implement simulated silo storage tests.
模擬筒倉儲存試驗後之混合料評價樣品，依據「鋪設調查‧試驗法便覽B001馬歇爾(Marshall)安定度試驗方法(日本道路協會)」，製作馬歇爾供試體。又，製作條件係將夯實溫度設為120℃，進行兩面75次夯實。 The mixture evaluation sample after the simulated silo storage test was used to prepare a Marshall test body based on the "Layout Survey and Test Method Handbook B001 Marshall Stability Test Method (Japan Road Association)". In addition, the production conditions were to set the tamping temperature to 120°C and to perform tamping on both sides 75 times.
其次，對於上述各混合料評價樣品之馬歇爾供試體實施壓裂試驗。壓裂試驗係依據「鋪設再生便覽(平成22年度版，附錄-2瀝青水泥再生粒料之壓力係數求得方法(日本道路協會))」實施。壓裂試驗係使用圖7(a)所示之壓裂試驗機300實施。壓裂試驗係於壓裂試驗機300之下支撐部301與上支撐部302之間，夾入圓柱狀之混合料評價樣品310，自上支撐部302側加壓(箭頭之壓力P)。試驗機係使用島津製作所製之萬能力學試驗機AG-5000D，以載荷速度為50mm/min，試驗溫度為20℃，供試體養生條件為20℃×5小時之條件實施。如圖7(b)所示，將使混合料評價樣品310斷裂時之最大荷重與位移量之乘積除以2所得 之值作為壓裂功量而導出。又，位移量之起點設為測定荷重成為147N之點，位移量之終點設為顯示最大荷重之點。 Next, a fracturing test was performed on the Marshall specimens of the above-mentioned mixture evaluation samples. The fracturing test was carried out in accordance with the "Pavement Recycling Handbook (2012 Edition, Appendix-2 Method for Determining the Pressure Coefficient of Asphalt Cement Recycled Granules (Japan Road Association)"). The fracturing test is performed using the fracturing testing machine 300 shown in Figure 7(a). The fracturing test is performed by sandwiching the cylindrical mixture evaluation sample 310 between the lower supporting part 301 and the upper supporting part 302 of the fracturing testing machine 300, and applying pressure from the upper supporting part 302 side (pressure P indicated by the arrow). The testing machine is a universal mechanical testing machine AG-5000D manufactured by Shimadzu Corporation. The load speed is 50mm/min, the test temperature is 20°C, and the test body health condition is 20°C × 5 hours. As shown in Figure 7(b), the product of the maximum load and displacement when the mixed material evaluation sample 310 breaks is divided by 2. The value of is derived as the fracturing work amount. In addition, the starting point of the displacement amount is set to the point where the measured load becomes 147N, and the end point of the displacement amount is set to the point where the maximum load is displayed.
此處，壓裂功量較大之混合料評價樣品310，可評價為於施加拉伸應力時，可吸收直至破壞之功較大。此處，作為使用再生瀝青混合料之鋪設的課題，與新穎瀝青混合料相比，有耐龜裂性能較差之情況。此認為係因為對於施加於再生瀝青混合料之拉伸應力，再生瀝青混合料不斷抵抗該應力而斷裂所發生。藉此，壓裂試驗中混合料評價樣品310之壓裂功量較大時，以與混合料評價樣品310相等之條件製造之再生瀝青混合料認為可抵抗較大之拉伸應力，可評價為耐龜裂性能優異。 Here, the mixture evaluation sample 310 with a large amount of fracturing power can be evaluated as having a large amount of work that can be absorbed until destruction when tensile stress is applied. Here, as a problem of paving using recycled asphalt mixture, crack resistance may be poor compared with novel asphalt mixture. This is thought to occur because the recycled asphalt mixture continues to resist the tensile stress applied to the recycled asphalt mixture and breaks. Therefore, when the fracturing work of the mixture evaluation sample 310 is large in the fracturing test, the recycled asphalt mixture produced under the same conditions as the mixture evaluation sample 310 is considered to be able to withstand greater tensile stress, and can be evaluated as Excellent crack resistance.
實施上述壓裂試驗之結果示於表1之壓裂功量及圖8。實施例1~4之壓裂功量均為14.0N‧m以上。相對於此，比較例1~3之壓裂功量均未達14.0N‧m。 The results of carrying out the above fracturing test are shown in the fracturing power in Table 1 and Figure 8. The fracturing power of Examples 1 to 4 are all above 14.0N·m. In contrast, the fracturing power of Comparative Examples 1 to 3 did not reach 14.0N‧m.
此處，參考例1係使用新穎原餾瀝青與新骨材之新穎瀝青混合料，壓裂功量為14.0N‧m。又，參考例2係使用實際供用之耐龜裂性能高的改質瀝青的新穎瀝青混合料，壓裂功量為19.8N‧m。由參考例1及參考例2，可知壓裂功量越大，耐龜裂性能越大。 Here, Reference Example 1 is a novel asphalt mixture using novel raw asphalt and new aggregates, and the fracturing power is 14.0N‧m. In addition, Reference Example 2 is a novel asphalt mixture using modified asphalt with high crack resistance that is actually available, and the fracturing power is 19.8N‧m. From Reference Example 1 and Reference Example 2, it can be seen that the greater the fracturing power, the greater the crack resistance.
基於上述，由於實施例1~4與比較例1~3相比，壓裂功量較大，故確認可評價為耐龜裂性能優異。又，實施例1~4係參考例1之使用新穎原餾瀝青之新穎瀝青混合料之壓裂功量以上(圖8之箭頭)，確認可評價為相比於新穎瀝青混合料，耐龜裂性能優異。 Based on the above, since Examples 1 to 4 have larger fracturing power than Comparative Examples 1 to 3, it was confirmed that they can be evaluated as having excellent crack resistance. In addition, Examples 1 to 4 are more than the fracturing power of the novel asphalt mixture using novel virgin asphalt in Reference Example 1 (arrow in Figure 8), and it is confirmed that it can be evaluated as having better crack resistance than the novel asphalt mixture. Excellent performance.
由上述，實施例1~4之污泥含量為2.00重量%以下。相對於此，比較例1~3之污泥含量為超過2.00重量%之值。且，實施例1~4之壓裂功量確認為使用新穎原餾瀝青之參考例1及比較例1~3之壓裂功量以上。由此，確認評價樣品所含之污泥量與基於評價樣品之混合量評價樣品中之壓裂功量的大小有相關。換言之，再生瀝青所含之污泥量較少時，舊瀝青與再生添加劑係均一混合，於包含該再生瀝青之再生瀝青混合料中，顯示耐龜裂性能優異之傾向。 From the above, the sludge content in Examples 1 to 4 is 2.00% by weight or less. On the other hand, the sludge content of Comparative Examples 1 to 3 was a value exceeding 2.00% by weight. Furthermore, the fracturing power of Examples 1 to 4 was confirmed to be greater than that of Reference Example 1 and Comparative Examples 1 to 3 using novel raw asphalt. From this, it was confirmed that the amount of sludge contained in the evaluation sample is related to the magnitude of the fracturing power in the evaluation sample based on the mixing amount of the evaluation sample. In other words, when the recycled asphalt contains a small amount of sludge, the old asphalt and the recycled additives are uniformly mixed, and the recycled asphalt mixture containing the recycled asphalt tends to have excellent crack resistance.
亦即，本實施例中，基於測定污泥含量之結果，確認可評價舊瀝青與再生添加劑之組合良否。因此，藉由污泥狀態，可定量地實施組合良否評價。藉此，基於評價而調配設計，可形成具有與新穎瀝青混合料同等以上品質之再生瀝青混合料。 That is, in this example, based on the results of measuring the sludge content, it was confirmed that the quality of the combination of old asphalt and regeneration additives can be evaluated. Therefore, combination quality evaluation can be quantitatively performed based on the sludge state. In this way, the blending and design based on evaluation can form a recycled asphalt mixture with quality equal to or better than that of novel asphalt mixture.
