Description

A kind of integration asphalt concrete pavement Slice by slice cutting recycling machine

Technical field

The invention patent relates to a kind of integrated asphalt concrete pavement Slice by slice cutting equipment, this equipment is able to achieve pitch The multidirectional Slice by slice cutting in concrete road surface and loading can be recycled simultaneously, to make full use of the RAP material of recycling to prepare high property The Recycled Asphalt Pavement of energy.

Background technique

At year ends 2013, statistics display Chinese cement concrete road surface is mainly used for township, in village's low-grade highway, 10.4 ten thousand In km express highway pavement, cement concrete pavement only has 3452.8km, proportion only 0.19%, asphalt concrete pavement institute Accounting example is 99.81%, and cement concrete pavement is compared with the mileage quantity of asphalt concrete pavement, almost negligible to disregard.By In asphalt concrete pavement is convenient with working drawing review with respect to other road surfaces such as cement concrete pavements, road-ability is good, prolongs Long Life of Tyre saves the advantages such as fuel oil, quick open to traffic, public to year ends 2017 national total mileage of highway 477.35 ten thousand In middle level Four and ratings above highway mileage up to 433.86 ten thousand kilometers, account for total mileage of highway 90.9%, nearly all use pitch coagulation Soil surface, the update of original cement, sand-gravel surface, which overlays, also gradually uses Asphalt Concrete Overlay.Urban road is also in this way, mesh Preceding nearly all urban road all uses asphalt concrete pavement.However, the design service life of asphalt concrete pavement is shorter, 8 ~ 15 years, with the continuous development of logistics, the ratio of Heavy Traffic was increasing, and traffic volume growth rate is higher and higher, pitch Concrete road surface early damage is also increasingly severe, and actual use just needs maintenance and renovation for 7 ~ 8 years, and some even runs 2 ~ 3 years just Start the destruction such as crack, pit slot occur.The highway built up successively after the nineties entered it is big or middle repair the phase, hereafter, often Year there are about 12% bituminous pavement needs to overhaul, and Bituminous concrete surface discarding amount is up to annual 2200000 tons, and this number be with What annual about 15% speed increased, after 10 years, the big or middle old asphalt mixture for repairing generation of bituminous pavement is up to thousands of Ten thousand tons.It digs, the asphalt bulk deposition of milling is in both sides of the road and other fixed venues, or useless as garbage loading embeading It abandons, not only pollutes environment in this way, but also waste valuable resource.One side pitch is the heavier hard-degraded substance of smell, will be caused Surrounding enviroment seriously pollute；On the other hand new building stones are largely exploited, will lead to forest cover reduction, soil erosion etc. is serious broken Bad ecological environment, and the significant wastage of resource is caused, as many as 1,500,000,000 yuan of fee of material can be saved every year if through regeneration.Cause This, the exploitation of research, the popularization and relative special-purpose equipment of asphalt concrete regenerating technology, to reducing the construction costs, protecting ecology Environment and the resource-conserving to our countries, environmentally friendly amphitypy society and sustainable development highway construction have pole Big meaning.

Applied of Asphalt Pavement Recycle Technique is comparative maturity in the application of developed country and popularizes.The U.S. is that earliest research uses The country of asphalt pavement regeneration and reutilization technology, so far from 1976, road surface waste regeneration utilization rate is more than 70%.West Europe Country also attaches great importance to this technology, the waste asphalt pavement material regeneration rate of European Asphalt road surface association (EAPA) each member state Reach 100%.The collection and storage work of old pavement material are all organized in the almost all of cities and towns of Finland, and the world is through being combined within 1997 It knits and detailed investigation has been carried out to 14 national ground surface material regeneration situations, delivered " road engineering regeneration war Slightly " white paper points out that the regeneration rate of old bitumen pavement material is 75% ~ 100% in book.Again according to international clean energy resource and environmental protection Raw administration's statistics, American-European bituminous pavement recycling have reached 80% or more, and Holland, Spain have had reached 100%.According to another report, External bituminous pavement can be accomplished repeatedly to recycle.

For China's bituminous pavement recycling and reusing rate there are also larger gap compared with American-European countries, pitch regeneration in China's is big at present Sizable application is also in the starting stage, in " Recycling Old Asphalt Mixture using " project research that the nineteen eighty-three Ministry of Construction assigns, Light oil appropriate is added in old residual-oil pavement to soften it, mixing and stirring for mixture is carried out using the conventional equipment suitably reequiped, and In Suzhou, Wuhan, Tianjin, four, Nanjing city making, more than 30,000 square metres of Experiment Road, regenerated road surface is proved through observation It is comprehensive to be not less than conventional Hot-mix Bituminous Concrete Pavement using quality.And since the late 1980s, along with China The Large scale construction of high-grade highway, new highway road surface almost no longer consider that, using waste and old ground surface material, pitch regeneration is withdrawn to Backseat, correlative study popularization are substantially at dead state.Until in recent years, with growth, the budget of national road demand The reduction of fund, and to the needs of safe and efficient and cost-effective roadnet, the demand that existing road repairs It increases substantially.National Environmental Protection Agency and expert also appeal that " waste asphalt pavement material is containing the noxious materials such as sweet smell, naphthalene, degradation speed Slowly, contaminated soil and water source；These obsolete material main components are pitch and basalt, are all non-renewable resources, not good Good utilisation is sorry blue mountains and green waters ".As bituminous pavement reconstruction, the feature of environmental protection repaired, economy technology-asphalt road plane materiel In the work schedule of the material regenerative use technology person that refers to highway work again, become the hot issue of highway scientific research.One A little scientific research institutions and colleges and universities start to carry out the research and extension of hot in-place recycling.For example, 1998, Department of Communications, Handan City introduces Witt, Germany root company WR2500 regenerating device is changed using one section highway of the situ regeneration technology to Hebei Province for the first time Make maintenance.2003, introduce in wide Buddhist express highway pavement overhaul U.S. ASTEC company twin-roll pitch regeneration stirring apparatus into The regeneration of row bituminous pavement, this is the highway projects of the first large-scale application plant-mix heat recycle technology in China, mesh Preceding behaviour in service is good.But compared with developed countries, the asphalt surface hot reproduction technology in China not yet forms complete material Appraisement system, mixing proportion design method, construction technology, again generating apparatus and quality control standard, therefore still need to for relevant issues exhibition Open further further investigation.It is domestic at present to the research of hot in-plant reclaimed old material be concentrated mainly on to old material moisture content, gradation, The research of bitumen content, the performance for recycling pitch etc., few pairs of former ground surface materials carry out layering recycling and layering research And obtain the work of valuable conclusion.Chang An University Deng Xiaoqing in its paper by route hierarch milling sample, for Each layer sample carries out bitumen recovery respectively and has carried out the test of index of correlation, obtains bituminous pavement with its different aging of depth Degree has significant difference, and surface layer aging is more serious, and with the increase of depth, aging will be more slowly.Xu Ke " is returned in his paper The Zhejiang Province's Hangzhoupro Shen Jiahu highway is had chosen in influence of debit's formula to recycling material of waste asphalt variability " and Hangzhou-Zhejiang high speed is public The recycling material of waste asphalt acquired when the heavy resurfacing of two highways with typical representative in road is studied, broken material Milling material when 1-6mm acquisition is from the Hangzhoupro Shen Jiahu highway heavy resurfacing in 2012, milling not divided lane, regardless of structure sheaf； Milling material 1-6mm is the milling material in Hong Yong Freeway upper layer (3 lane), is the RAP for being layered milling.It is dripped from two kinds of RAP The testing result of green content obtains, and two groups of RAP Asphalt Contents are significantly different, wherein Hong Yong Freeway upper layer RAP milling Bitumen content in material is higher more stable, and average content reaches 4.74%, the coefficient of variation 3.1869%, and the Hangzhoupro Shen Jiahu high speed is public The RAP Asphalt Content average value on road is 3.96%, and the coefficient of variation has reached 5.5% or so, and bitumen content variability is larger, says Bright layering milling can effectively improve the variability of RAP Asphalt Content；From the bitumen aggregate ratio curve of asphalt reclamation material it can also be seen that The bitumen aggregate ratio of reclaimed materials without layered shaping will be significantly lower than the bitumen aggregate ratio of the reclaimed materials of layered shaping.As it can be seen that different structure Bitumen content in the RAP of layer is widely different, so that the performance that will lead to RAP morphs, carries out to same highway It is layered milling, also has certain help to the uniformity aspect for improving bitumen content.The testing result for performance of gathering materials in RAP is also such as This, the RAP of Hong Yong Freeway gather materials each test group the discreteness for being sieved through rate it is smaller, and the Shen of not layered milling is good The discreteness of the rate that is sieved through of gathering materials of the RAP of lake Hangzhoupro highway is obvious, thus illustrates to be layered what milling gathered materials to RAP Gradation influence is also related, and layering milling can keep the gradation grade on former road surface substantially, does not make gradation that big variation occur.Therefore, Way of recycling is very crucial to the effective use of reclaimed asphalt mixture.
