Description
本發明是有關一種冷拌瀝青的組合物及其用於快速修復道路的方法。 The invention relates to a cold-mixed asphalt composition and a method for quickly repairing roads.
瀝青混凝土路面是目前世界各國高等級公路的主要路面的鋪裝類型。瀝青混凝土路面具有表面平整、無接縫、振動小、雜訊低、行車舒適、養護維修方便等優點。目前採用的道路修復施工大都使用熱拌瀝青混凝土，但在使用熱拌瀝青混凝土的過程中需經過繁瑣的加熱工序並藉由大型機具的輔助，且施工後不能立即開放交通，例如道路封閉時間約3至4小時。 Asphalt concrete pavement is currently the main pavement type of high-grade highways in countries around the world. Asphalt concrete pavement has the advantages of smooth surface, no joints, low vibration, low noise, comfortable driving and convenient maintenance and maintenance. At present, most of the road repair construction uses hot mix asphalt concrete, but in the process of using hot mix asphalt concrete, it needs to go through a cumbersome heating process and be assisted by large machinery, and the traffic cannot be opened immediately after construction, such as road closure time is about 3 to 4 hours.
冷拌瀝青(又稱常溫乳化瀝青)係使用瀝青焦油加入界面活性劑使其乳化，使用時混摻入高鹼性之石粉或水泥粉，使得懸浮於乳化液中之瀝青微粒破乳化，繼而還原成瀝青焦油黏結鋪面。雖然，冷拌瀝青施工便利，但是其主要缺點在於其凝固緩慢，約需1~3天才適合輾壓。 Cold-mixed asphalt (also known as normal-temperature emulsified asphalt) is emulsified by adding asphalt tar and surfactants. When used, it is mixed with highly alkaline stone powder or cement powder, so that the asphalt particles suspended in the emulsion are broken and emulsified, and then reduced Asphalt tar sticks to the pavement. Although the construction of cold-mixed asphalt is convenient, its main disadvantage is its slow solidification, which takes about 1 to 3 days to be suitable for rolling.

具體的說，本發明係使用純度含量90%以上的菱鎂礦石在經過攝氏溫度1000℃至1800℃，例如1100℃、1200℃、1300℃、1400℃、1500℃、1600℃或1700℃，的高溫燒結後，而形成重燒氧化鎂，且重燒氧化鎂的平均粒徑(或稱粒徑分布D50)為120~250um，例如可為130um、140um、150um、160um、170um、180um、190um、200um、210um、220um、230um或240um。 Specifically, the present invention uses magnesite ore with a purity content of more than 90% at a temperature of 1000°C to 1800°C, such as 1100°C, 1200°C, 1300°C, 1400°C, 1500°C, 1600°C, or 1700°C. After high temperature sintering, re-fired magnesia is formed, and the average particle size (or particle size distribution D50) of re-fired magnesia is 120-250um, such as 130um, 140um, 150um, 160um, 170um, 180um, 190um, 200um, 210um, 220um, 230um or 240um.
具體的說，本發明係使用純度含量90%以上的菱鎂礦石在經過攝氏溫度400℃至900℃之間，例如450℃、500℃、550℃、600℃、650℃、700℃、750℃、800℃或850℃，的高溫燒結後，而形成輕燒氧化鎂，且輕燒氧化鎂的平均粒徑(或稱粒徑分布D50)為30~250um，例 如可為35um、40um、45um、50um、55um、60um、65um、70um、75um、80um、90um、100um、150um或200um。更詳細的說，由於輕燒氧化鎂的活性比重燒氧化鎂的活性更大，因此，具有足夠重量份的輕燒氧化鎂可以加快瀝青組成物之間的聚合反應速率。 Specifically, the present invention uses magnesite ore with a purity content of more than 90% at a temperature between 400 °C and 900 °C, such as 450 °C, 500 °C, 550 °C, 600 °C, 650 °C, 700 °C, and 750 °C. , 800 ℃ or 850 ℃ high temperature sintering, and form lightly burned magnesium oxide, and the average particle size (or particle size distribution D50) of lightly burned magnesium oxide is 30~250um, for example Such as 35um, 40um, 45um, 50um, 55um, 60um, 65um, 70um, 75um, 80um, 90um, 100um, 150um or 200um. In more detail, since the activity of light burnt magnesium oxide is greater than that of heavy burnt magnesium oxide, a sufficient amount of light burnt magnesium oxide can accelerate the polymerization reaction rate between the asphalt compositions.
均勻混合磷酸鹽6~9重量份和純水4~6重量份，以形成第二劑。在多個實施方式中，磷酸鹽包含磷酸二氫鉀、磷酸二氫銨、磷酸二氫鈉、磷酸氫二鈉及磷酸鉀水溶液，但不以此為限。值得注意的是，磷酸鹽的純度含量需大於95%以上，優選地須大於98%。在多個實例中，當磷酸鹽的粒徑越小，則磷酸鹽溶於純水的速率越快，因此優選地磷酸鹽的平均粒徑可為1um至150um，例如3um、5um、7um、10um、13um、15um、17um、20um、23um、25um、27um、30um、40um、50um、60um、70um、80um、90um、100um、110um、120um、130um或140um。 6-9 parts by weight of phosphate and 4-6 parts by weight of pure water are uniformly mixed to form a second agent. In various embodiments, the phosphate includes potassium dihydrogen phosphate, ammonium dihydrogen phosphate, sodium dihydrogen phosphate, disodium hydrogen phosphate, and potassium phosphate aqueous solution, but not limited thereto. It is worth noting that the purity content of phosphate must be greater than 95%, preferably greater than 98%. In many examples, the smaller the particle size of the phosphate, the faster the phosphate dissolves in pure water, so preferably the average particle size of the phosphate may be 1um to 150um, such as 3um, 5um, 7um, 10um , 13um, 15um, 17um, 20um, 23um, 25um, 27um, 30um, 40um, 50um, 60um, 70um, 80um, 90um, 100um, 110um, 120um, 130um or 140um.
於常溫下，快速拌合第一劑、第二劑和乳化瀝青6~20重量份1至3分鐘，以形成冷拌瀝青漿料。須說明的是，冷拌瀝青漿料為具有黏性及流動性的液體，因此在後續道路修補的澆注過程中只須將其抹平而無須經過壓實的處理。本發明所使用的乳化瀝青係符合中華民國國家標準之CNS1304，K5016的規範，且乳化瀝青與重燒氧化鎂和輕燒氧化鎂的結合性能良好，不但能改變瀝青材料的剛度，還可以增強與瀝青路面的黏結性能。在多個實施方式中，乳化 瀝青(又稱水柏油)包含陽離子乳化瀝青或陰離子乳化瀝青。在多個實例中，陽離子乳化瀝青包含特快凝一號(rapid setting，RS-1)陽離子乳化瀝青、特快凝二號(rapid setting，RS-2)陽離子乳化瀝青、快凝一號(medium setting，MS-1)陽離子乳化瀝青、快凝二號(medium setting，MS-2)陽離子乳化瀝青、慢凝一號(slow setting，SS-1)陽離子乳化瀝青、慢凝二號(slow setting，SS-2)陽離子乳化瀝青以及CRS-1。陰離子乳化瀝青包含特快凝一號(rapid setting，RS-1)陰離子乳化瀝青、特快凝二號(rapid setting，RS-2)陰離子乳化瀝青、快凝一號(medium setting，MS-1)陰離子乳化瀝青、快凝二號(medium setting，MS-2)陰離子乳化瀝青、慢凝一號(slow setting，SS-1)陰離子乳化瀝青以及慢凝二號(slow setting，SS-2)陰離子乳化瀝青。 At room temperature, quickly mix the first agent, second agent and emulsified asphalt from 6 to 20 parts by weight for 1 to 3 minutes to form a cold-mixed asphalt slurry. It should be noted that cold-mixed asphalt slurry is a viscous and fluid liquid, so in the pouring process of subsequent road repairs, it only needs to be smoothed out without compaction treatment. The emulsified asphalt used in the present invention conforms to the specifications of CNS1304 and K5016 of the National Standards of the Republic of China, and the combination of emulsified asphalt with heavy burned magnesium oxide and light burned magnesium oxide is good, which can not only change the rigidity of the asphalt material, but also enhance The bonding performance of asphalt pavement. In various embodiments, emulsification Asphalt (also known as water asphalt) contains cationic emulsified asphalt or anionic emulsified asphalt. In various examples, the cationic emulsified asphalt includes cationic emulsified asphalt (Rapid setting, RS-1), cationic emulsified asphalt (rapid setting, RS-2), medium setting, MS-1) cationic emulsified asphalt, medium setting (MS-2) cationic emulsified asphalt, slow setting (SS-1) cationic emulsified asphalt, slow setting (SS-low setting) 2) Cationic emulsified asphalt and CRS-1.

在其他多個實施方式中，在形成冷拌瀝青漿料的過程中，也可以包含添加0~5重量份的碎石，以提高道路修補區域與車輛之間的摩擦力。在其他某些實施方式中，在形成冷拌瀝青漿料的過程中，還可以添加0~0.1重量份的引氣劑，以去除冷拌瀝青漿料在快速拌合時所產生的氣泡。此外，在其他某些實施方式中，在形成冷拌瀝青漿料的過程中，還可以添加0~2重量份的水溶性聚氨酯，使得後續冷拌瀝青漿料於凝固後除了具有防水抗滲的效果之外，更可以提高其使用的耐久性。另外，在其他某些實施方式中，在形成冷拌瀝青漿料的過程中，還可以添加0~2重量份的橡膠粉， 以改變冷拌瀝青漿料的顏色使其與原路面顏色相仿，並使修補後的道路其兼具剛性與柔性的效果。 In other embodiments, in the process of forming the cold-mixed asphalt slurry, 0 to 5 parts by weight of crushed stone may also be added to increase the friction between the road repair area and the vehicle. In some other embodiments, in the process of forming the cold-mixed asphalt slurry, 0 to 0.1 parts by weight of an air-entraining agent may also be added to remove air bubbles generated during the rapid mixing of the cold-mixed asphalt slurry. In addition, in some other embodiments, in the process of forming the cold-mixed asphalt slurry, 0 to 2 parts by weight of water-soluble polyurethane may also be added, so that the subsequent cold-mixed asphalt slurry will be waterproof and impermeable after solidification. In addition to the effect, the durability of its use can be improved.

值得一提的是，由於硼砂會大幅降低冷拌瀝青漿料在聚合反應中的速率，進而造成冷拌瀝青漿料凝固的時間拉長，因此本發明之快速修復道路的方法不包含添加硼砂。 It is worth mentioning that, since borax will greatly reduce the rate of the cold-mixed asphalt slurry in the polymerization reaction, which will cause the cold-mixed asphalt slurry to solidify for a longer period of time, the method of the present invention for rapid repair of roads does not include the addition of borax.
接著，將冷拌瀝青漿料澆注在道路修補區域並整平。靜置此冷拌瀝青漿料至少10分鐘，使其在道路修補區域中凝固。在多個實施例中，冷拌瀝青漿料靜置的時間可為10分鐘至3小時，例如10分鐘至15分鐘、15分鐘至20分鐘、15分鐘至30分鐘、15分鐘至45分鐘、15分鐘至1小時或15分鐘至2小時。於靜置後即可開放通車。 Next, the cold-mixed asphalt slurry is poured into the road repair area and leveled.
