Low-temperature-cracking-resistant asphalt mixture and preparation method thereof
The invention discloses a low-temperature cracking resistant asphalt mixture and a preparation method thereof, and relates to an asphalt mixture and a preparation method thereof. The invention aims to solve the problems that the low-temperature cracking resistance of the existing asphalt and modified asphalt is still not ideal enough, a large amount of asphalt and modified asphalt are required to be used in an asphalt mixture, and the cost of an asphalt pavement is increased. The low-temperature cracking resistant asphalt mixture is prepared from the following components in parts by weight: 4.5 to 5.5 parts of asphalt, 100 parts of aggregate, 0.5 to 0.6 part of SBS (Styrene Butadiene Styrene) grafted hyperbranched polyglycerol and 0.3 to 0.4 part of polyester fiber. The preparation method disclosed by the invention is simple, a small amount of SBS grafted hyperbranched polyglycerol is used, the cost is reduced, the use quality of an asphalt mixture pavement is improved, and the preparation method has a wide application prospect. According to the invention, the low-temperature cracking resistant asphalt mixture can be obtained.
一种抗低温开裂的沥青混合料及其制备方法，它涉及一种沥青混合料及其制备方法。本发明的目的是要解决现有沥青及改性沥青的抗低温开裂性能仍然不够理想，在沥青混合料中需要大量使用，提高了沥青路面的成本的问题。一种抗低温开裂的沥青混合料按重量份数计，包括4.5份～5.5份沥青、100份集料、0.5份～0.6份SBS接枝超支化聚甘油和0.3份～0.4份聚酯纤维。本发明制备方法简单，少量使用SBS接枝超支化聚甘油，降低了成本，改善了沥青混合料路面的使用品质，具有广阔的应用前景。本发明可获得一种抗低温开裂的沥青混合料。
