Epoxy asphalt mixture for high-temperature-resistant road and preparation method of epoxy asphalt mixture
The invention discloses a high-temperature-resistant epoxy asphalt mixture for a road, and the high-temperature-resistant epoxy asphalt mixture for the road is prepared from the following components in parts by mass: 0.3 to 1.7 parts of epoxy resin, 0.2 to 1.1 parts of epoxy curing component, 3.5 to 7.0 parts of SBS (Styrene Butadiene Styrene) modified asphalt, 100 to 150 parts of mineral aggregate and 0.1 to 0.4 part of fiber. According to the invention, through the designed epoxy resin and curing components, the optimized SBS modified asphalt and compound fibers, the asphalt mortar forms an epoxy, SBS and fiber triple space network structure. In addition, the customized epoxy asphalt mixture for the road is specially graded, so that the epoxy asphalt mixture still has excellent high-temperature performance under the condition of relatively low epoxy doping amount, meanwhile, early-stage strength support is provided for pavement of the epoxy asphalt mixture for the road, the curing time is shortened, and traffic can be opened when the pavement temperature is reduced to 50 DEG C or below.
本发明公开了一种耐高温路用环氧沥青混合料，路用环氧沥青混合料按质量份计，包括：0.3～1.7份环氧树脂、0.2～1.1份环氧固化组分、3.5～7.0份SBS改性沥青、100～150份矿料以及0.1～0.4份纤维。本发明通过设计的环氧树脂和固化组分，优选的SBS改性沥青、复配纤维，使得沥青胶浆形成“环氧、SBS、纤维”三重空间网络结构。加之定制路用环氧沥青混合料专属级配，保障了环氧沥青混合料在较低的环氧掺量条件下，仍然具有优异的高温性能，同时也为路用环氧沥青铺装提供前期强度支撑，缩短养生时间，实现待铺装温度降至50℃内即可开放交通。
