Durable asphalt mixture based on high-modulus asphalt
The invention relates to a durable asphalt mixture based on a high-modulus asphalt mixture. The durable asphalt mixture comprises high-modulus asphalt and mineral aggregate, the high-modulus asphalt is 100 parts and the mineral aggregate is 5.0-6.0 parts, the mineral aggregate is composed of aggregate and mineral powder, and the aggregate and the mineral powder account for 93-98% and 2-7% of the total mass of the mineral aggregate respectively. The mixture has the following advantages: the mixture has good high temperature resistance, modulus performance, fatigue resistance and durability; when the mixture is applied to the lower surface layer of a road, the strain generated by the asphalt concrete under the action of vehicle load can be reduced, and the anti-fatigue and anti-rutting capabilities of the pavement are improved; the service life and the maintenance period of the pavement are prolonged and the economic benefit is improved.
本发明涉及一种基于高模量沥青混合料的耐久性沥青混合料。包括高模量沥青和矿料，所述矿料质量份为100份，则所述石油沥青的质量份为5.0～6.0份；所述矿料由集料和矿粉组成，分别占矿料总质量的93～98％和2～7％；发明的混合料具有如下有优点：具有较好的高温性、模量性能、抗疲劳性能和耐久性能；用在道路下面层，可减少车辆荷载作用下沥青混凝土产生的应变，提高路面的抗疲劳和抗车辙的能力；有利于延长路面使用寿命和维修周期，提高经济效益。
