摘要
为进一步提升普通微表处混合料的路用耐久性,本文采用高黏改性乳化沥青,并结合矿料级配优化,开展了高黏改性乳化沥青稀浆混合料配合比设计,确定了各类材料的最佳配比,并进行了路用性能评价。结果表明,高黏改性乳化沥青稀浆混合料的黏聚力、6 d湿轮磨耗值和车辙变形率等指标均能满足A级微表处的技术要求,相较于普通微表处,高黏改性乳化沥青稀浆混合料早期强度形成更快,具有更高的抗磨耗损失性能,并且与原路面之间的黏结更为牢固,总体表现出更优的路用耐久性。
In order to improve the durability of ordinary micro-surfacing mixtures,this paper used high viscosity modified emulsified asphalt and combines mineral aggregate gradation optimization to design the slurry mixture with the high viscosity modified emulsified asphalt,determined the optimal mix proportion and evaluated the road performance.The results showed that the cohesion,6d wet wheel wear value,and rutting deformation rate of slurry mixture with the high viscosity modified emulsified asphalt can meet the technical requirements of Class A micro-surfacing.Compared with ordinary micro-surfacing,it has the higher early strength and wear resistance,and the stronger adhesion with the original road surface,showing overall better road durability.
