摘要
高性能沥青具有较高的黏度,能够适应交通荷载作用下路面局部变形而引起的拉应力的反复作用。文章分别对高黏沥青和改性沥青的路用性能进行试验研究,并进行现场试验段验证。结果表明,高性能沥青具有较高的抵抗水损害的能力和良好的抗车辙能力,更利于行车安全。
High-performance asphalt has high viscosity and can adapts repeated tensile stress action caused by local deformation of pavement in traffic load. In this paper, the road performance of asphalt with high viscosity and modified asphalt are tested which also verfied by field tests. The research results show that high-performance asphalt has high capacity of resistance to water damage and rutting which are beneficial to driving safety.
