硬质沥青路面具有良好的高温性能外,还应考虑其他路用性能是否满足使用要求。本文开展了硬质沥青混合料的路用性能研究,对比分析了三种硬质沥青混合料和70#普通沥青混合料的路用性能的差异。研究结果表明,硬质沥青混合料具有优异的高温性能和水稳定性,但低温性能的表现不及70#普通沥青混合料。本文的研究成果为硬质沥青混合料在我国的推广应用提供有益参考。
Hard asphalt pavement has good high temperature performance, but also consider whether other road performance to meet the requirements. In this paper, we studied the road performance of hard asphalt mixture and compared the difference of road performance between the three kinds of hard asphalt mixture and 70 # common asphalt mixture. The results show that the hard asphalt mixture has excellent high temperature performance and water stability, but the performance of low temperature performance is less than 70 # ordinary asphalt mixture. The research results of this paper provide a useful reference for the popularization and application of hard asphalt mixture in our country.
