摘　　要：基于构造深度来评价沥青路面的抗滑性能,采用主骨料空隙体积填充法进行沥青混合料的配合比设计,研究了拌和与成型温度、碾压次数等参数对构造深度和混合料性能的影响,并室内验证SMA-5的路用性能。试验结果表明,成型温度和碾压次数均会显著影响其构造深度和高温稳定性。芯样试验发现,构造深度与压实度和碾压工艺之间存在着良好的相关性。The skid resistance property of the asphalt pavement is evaluated based on the structural depth in the paper,the coarse aggregate void filling method is introduced to carry out the mixing design of asphalt mixture,and the effect of mixing and compaction temperature,rolling times parameters on the structural depth and properties of asphalt mixture are studied.Then the road performance of SMA-5 is verified indoors.Results show that the rolling temperature and compaction times can affect the structural depth and high temperature stability significantly.Core test shows that there is a good correlation among the structural depths,compaction degree and rolling method.
