沥青混凝土高温性能对比分析

Comparative analysis of high temperature performance of asphalt concrete

车辙作为沥青路面的典型病害,是沥青混凝土高温稳定性不足的表现,通过车辙试验对比研究了结构层厚度、级配、材料以及施工控制等因素对沥青混凝土高温性能的影响,基于高温性能,提出了沥青混凝土结构层厚、级配、材料及施工控制的合理建议,为改善沥青混凝土的高温性能提供一定的参考依据。

As the typical diseases of asphalt pavement, rutting is caused by the lack of high temperature stability of asphalt concrete. Rutting test is carried out to research the influence of structural layer thickness, gradation, material and construction control and other factors on the high tem-perature performance of asphalt concrete. Based on high temperature performance, the suggestions on asphalt concrete structure layer thickness, gradation, materials and construction control were proposed which provide reference for improving high-temperature performance of asphalt con-crete.
