摘　　要：车辙是沥青路面的主要病害之一,但目前对沥青混合料高温稳定性的研究还有欠深入。本文在分析高温稳定性的影响因素的基础上,选取了几个AC-13C型典型级配,分别进行了各项沥青混合料高温稳定性的试验研究。结合试验数据,讨论了矿料级配对AC-13C型沥青混合料高温稳定性的影响。在此基础上提出湖北地区重载交通下上面层沥青混合料矿料级配的选择建议。The rust is one of the main distress of bituminous pavement.But the high temperature stability of bituminous mixture has not been revealed thoroughly so far.Based on general analysis of the acting factors that affect the the high temperature stability,the various tests about the high temperature stability of bituminous mixture conducted are tested by the way of using several representative grading of AC-13C respectively in this paper.Through analyzing the test data,this paper discusses the effect of mixture＇s grading on the high temperature stability of AC-13C bituminous mixture.On the base of that,this paper puts forward the advices of choosing grading of the top surface bituminous mixture under over-loading traffic in Hubei Province in China.
