级配对AC-13C型沥青混合料水稳定性的影响

Effect of Grading on Water Stability of AC-13C Bituminous Mix ture

选取几个AC-13C型典型级配,分别进行了各项沥青混合料水稳定性的试验研究.结合试验数据,讨论了矿料级配对AC-13C型沥青混合料水稳定性的影响.并采用贝雷法检验了各AC-13C的级配组成,在此基础上提出南方地区重载交通下上面层沥青混合料矿料级配的选择建议.

In this paper the water stability of bituminous mixture are examined by the way of using several representative grading of AC-13C respectively. Through analyzing the test data, this paper discusses the effect of mixture＇s grading on the water stability of AC-13C bituminous mixture, and checks up the grading composing of several AC-13C mixtures by usi ng the method of Bailey. Based on the results, this paper puts forward the advices of choosing grading of the top surface bituminous mixture in case of over-loading traffic in the south China.
