摘要

随着沥青路面力学-经验设计和分析方法的发展,路面材料参数的研究显得越来越重要.文中利用MTS 材料试验系统对含有透水基层( ATPB) 的ATPB-25 和ATPB-30两种沥青混合料进行了动态模量试验测试.试验测试中,根据沥青混合料所处的温度环境设定了不同的测试温度和加载频率.然后根据测试结果生成了该沥青混合料的全时域动态模量主曲线以及相对应的主曲线方程.这些试验研究可为含有ATPB 的沥青路面结构优化设计和性能分析预测提供高质量的参数,对于延长沥青路面的使用寿命具有重要意义.

Abstract

With the development of the asphalt pavement mechanistic-empirical design and analysis methods,the research of pavement material parameters is becoming more and more significant. In this investigation,the MTS system was used to do the dynamic modulus test for ATPB-25 and ATPB-30,which are both asphalt treated permeable base( ATPB) mixture. During the test,different measuring temperatures and loading frequencies are set according to the temperature environment of the asphalt mixtures. Then,based on the test results,a full time-domain dynamic modulus master curve and corresponding master curve equation of the asphalt mixture are created. By these experiments,high-quality parameters for the optimization design and performance analysis of asphalt pavement structure with ATPB can be established. These studies are of great significance in extending the service life of the asphalt pavement. asphalt mixture; dynamic modulus; master curve; pavement mechanics; empirical design
