| 摘 要： | 大粒径透水性沥青混合料(LSPM)能有效防止反射裂缝,并迅速排出沥青路面内的水分,具有很高的回弹模量和抵抗变形的能力。本文结合试验路段,对LSPM的材料要求、配合比设计和温度应力进行分析,探讨了沥青路面结构层参数对温度应力的影响规律,其结论LSPM可直接用于旧路改造或新建沥青路面的柔性基层中。

| Abstract: | LSPM can effectively prevent reflective cracking,and rapid discharge of water within the asphalt pavement with a high modulus,which has the ability to resist deformation.This paper is combined with test sections of the material requirements of the LSPM,mix design and thermal stress to analyze the law of the LSPM on temperature stress.At last,it makes a conclusion that LSPM transformation of the old road can be directly used or new flexible asphalt pavement Grassroots. |
