沥青稳定碎石排水基层力学特性分析及材料试验研究

Mechanical Characters of Asphalt Treated Permeable Base

沥青稳定碎石排水基层可以显著减少沥青路面早期水损害,通过对设置排水基层的沥青路面结构进行力学分析,考察加入排水基层对路面结构应力和变形状况的影响,从结构角度提出对排水基层材料的性能的要求,并且对设置排水基层的半刚性基层沥青路面结构设计提出相应的建议。

Asphalt Treated Permeable Base(ATPB) can improve pavement performance and extend service life.The paper analyzed the mechanical characters of pavement structure including the ATPB,researched the influence of strain and stress on the pavement structure when added ATPB,gave the requirement of ATPB material and put forward the suggestion of the pavement structure design.
