半刚性基层沥青路面应用探讨

Semi-rigid application of asphalt pavement

目前的半刚性基层沥青路面结构和材料设计中存在许多问题,导致了沥青路面结构早期破损严重,使用寿命远低于设计使用年限。文中通过对半刚性基层沥青路面特性及应用的分析和再认识,提出了长寿命沥青路面的设计理念。

currently semi rigid pavement structure and material design of many problems,resulting in early damage of asphalt pavement serious,life is far lower than the design life. Based on the semi-rigid base asphalt pavement characteristics and application of analysis and understanding,and made long life asphalt pavement design.
