半刚性基层沥青路面厚度现状分析

Analysis on the thickness of the semi-rigid asphalt pavement

重点分析了半刚性基层沥青路面厚度现状,针对半刚性基层沥青路面的优点,指出其用于高等级公路路面结构的合理性,并对半刚性基层沥青路面的使用性能进行了研究,探讨了减薄沥青面层厚度的可行性,从而满足路面结构的强度和承载力的要求。

The situations of the thickness of the semi-rigid asphalt pavement at present are mainly analyzed. According to the advantages of the semi-rigid asphalt pavement its superiorities applied in high-grade highway are pointed out. In addition the road performances of the semi-rigid asphalt pavement are studied. The feasibility to reduce the thickness of the semi-rigid asphalt pavement is also discussed in order to meet requirements of pavement structure on strength and bearing capacity.
