半刚性基层沥青面层合理厚度研究

Study on the Reasonable Thickness of Semi-rigid Base Bituminous Pavement

对半刚性基层沥青路面而言,其主要承重层是半刚性基层,而沥青面层一般只起功能作用,不起强度作用。因 此,得出沥青面层满足力学及路面使用性能的合理厚度推荐范围,对工程设计部门具有重要的参考意义。

As to the semi-rigid base bituminous pavement, the main bearing weight is basis on the semi-rigid layer. The bituminous pavement has a normal function, without any bearing strength. So, we find that the thickness of bituminous pavement could be satisfied the mechanics and road surface applica-tion function.
