1.
It also points out that the addition of the thickness of the base course can lower the strain of the tensile strain of the base course and the surface deflection,while the addition of the soil modulus can reduce the surface deflection.
根据国内外研究经验,对沥青稳定基层设置、选取不同的基层模量,应用理论方法对不同情况下的沥青路面结构进行计算,结果表明:增加基层模量有利于降低基层底和土基顶的应变,增加底基层厚度能降低基层层底拉应变和表面弯沉,增加土基模量能减小表面弯沉。
