[摘 要】本文从理论上分析了连续配筋砼基层沥青面层复合式路面的沥青面层的最大拉应力和最大剪应力
的分布情况,同时分析了各参数对最大拉应力和最大剪应力的影响,从而对连续配筋砼基层沥青面层复合式路面
结的沥青面层混合料类型及路用性能提出了有益的建议。

[Abstract]This paper makes a theoretical analysis of the distribution on maximum tensile stress
and maximum shear stress on asphalt SUrface layer of composite pavement of continuously reinforced con—
crete base and asphalt surface layer,analyses the effects of parameters on the maximum tensile stress and
maximum shear stress.So some beneficial suggestions are put forward on the mixture types and road per—
formance of composite pavement of continuously reinforced concrete base and asphah surface layer.
