摘　　要：为研究半柔性复合路面层间粘结力对路面结构层应力的影响。通过拟定路面交通量以及材料参数,通过BISAR软件进行设计路面典型结构层计算,设计出以半柔性复合材料作为上面层的典型结构层以及沥青路面结构层,并研究层间粘结对半柔性复合路面弯沉、剪应力、行车方向拉应力和荷载方向拉应力的影响。结果表明层间粘结对半柔性复合路面弯沉、剪应力分布具有一定影响,建议在设计时将层间粘结作为重点考虑指标之一。As research the influence of pavement structure stress of layer cohesive force of Semiflexible composite pavement.This paper uses the BISAR software for calculating the typical structure layer of the design pavement form the protocol road traffic and material parameters.Designing Semi-flexible composite pavement as the top layer of typical structure and the asphalt pavement structure layer.Influence the interlayer bonding Semi-flexible composite pavementt deflection,shear stress,driving direction tensile stress and load direction tensile stress.The results showed that the interlayer bonding status for composite pavement structure layer of the deflection and stress distribution has special significant influence.So it is suggested that in the design of the pavement of interlayer bonding for key consideration.
