摘要：

A new approach to evaluate shear resistance of bonding layer in concrete bridge deck asphalt pavement was proposed. The distributions for shear stress and normal stress in the interface between asphalt pavement and bridge slab under vertical and horizontal load were analyzed by finite element method. Based on the scattergram of shear stress and normal stress, the conception of shear stress critical boundary was proposed. Parameters of pavement and load were considered to analyze its effects on critical boundary. Also, equation formation of critical boundary was tested by χ2-test. The basic condition to guarantee the performance of shear resistance for bonding layer was that there was no intersection of shear stress critical boundary and shear intensity envelope line, which was the design standard for bonding layer in concrete bridge deck asphalt pavement. Finally, a case study was presented.
