Abstract

In order to explore the distribution law and internal mechanism of asphalt pavement layer disease of concrete beam bridges, this paper studied four prestressed concrete continuous beam bridges with different degrees of asphalt pavement layer disease and used a new method of bridge deck pavement layer area division and disease statistics to carry out field investigation. Through the investigation and quantitative statistics of the disease distribution in each pavement layer area, as well as the finite element simulation analysis of bridge structural mechanics and pavement layer, it is found that most of the areas with serious diseases are areas with large tensile stress, shear stress, and vertical deflection, which indicates that the adverse mechanical response caused by load is an important internal reason for the bridge pavement layer disease.
