- Abstract:
-
In order to analyze the base stress of the new pavement structure of asphalt pavement of poor concrete base layer, the load stress of poor concrete base layer is calculated by finite element analysis method, and the influence of asphalt surface thickness on it is analyzed by elastic layer theory, and the calculation formula of base load stress is derived. According to the temperature field and maximum temperature gradient of different natural divisions, the finite element solution of the temperature stress of the base layer in the asphalt pavement of the poor concrete base layer is obtained, and the calculation formula of the base temperature stress is proposed. The above two formulas are important bases for the design of base layer thickness in asphalt pavement structure of poor concrete base layer.
