Abstract Using a flexible asphalt pavement structure with a graded crushed stone base is an effective means to solve reflection cracking, which frequently occurs in the semi-rigid asphalt pavements in Xinjiang. Control indicators are analyzed based on the damage form of the flexible asphalt pavement with a graded crushed stone base.

2021324 · The test results indicate that there are three obvious instability behavior stages of large-size graded crushed stone under cyclic rotating axial compression: elastic stability, plastic creep, and incremental plastic failure. Large-size graded crushed stone has a higher critical stability load stiffness than conventional-size graded crushed stone.
