Study on Shear Performance and Construction Technology of the Stress Absorbing Layer in Underground Road Composite Pavement

Abstract:

In this paper, a composite pavement stress absorbing layer is researched. Through the creation of the finite element analysis model of the composite pavement, the paper analyzed the shear stress and influencing factors such as a different level of force, the contact between the different layer, shear stress conditions, the surface layer modulus and thickness, base thickness, soil base resilient modulus. At last, the optimum thickness of the composite pavement structure layers is put forward.
