Theoretical Research of Vertical Crack Propagation in Overlaid Cement Concrete Pavement

Abstract:

In this paper, overlaid cement concrete pavement with crack is considered based on fracture mechanics. Cement concrete pavement is reduced to an elastic plate on Winkler foundation. Fourier integral transform, residue theorem and Lobatto-Chebyshev integration formula are used to obtain the analytical solutions of this problem. To analyze the effect of overlay for the old pavement, stress intensity factors ofItype crack and II type crack are calculated respectively for various overlay thicknesses, elastic moduli of the overlay. The stress intensity factors of the crack tips in the pavement with 10cm thickness overlay are reduced heavily. However, stress intensity factors are less affected by elastic modulus of overlay material.
