In order to study the characters of asphalt concrete pavement with cracks,based on viscoelastic fracture mechanics theory and plane strain FEM,the distribution of relaxed stress intensity factor(SIF) with time was determined using ABAQUS software when the influencing factors including the reference temperature,the changing temperature on the pavement surface and the length of cracks were changed.

A practical algorithm determining the optimal relaxation factor of SOR iterative methods;

The effect of the relaxation factor on the convergence and the calculation efficiency in the one step forming simulation approach was studied through a series of the practical examples.

Using adaptive calculation method, the relaxation factor ω is changed according to increasing or decreasing of the number of iteration within the range from 0 to 2, thus dynamic adjustment of ω can be obtained.
