Abstract: Using visco-elastoplastic-plastic finite element method, the resistant ability to rutting occurring in Heilongjiang province express way has been analyzed. Base on the numerical results, it has been found that the location of rutting occurring mainly existed in middle course, So some modified measurement of middle course to enhance the resistant rutting ability has been proposed. At the same time, A new user Subroutine, which is named dload of ABAQUS, has been employed to simulate the moving vehicle load ,this article has proposed a new method to predict rutting behavior .
