| Abstract: | Dynamic response of multi-layered pavements subjected to FWD dynamic loads is analyzed by using two-dimensional axisymmetric finite element method. Correspondingly a Fortran90 program is developed. The results are compared with the available classic results to validate the accuracy of the algorithm. The program can be utilized as forward algorithm in back calculation of dynamic parameters, which is significant and valuable in practice. |
