| Abstract: | The dynamic equation of asphalt pavement and the basis theory of NEWMARK integration method are introduced. The dynamic infinite element procedure to calculate the mechanic response of both inverted structure and typical structure under dynamic load is applied. The results show that mechanic response of inverted structure is bigger than that of typical structure, and the change tendency is similar. What＇s more, mechanic response of dynamic load is smaller than that of static load and the design point stresses of inverted structure are smaller than tolerances of pavement structure material. |
