FEM ANALYSIS ON GEOGRID REINFORCED ASPHALT CONCRETE PAVEMENT

摘要

In this paper, numerical calculation contrast analysis on the stress in asphalt pavement with and without reinforcement, as well as in different connective operation condition between geogrid and pavement is conducted. The results demonstrate that the optimum position varies with the different requirements of disease prevention. Geogrid can effectively improve stress condition when penetrating cracks are developed in base course. At the same time, the reinforcement mechanism and crack prevention function of geogrid are revealed, which show that geogrid reinforcement technology has priority to other methods.
