Abstract

Abstract: Structural responses of Geogrid-Reinforced asphalt concrete pavement are analyzed in this paper based on principles of composite material mechanics and finite element method(FEM).The calculation about stress and displacement,with different load positions and different conditions of the base course,indicates the rational geogrid position in pavement structure,its anti-cracking effects and its reinforcement mechanism.

Key words: geogrid, asphalt concrete pavement, composite material, finite element method
