Finite Element Modeling of Asphalt Concrete Pavement Reinforced with Geogrid by Using 3-D PLAXIS Software

Mohammed Abbas Aljumaili


This paper presents an axisymmetric finite element (FE) model to analyze the behavior of unreinforced and geogrid reinforced asphalt concrete pavement subjected to various tire pressures. The model was loaded with an incremental loading from 100 to 600 kPa with 50 kPa increment and the critical pavement responses such as total stress and vertical surface deflection were determined for unreinforced and geogrid reinforced flexible pavement. The results indicated that during static loading, a moderate effect on the pavement behavior was observed due to the reinforcing geogrid layer. The effect of geogrid position at bottom of asphalt concrete surface layer on pavement response was clear. The results also showed that moderate improvement in pavement system behavior was obtained by adding a layer of geogrid reinforcement at inference of asphalt concrete base layer and subbase layer.
