Title: Prediction of permanent deformation in subgrade of asphalt concrete pavement
Abstract: It briefly presents the state of rutting in flexible pavement foundation under axle cyclic loading.Based on the South Africa heavy vehicle simulator test data,a practical model for calculating permanent deformation of subgrade soils in flexible pavements is proposed.The model takes into account the subgrade soils material characters,stress and strain field in subgrade under axle loading and the number of cyclic loading.In the end,an illustrative example is given for the prediction of rut depth development in a flexible pavement subgrade soil.
