Finite Element Simulation and Analysis of Practical Inter-layer Bonding State of Semi-rigid Pavement

LI Tiehong,LI Chunxiao  
In order to analyze stress and deflection distribution in semi-rigid pavement in practical inter-layer bonding state,and meanwhile provide necessary examination means for conventional pavement design,this paper simulates the practical inter-layer bonding state of pavement by means of the contact model of general finite element software in accordance with the related test results,and analyzes stress and deflection changes of pavement in practical inter-layer bonding state and under influence of adverse factors into consideration such as high temperature and overloading,etc.The analysis results show that the simulation for practical inter-layer bonding state of pavement by means of the contact model of the finite element software is feasible,and the friction coefficient if possible can be determined based on the actual test results,otherwise,can be selected between 0.6~0.8.
