Performance Analysis of LTPP Test Pavement Sections

抄録

In this paper, the numerical models and performance models for pavement performance are proposed and incorporated into the finite element program to predict the pavement distress such as rutting and fatigue cracking for LTPP test pavement sections in USA, and the results are compared with the measured distress. The numerical approach for the theory of plasticity and fractural mechanics are also developed for the pavement performance analysis. It is shown that the proposed constitutive models and distress models can predict the pavement distress and the results are close to the measured distress.
