Paper Title:
The Elastic Parameters Analysis of Asphalt Overlay the Crashed Cement Concrete Pavement Based on Reliability Theory
  Abstract

Overlay asphalt on the crashed cement concrete pavement is used widely in old cement concrete pavement reconstruction. at present, Aiming at the differences of mechanical response of this compound pavement structure system, paper introduced the road deflection as the control index and discussed the influence to road reliability index caused by elastic parameters of each layer as well as the sensitivity analysis based on the stochastic finite element method and reliability theory. Results show that the reliability index is greater as the asphalt overlay elastic modulus and crashed layer elastic modulus is increasing and lower as the increase of coefficient of variation, also the elastic modulus of asphalt overlay play a most important role in the diversification of deflection and bottom stress.
