Abstract:

In order to study the mechanical characteristics of ultra-thin asphalt overlay on old cement pavement of different joint load transfer capacity， the finite element model is established to analyze the stress at the center of joint at the bottom of asphalt overlay by ABAQUS. The results show that the first principal stress increases， and the maximum shear stress and equivalent stress decrease with the increase of ultra-thin overlay thickness. The three kinds of stresses increase linearly with the increase of the ultra-thin overlay modulus and vehicle load， and decrease with the increase of the joint load transfer capacity. The interlamination contact states have significant effects on the maximum shear stress of ultra-thin overlay. The order of the influence degree of factors are as follows： vehicle load， ultra-thin overlay modulus， joint load transfer capacity， interlamination contact state， ultra-thin overlay thickness. The increase of the joint load transfer capacity can significantly improve the fatigue crack life of the ultra-thin overlay， and the relationship between them is according to power function. The joint load transfer capacity of old cement pavement should be controlled according to the traffic load before ultra-thin overlay.
