In the existing guide of pavement design for industries or port area, the pavement system is composed of concrete block or asphalt surface layer and CBM3 rigid base. The structural failure is limited by only the fatigue cracking at the base layer due to horizontal tensile stress. However, in asphalt-surface pavement or composite pavement, excluding the distress criteria such as rutting and cracking may cause the structural and serviceability failure at the early age. This paper provides the comprehensive study of sensitive analysis of composite pavement by investigating the effects of layer thickness and modulus to the critical stresses and strains corresponding to the fatigue cracking of asphalt surface and base layer, and rutting in asphalt surface to understand the distress effects to the design. The composite pavements are analyzed in the finite element analysis of axisymmetric problem model. The results of this study indicate that composite pavement (i.e. with rigid base) shows no sign of horizontal tensile strain at bottom of asphalt layer. Therefore, this pavement system may eliminate the fatigue cracking in asphalt surface and excluding this criterion in the design may have no problem to the structural performance. However, the horizontal tensile stress, causing the fatigue cracking in base layer, is very critical. Therefore this criterion must not be avoided in the design. Moreover, rutting in asphalt is also a critical criterion to be considered in the design. Rut depth is very sensitive to stiffness and thickness of the underlying layers and the asphalt layer itself.
