Paper presented at the South African Transport Conference 17 - 20 July 2000 "Action in transport for the new millennium", CSIR International Convention Centre, Pretoria, South Africa. ABSTRACT: Strength and deformation behave of layer system is important to road engineering. According to thermo-elastic theory, expressions of stress and displacement of homogeneous layer system under both
temperature change and static load are presented in this paper. The static loads enclodes single or poly circular loads and Fourier-Hankel transformation is used in study. The results of this study can be easily used in road engineering.
