Research Study Title: and Implementation of the Design, Construction and Rehabilitation of Rigid Pavements" 16. Abllract This report deals with the development of a computerized system for analyzing and designing concrete pavement slabs subjected to drying, shrinkage. and drop in temperature stresses with time. The system is capable of analyzing a given jointed reinforced concrete pave- ment slab design for crack occurrence. It is also capable of designing either a reinforced or a non-reinforced slab. It has been found that the main factor acting in crack generation is the fric- tion between the slab and the underlaying pavement course, with higher stresses in the slab occurring with higher friction values. This work is a useful tool in the study of cracking in concrete pavement slabs because it is relatively simple to superimpose the stresses due to drying, shrink- age, and drop in temperature on the stresses generated by factors such as wheel load, warping, etc. in order to get a more realistic ttstate of stress" in the slab. 17.
