DRYING SHRINKAGE AND TEMPERATURE DROP STRESSES IN JOINTED REINFORCED CONCRETE PAVEMENT

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 pavement 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 friction 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, shrinkage, and drop in temperature on the stresses generated by factors such as wheel load, warping, etc. in order to get a more realistic "state of stress" in the slab.
