Abstract:Concrete pavements are subjected to a variety of stresses and, as a result, the pavement slab is in continuous motion. Some of the more significant stresses present are environmental loads, or those developed by the thermal and shrinkage movements of the paving material. When the environmental loads are combined with the wheel and gravity loads, conditions exist which control the ultimate life of the concrete pavement. The environmental stresses are a function not only of weather but also of the material properties of the pavement. Therefore, in pavement design, it becomes important to consider the material properties of the paving materials from an environmental viewpoint.
