Abstract:Until the early 1990s, curling and warping of Portland cement concrete pavement did not concern pavement engineers in many transportation agencies. Since beginning construction of the interstate system in the United States in the late 1950s through the late 1980s, the performance of Portland cement concrete pavement has been associated with properties of concrete as a pavement material. In those years developed standards and design guidelines emphasized better concrete materials and construction control. At the time, combining curling and loading stresses was quite controversial due to the nature of the load-carrying capacity of concrete pavement and the occurrence of types of loads. Arguments developed that the types of loads (traffic and curling) rarely occurred at the same time of day. The concrete pavement design principle did not include the effects of curling and warping of concrete pavement as determining design factors in pavement performance.
