Concrete overlays of asphalt pavements (whitetopping) have been successfully used to rehabilitate deteriorated asphalt pavements for roads throughout the United States. Generally, whitetopping has been at least 4-in. thick. A thin overlay is normally considered to be less than 4-in. thick. Concrete whitetopping projects with thickness less than 4 inches have only limited use at this time, and a thickness of 2 inches has never been tried. The key was to find a location for an experimental project where accelerated evaluation was possible. Jim Deters of the Kentucky Ready Mixed Concrete Association fostered a couple of whitetopping projects in Kentucky on city streets with 3.5-in. thickness. Paving began September 21, 1991 and as of June 1992, the project was exposed to continual pounding of truck loads for 38 weeks. The current pavement condition remains excellent.
