USING ULTRA-THIN CONCRETE OVERLAYS ON ASPHALT

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.
