Results from the Concrete Pavement Technology Program Task 3 Project on the Performance and Design of Whitetopping Overlays on Heavily Loaded Pavements

In 2000, the Innovative Pavement Research Foundation (IPRF) and Federal Highway Administration (FHWA) initiated a project under the Concrete Pavement Technology Program with the goal of developing guidelines for designing, constructing, and rehabilitating whitetopping overlays. The first goal was to summarize available information and document how the industry considers whitetopping overlays among various pavement rehabilitation alternatives. Although whitetopping overlays have been constructed for decades, their recent popularity has stemmed largely from a renewed demand for longer lasting but cost effective solutions for hot-mix asphalt (HMA) pavement rehabilitation. The second goal of the project was to extrapolate beyond this knowledge base and into the state of the art. To accomplish this, a comprehensive design and construction process was developed for whitetopping overlays that provides the industry with a practical and reliable means to further utilize this important overlay type. This presentation synopsis summarizes the key findings from this important effort.
