ULTRA-THIN WHITETOPPING OF PAVEMENTS
Record Type: DOT
Illinois is continually looking for new and innovative methods for rehabilitating roadways. For pavements with high volumes of heavy traffic, asphalt overlays may not be strong enough to resist rutting and shoving. One method of eliminating these problems is to use a portland cement concrete overlay over the asphalt surface. This is known as "whitetopping." An ultra-thin whitetopping is less than four inches thick and is bonded to the underlying asphalt surface. The objective of this project is to evaluate and document the performance of an ultra-thin whitetopping. Since many Illinois pavements either have been widened or have had lanes added, some of the projects will include a bonded concrete overlay on some lanes and ultra-thin whitetopping on others. If ultra-thin whitetopping performs well and is cost effective, Illinois will have another alternative for pavement rehabilitation.
