Ultra-thin whitetopping is a new pavement maintenance tool that is gaining popularity, although this rehabilitation technique is still in the research stage. A 100-mm (4-in) concrete overlay is placed atop an existing asphalt pavement to renew its life, ride, and surface. This article describes some of the advantages of the whitetopping technique, which include early opening to traffic after placement, cost of whitetopping as compared to the repetitive costs of asphalt repaving, and superior bonding of asphalt and concrete. Experimental whitetopping projects in Iowa, Kentucky, and Tennessee are described. Research results indicate that whitetopping may provide another rehabilitation option, particularly for low-volume city streets and rural routes.
