Abstract:

Whitetopping, the placement of portland cement concrete (PCC) overlays on deteriorated asphalt concrete (AC) pavements, has been used for more than 60 years. These overlays have typically been at least 125 mm thick. Recently, however, a new technology known as Ultra-Thin Whitetopping (UTW) has emerged. UTW involves placement of a thin (50- to IOO-mm) concrete overlay to restore AC pavements that have cracked and/or rutted. The first experimental section of UTW was constructed in 1991 on an access road to a landfill in Louisville, Kentucky. Since then, more than 170 UTW projects have been constructed across the United States.
