Abstract
The U.S. Army Corps of Engineers' design procedure for roller-compacted concrete (RCC) pavements assumes that no load transfer is achieved at RCC joints or cracks. This is in contrast to the Corps of Engineers' rigid pavement design procedure for airfields, parking areas, and open storage areas, where a 25 percent load transfer is assumed for all joints and cracks. The no-load-transfer assumption for RCC pavements is conservative and is based upon limited data that indicated that RCC pavement joints did not achieve a 25 percent load transfer. The purpose of this study was to identify common types of RCC pavement joints and cracks, to determine the load transfer characteristics of these joint and crack types at 12 RCC pavement test sites using the falling weight deflectome-ter and to indicate the effect of incorporating these load transfer characteristics within the corps' RCC pavement design procedure. Thirteen RCC pavement joint and crack types were identified. The mean load transfer achieved at these jo...
