Virginia Report Details RCC Project with Asphalt Overlay

The Virginia Department of Transportation (VDOT) has released a report that documents construction procedures for a roller-compacted concrete (RCC) pavement with an asphalt overlay. As per VDOT and the Virginia Center for Transportation Innovation and Research (VCTIR), the purpose of this study was to document the construction procedures and provide lessons learned for a RCC project that covered approximately two lane miles (134,000 ft2) at the Park & Ride lot and Staffordboro Boulevard in Stafford County. The mixture used had 15% fly ash to provide improved durability and sustainability. Portions of the pavement were also opened within 5 to 6 hours after paving with no visual damage to the pavement and most sections were opened within 48 hours.

Based upon the experience gained from this project, VCTIR believes that "RCC should be considered by VDOT in future field trials, particularly for applications where fast construction of rigid (concrete) or composite pavement is needed." This successful field trial demonstrates one of the many uses of RCC and how it may be used in early loading applications.
