www.acpa.org Quarter 4, 2018 9 NCDOT Guilford and Randolph Shoulder Reconstruction, High Point, NC CONTRACTOR: Andale Construction, Inc. OWNER: North Carolina DOT ENGINEER: NCDOT Department of Highways, Division 7 When the North Carolina DOT needed to reconstruct a failing asphalt shoulder along the heavily traveled Inter- state in Guilford and Randolph Counties, they opted for roller compacted concrete. This shoulder reconstruction marked the DOT’s first use of RCC and served as a pilot project. The total project included 14 miles of 10 ft. outside shoulder construction, which was expected to take at least six weeks, considering traffic restrictions, weather, and scope of the work. Andale completed the construc- tion in 21 paving days. This project was so successful that the DOT increased the original contract to install RCC on the 4 ft. inside shoulders, as well as the removal and installation of exit and entrance ramps. In all, the contractor placed 83,000 SY of 8 in. RCC pavement. The contractor used a specialized trowel, which created a smooth, consistent, and durable surface. In fact, no cor- rective actions were required on any of the pavement. RCC (Special Application) E X C E L L E N C E A W A R D S MEMBER
