Innovative RCC Approach Chosen for Technical School Parking Lot

Print Print this Article | Send to Colleague

Roller-compacted concrete’s (RCC) durability and cost-savings made it the pavement of choice for the new Marion County Regional Institute of Technical Excellence parking lot in Kimball, TN. Using a innovative delivery system, the 1,500 cubic yard job was successfully completed in five days. The crew did not discharge the RCC directly from a ready mix truck into dump trucks that would deliver it, as is typical. Rather, the concrete was discharged from trucks onto a concrete slab and the contractor used a front-end loader to load the dump trucks. While the front-end loader filled the dump trucks, the ready mix trucks refilled the RCC pile with 50 to 60 cubic yards of material. The process prevented running out of material and there was little segregation because a well-graded material was used with the maximum size aggregate being only 0.5 inches when the proper mix was used.
