Rennick Yard RCC Pavement Design and Construction

by Kevin L. Delva, Centennial Engineering Inc, Arvada, CO, USA,



Document Type: Proceeding Paper

Part of: Roller Compacted Concrete II

Abstract:

Rennick Yard roller compacted concrete paving project consisting of 136,000 multiplied by (times) yd**2 (113,710 m**2) was completed in June 1986. The design load for this project was a piggy-packer fork lift with a wheel load of 110 kips (50 Mg). The Portland Cement Association's guidelines for Industrial Pavements was used to determine the 15 inch (381 mm) required thickness. The flexural strength of the RCC material (4. 8 MPa) was determined in the field by constructing a test section. The contractor selected two ABG 410 Titan pavers to place the RCC material. The pavers operated in tandem with a 10 ton (9100 kg) following each paver. Curing of the concrete was accomplished using three water trucks, maintaining the surface damp for seven days. One year after completion of the project a qualitative test was made to determine the load transfer at the joints. Joint efficiency was found to range from 92% for the transverse contraction to 20% for the weakest longitudinal joints.
