Abstract

In an RCC demonstration project that consisted of a 1525-ft-(465-m)-long roadway and a 100 × 39-ft (30 × 12-m) parking lot, the effect of several construction parameters on physico-mechanical properties of the pavement and the had transfer efficiency at its joints and cracks were investigated. This paper reports experimental results on lay-down and final densities as affected by paver speed and rolling pattern, the strength of laboratory-made specimens using the vibratory hammer method as a function of mixes with slightly different aggregate gradations, cracking patterns at 7 months from construction as affected by saw-cut joint spacing, and load transfer efficiency at natural cracks and saw-cut joints. Overall, the results fall within the expectations of the program and confirm the suitability of current construction practices for RCC paving applications.
