Coarse Aggregate for PCC (Portland Cement Concrete)-Pilot Study Evaluation

摘要

The study investigated material properties of continuously reinforced concrete pavements (CRCP) that used siliceous river gravel or crushed limestone as the coarse aggregate material. Laboratory measurements of the concrete mix properties were made for both coarse aggregates. These measurements were used to develop a set of predictive equations to simulate concrete behavior by coarse aggregate type. Predictive equations of concrete behavior were used as input to CRCP-4 computer program analysis. A strategy for developing CRCP steel specifications was formulated on the basis of CRCP-4 program analysis results.
