Abstract

Modern Roller-Compacted Concrete (RCC) pavements are being increasingly specified in the U.S. because of their construction expediency, material cost savings, and early opening to traffic. RCC mixture proportioning and adjustments are not as well understood as conventional concrete mixtures. The objective of this study is to provide guidance in selecting the initial RCC mixture proportions and adjustments as needed to achieve target properties. A statistically-based experimental design was developed to determine the combined effect of three independent, mixture variables on RCC properties: cementitious content, sand percentage, and fly ash dosage. Predictive response equations and contour plots were derived to predict moisture-density and strength based on the RCC mixture proportions and constituents. Significant increases in sand percentage in the RCC mixture was found to have a negative effect on density and strength of RCC.
