325.10R-1 This report covers the present state of the art for roller-compacted concrete pavements. It contains information on applications, material properties, mix proportioning, design, construction, and quality control procedures. Roller-compacted concrete use for pavements is relatively recent and the technology is still evolving. The pavement consists of a relatively stiff mix- ture of aggregate, cementitious materials, and water, that is compacted by rollers and hardened into concrete. Keywords: Aggregates; cements; compaction; concrete construction; con- crete durability; concrete pavements; consolidation; curing; construction joints; density; mixing; placing; Portland cement; roller compacted con- crete, strength.
