Roller-compacted concrete (RCC) is an accepted and economical method
for the construction of dams and pavements. Achieving adequate compaction is essential in the development of the desired properties in the hardened material. The compaction depends on many variables, including the materials used, mixture proportions, mixing and transporting methods, discharge and spreading practices, compaction equipment and procedures, and lift thickness. The best performance characteristics are obtained when the concrete is reasonably free of segregation, well-bonded at construction joints, and compacted at, or close to, maximum density.
