RCCP ONE ALTERNATIVE FOR LOW-SPEED

The advantages of roller-compacted concrete (RCC) include the ability to be placed in large volumes rapidly without the use of expensive equipment or skilled labor, resistance to petroleum spills, frost resistance, negligible creep, and it does not need additional surfacing. The in-place characteristics of RCC material are proportional to its density. The surface texture and smoothness limit RCC pavements to traffic speed below 40 mph. The densification of in-place RCCP is important. Only by achieving the designed degree of compaction in the field can the long-term design performance of the on-site project be achieved. This article discusses the mix and material handling factors that affect the density of RCCP: aggregate; cement; water; mixing plant; transportation; paver; and compactor. The test strip, and the determination of the machine settings for a given project are described. The compaction of RCCP is also discussed.
