While not a new product, there is great renewed interest in Roller Compacted Concrete (RCC) and its use in industrialized parking areas, in local streets and as highway shoulders.
IRMCA, its promotion partners and many of its members are actively presenting the benefits and possible applications to state, municipal, county as well as heavy-duty commercial decision makers. It is important to note that RCC is not being promoted as a competitor to full-depth PCC, but rather as a viable option for satisfying special requirements or as part of a composite placement design.
RCC utilizes the same materials as conventional concrete and derives its name from the manner in which the material is placed and finished. Most always delivered in dump trucks, the very stiff RCC is placed in front of a traditional spreader/paver and then rolled to meet its specified density. The result is a very dense, high strength, and rapidly placed product that has also shown positive economic value.

Also, the Portland Cement Association and Iowa State University have produced the Guide for Roller-Compacted Concrete Pavements which to this date is the definitive publication on RCC. It is available at a very low cost.
