Roller Compacted Concrete

Roller Compacted Concrete
Stein is one of the few paving companies in Chattanooga to offer Roller Compacted Concrete (RCC). RCC, a stong, long lasting paving material that accomodates heavy loads, is a economical construction method for dams, off-highway pavement projects, heavy-duty parking and storage areas, and as a base for conventional pavement. RCC is a stiff, zero-slump concrete mixture with the consistency of damp gravel comprised of local aggregates or crushed recycled concrete, Portland cement, and water. The mixture is placed and roller compacted with the same commonly available equipment used for asphalt pavement construction. The process requires no forms, finishing, surface texturing, or joint sawing and sealing.

The low water-cement ratio in RCC has higher or greater strength than conventional concrete. RCC's high-strength properties, ease of construction and high rate of production makes RCC more economical than a flexible pavement. Additionally, more than 20 years of exposure as logging roads in cold climates have demonstrated that RCC has resistance to freezing and thawing.
