Roller-compacted concrete, or RCC, takes its name from the construction method used to build it. It's placed with conventional or high-density asphalt paving equipment,then compacted with rollers. Roller-compacted concrete has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone.

The American Concrete Institute (ACI) defines roller compacted concrete (RCC) as "concrete compacted by roller compaction that, in its unhardened state, will support a roller while being compacted." The term "roller compaction" is defined by the ACI as "a process for compacting concrete using a roller, often a vibrat-ing roller."
Roller compacted concrete pavement (RCCP) is a dry mix that is rigid enough to bear the weight of 20 ton rollers and stiff enough to be compacted by high density pavers. The standard means of placing RCCP is by first being placed through a standard or high density paver and subsequently compacted by a non-vibratory or vibratory roller.

Roller Compacted Concrete (RCC) is a no-slump concrete compacted by vibratory forces. RCC has demonstrated life spans in Canada of 40+ years and is found worldwide in dams, heavy industry areas (logging, lay down areas, ports, container yards, etc.), airports, roads and streets, parking lots, base for overlays, and more.
RCC "The Alternative Pavement". Roller Compacted Concrete is a mixture of cement, aggregates, and low water content mixed in a continuous mix pug mill. Cost savings in using RCC are achieved from faster production rates, no reinforcing steel used, and reduced labor costs.
We are seeing more news surrounding one of the more exciting innovations in the concrete industry: roller-compacted concrete (RCC). As evidence, ASTM International is formalizing a method for making a cylindrical specimen of RCC in a gyratory compactor. Test Method for Preparation, Compaction and ...
Production of Roller-Compacted Concrete Introduction Definition Roller-Compacted Concrete (RCC) takes its name from the method used to construct it. RCC refers to a stiff, zero-slump concrete mixture that is placed (typically with asphalt-type paving equipment) and then compacted with rollers.
Roller-Compacted Concrete Pavement . This Tech Brief presents an overview of the best practices for roller-compacted concrete pavement.

TCP Concrete Construction was founded in April, 1996. We provide turn-key Roller Compacted Concrete Paving, Cement Stabilized Base Course and Lean Concrete (Econocrete) Base Course for military, state, county, municipal and private development projects. Asphalt and concrete, move over and make way for Roller Compacted Concrete – RCC.
Development of roller-compacted concrete (RCC) caused major shift in construction practice of mass concrete and pavement slabs. Large amounts of mineral admixtures (fly ash, slag, and natural pozzolan) are used in RCC to reduce both adiabatic temperature rise of …
Roller-Compacted Concrete (RCC) is a special type of concrete that incorporates typical concrete constituents (i.e. aggregate, cement, water, etc.) but in different proportions. Due to the dry nature of RCC, it is placed using a paver and rollers, similar to the construction process of asphalt concrete.
