Roller compacted concrete (RCC) is a zero slump portland cement concrete mixture that has been used since the early 1970's in massive concrete structures. Iowa Highway Research Board project HR-300 was established to determine if this type mix could be used to pave roads on the Iowa road system.
Roller Compacted Concrete Quality Control Guide 1.0 SCOPE Over the past decade, roller compacted concrete (RCC) has been successfully used on projects ranging in complexity from large dams to small building pads.
Apr 16, 2012 · The use of roller-compacted concrete (RCC) has extended beyond heavy-duty pavements. It is now being used for streets, county roads, department of transportation (DOT) highway shoulders, and ...
Roller compacted concrete, or RCC, takes its name from the construction method used – it is placed by modified asphalt paving equipment, but it is stiff enough to be compacted by vibratory rollers. RCC has the same constituents as conventional concrete – cement, water and aggregates – and requires no formwork or reinforcement.
This paper explains the development of a roller-compacted concrete for constructing or renovating concrete pavement (RCCP), using lignite fly ash in Thailand. A Title: Mix Proportioning and Properties of Roller-Compacted Concrete …
Roller-Compacted Concrete (RCC) can be considered as both a construction material and a construction method.

A book of broad interest to professionals, dam engineers and managers, and to organizations responsible for dam development and management, RCC Dams offers a topical account of the design and operation of roller compacted concrete dams, describing the latest developments and innovative technologies in the field.
Roller compacted concrete has the same basic ingredients as conventional concrete, but it is created from a mix that is stiff enough to be compacted by vibratory rollers. RCC is typically constructed without joints, and it does not require forms, finishing, or reinforcing.
Roller Compacted Concrete (RCC) is a relatively dry concrete mix that is installed with a paving machine and then rolled, just like asphalt. It is sometimes called “white asphalt”. This installation method keeps construction costs lower than conventional concrete and very competitive with asphalt.
