Roller Compacted Concrete Pavement, is a type of non-reinforced concrete pavement placed with high density paving equipment and then compacted with vibratory rollers. While the finished product is essentially concrete pavement, the engineering and construction of this pavement is very different from conventional concrete pavement.
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.
Transportation Research Record 1062 1 Mix Design, Thickness Design, and Construction of Roller-Compacted Concrete Pavement THOMAS D. WHITE ABSTRACT Roller-compacted concrete pavement (RCCP) is a technology that involves the use of
Roller compacted concrete (RCC) is broadly defined as a stiff, low-water concrete that is mixed and paver-paved at a no-slump consistency and then compacted with vibratory rollers. RCC has similar strength properties and consists of the same basic ingredients as conventional concrete—well-graded aggregates, cementitious materials, and water ...
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.
The concrete mix achieves a high density and cures over time into a strong monolithic block. Roller compacted concrete is typically used for concrete pavement. Roller compacted concrete dams can also be built, as the low cement content causes less heat to be generated while curing than typical for conventionally placed massive concrete pours.
RCC stands for Roller Compacted Concrete that is commonly used for dams in hydro power plants. Below is a typical mix design that meets the normal requirements of a RCC dam. Depend on project specifications and actual
ash concrete. INTRODUCTION More than 250 RCC Dams have been constructed in 40 countries. And the dam volume becomes large steadily based on the actual results and the development of construction technique and mix proportions. In Japan, a term of “RCD (Roller Compacted Dam)” is used for RCC (Roller Compacted Concrete) Dam.

ACI-207.5R-11 Report on Roller-Compacted Mass Concrete. Roller-compacted concrete (RCC) is a concrete of no-slump consistency in its unhardened state that is typically transported, placed, and compacted using earth and rockfill construction equipment.
Use of Roller-Compacted Concrete Pavements for Container Terminals . Roller Compacted Concrete (RCC) is a zero-slump concrete consisting of dense-graded aggregate and sand, cementitious materials, and water. The use of RCC as a material to construct pavements began in the 1970’s in Canada.

6 GUIDE FOR ROLLER-COMPACTED CONCRETE PAVEMENTS RCC mixtures typically have a lower volume of cementitious materials, coarse aggregates, and water than conventional concrete mixes and a higher volume of fine aggregates, which fill the air voids in the pavement system (Figure 1-5).
Roller-Compacted Concrete RCC is made up of the same ingredients as a conventional concrete mix (cement, water and aggregates), but uses a much drier mix than conventional concrete. The mix is placed with high-density asphalt paving equipment then followed by additional compaction with rollers.
