Rcc compaction roller

Properties of hardened RCC can be similar to those of conventionally placed concrete.

Speed of Construction Perhaps the biggest benefit of Roller Compacted Concrete pavement is that it can be constructed more quickly and cost-effectively than conventional concrete or most asphalt pavements. Roller Compacted Concrete is placed with conventional or high-density asphalt-type paving equipment and compacted with rollers, eliminating the need for forming and finishing.

In most cases, Roller Compacted Concrete can be competed in one pass. Extremely heavy-duty pavements requiring thicknesses greater than 10 inches may require two lifts.

Because of its density and compaction, Roller Compacted Concrete can achieve sufficient load carrying capacity quickly and has, in some instances, been open to traffic within 24 hours after placement Durability Roller Compacted Concrete is a rigid pavement which will easily withstand the load form repetitive traffic.

Because it can more evenly carry heavy loads, Roller Compacted Concrete will not rut from heavy axle loads, nor will it shove or tear from turning or braking vehicles. Additionally, Roller Compacted Concrete has all of the durability of conventional concrete pavement including resistance to fuels, oils, solvents and other fluids, and the ability to withstand the extremes of summer heat and winter cold.

Low Maintenance Similar to conventional concrete, Roller Compacted Concrete has fewer repairs over its service life.

There is no seal coating or resurfacing required. Historically, Roller Compacted Concrete has been comparable in cost to asphalt pavement. Sustainability Roller Compacted Concrete pavements are environmentally friendly. Supplementary cementitious materials such as fly ash and ground granulated blast furnace slag can be used, reducing the amount of Portland cement and thus lowering the embodied energy of an Roller Compacted Concrete mix.

The lighter color of Roller Compacted Concrete also means less heat is absorbed, resulting in cooler communities. Utilizing a lighter colored pavement such as Roller Compacted Concrete can reduce ambient air temperatures by as much as degrees.As evidence, ASTM International is formalizing a method for making a cylindrical specimen of RCC in a gyratory compactor.

Roller compacted concrete (RCC) is a tough, durable type of concrete pavement that is well suited for heavy industrial applications, as well as low-speed roads and arterial roads. Roller compacted concrete draws its name from the construction practices used to place and finish the material. 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. Roller-compacted concrete is a stiff, dry concrete mix that has a low paste content and is placed and compacted using a roller, usually a ton vibratory roller. In pavement construction, the process is similar to that for an asphalt pavement.

Test Method for Preparation, Compaction and Density Determination of Roller-Compacted Concrete Specimens by means of the Superpave Gyratory Compactor is being developed by Subcommittee C on Roller-Compacted Concrete.

Better Roads, 04 January Tom Kuennen With its placement and quick-set advantages, the use of roller compacted concrete is gaining fresh energy among contractors and road agencies.

“RCC is a concrete pavement formed from a no-slump mixture, and is Continue reading →. Roller Compacted Concrete (RCC) is a relatively stiff, zero-slump concrete mixture with the consistency of damp gravel and compressive strengths greater than 4, psi.


RCC can be made using local materials, aggregates or crushed recycled concrete, Portland cement and/or fly ash, and water. PUBLIC SERVICE DEPARTMENT TRANSPORTATION DIVISION SUPPLEMENTAL SPECIFICATION ROLLER COMPACTED CONCRETE PAVEMENTS (RCC) February 17, production and construction of Roller Compacted Concrete (RCC) pavement for City streets.
