Tenaris Roller Compacted Concrete

Roller Compacted Concrete (RCC)

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. RCC is similar to what the industry knows as conventional concrete (stone, sand, cement, and water), RCC however, is composed up of different proportions and placing methods. Roller compacted concrete pavement 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 RCC is by first being placed through a high density paver and subsequently compacted by a non-vibratory or vibratory roller. Most of the time, RCC is constructed without formwork, steel reinforcement, or dowels. Making a significant economic impact in those areas for the job at hand.


Soil Cement


Soil cement is a highly compacted mixture of soil/aggregate, cement and water. It is widely used as a low-cost pavement base for roads, residential streets, parking areas, airports, shoulders, and materials-handling and storage areas. Its advantages of great strength and durability combined with low first cost make it the outstanding value in its field. A thin bituminous surface is usually placed on the soil cement to complete the pavement. The family of soil cement pavement products can actually be divided into two main components – each with its own unique contribution to a pavement structure. These components include cement-modified soils (CMS) and cement-treated base (CTB).

Soil Stabilization / Cement-Modified Soil (CMS)


A cement-modified soil (CMS) is a soil material that has been treated with a relatively small proportion of Portland cement–less cement than is required to produce hardened soil cement. The objective of the treatment is to amend undesirable properties of problem soils or substandard materials so that they are suitable for use in construction.

A good foundation is important for any structure, especially pavements. The pavement base provides the thickness and stiffness necessary to carry heavy traffic loads.

Cement-Treated Base (CTB)


Cement-treated base (CTB) is an intimate mixture of aggregate material and/or granular soils combined with measured amounts of Portland cement and water that hardens after compaction and curing to form a durable paving material. A bituminous or Portland cement concrete layer is placed on the CTB to complete the pavement structure. Cement-treated base is widely used as a pavement base for highways, roads, streets, parking areas, airports, and materials handling and storage areas.

Curb & Gutter



Using the latest, most advanced equipment and technology has allowed Rollcon to be extremely versatile, producing curbs and gutters, median barrier walls, retaining walls, and sidewalk with monolithic curb and gutter.
At Rollcon we utilize Gomaco concrete slip form equipment. This equipment can reduce cost, time and can cover thousands of feet a day. It is the most versatile and dependable equipment available today. It allows us to deliver a better, more consistent product and perform larger curb and gutter projects faster.
Using Gomaco equipment along with our highly skilled and trained team, we are able to man multiple jobs at different sites with special requirements on an as-needed basis. This in addition to newly placed Roller Compacted Concrete areas, provides fast turn-key solutions to industrial timelines.

Road Widener/Shoulder Construction


Utilizing specialized equipment such as a road widener allows Rollcon to easily install shoulders on roadways, driveways, and sidewalks with select aggregates, stabilized material or topsoil. The road widener can provide edge protection from water penetration as well as vehicle damage.
The road widener can distribute 20 tons of material in minutes and provide 1-4 feet of shoulder material and 12 inches below grade.
Just another example of Rollcon’s ability to provide fast, efficient, turn-key completed roadways.

Pervious Concrete

pervious samplePervious concrete is a special type of concrete with a high porosity used for concrete flatwork applications that allows water to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. Pervious concrete is made using large aggregates with little to no fine aggregates. Pervious concrete consists of cement, coarse aggregate and water with little to no fine aggregates. The addition of a small amount of sand will increase the strength. The mixture has a water-to-cement ratio of 0.28 to 0.40 with a void content of 15 to 25 percent.

Pervious concrete can be used in areas with light traffic such as parking areas and fire lanes. It is an important application for sustainable construction and is one of many low-impact development techniques used by builders to protect water quality and reduce reliance on retention ponds.The proper utilization of pervious concrete is a recognized Best Management Practice by the U.S. Environmental Protection Agency (EPA) for providing first flush pollution control and stormwater management.
