Tarmac Roller Compacted Concrete (RCC) is a durable and fast construction solution for heavy duty pavements. Roller Compacted Concrete gets its name from the method of construction used to place the material. Just like asphalt, it is laid by paver and then roller compacted. RCC is designed to a target grading and low water content.

The RCC Pavement Council is a volunteer industry trade association representing the interest of those involved with the construction of Roller Compacted Concrete Pavements. The RCC Pavement Council supports Research and Promotion to improve the quality of RCC pavements and expand their use in a responsible and sustainable manner.
Roller-Compacted Concrete (RCC) is a no-slump concrete that is placed using asphalt concrete paving machines and compacted by vibratory rollers. The RCC pavements are lower cost alternative to conventional jointed concrete pavements and generally provide
The finished product is referred to as roller-compacted concrete (RCC). A zero-slump concrete mix, RCC doesn't need formwork, dowels, or rebar, and it requires minimal finishing. But one element of traditional concrete paving shouldn't be abandoned—diamond grinding the surface for smoothness. While it was once common to overlay RCC with ...
machines for mechanized construction of concrete pavements is largely exceeded by those used for asphalt paving, mainly finishers and rollers. Roller Compacted Concrete (RCC) is a hybrid technique allowing the use of asphalt equipment to achieve a pavement featuring properties (strength, durability) similar to those of vi - brated concrete ...
3D Technologies for Milling, Paving, & Compaction The evolution of machine control specific to the paving industry is allowing contractors to build roads more accurately than ever before. This use of technology in various road building applications provides many …
Introduction of Roller. Most construction sites require an anchored ground to perform. One of the principal common kinds of compaction equipment is the road roller. Rollers are a sort of construction plant utilized for compacting stuff like soil, gravel, sand, road surfaces, etc.. The material is compacted by vibration, impact loading, kneading, & direct pressure.
Find out more about roller compacted concrete and the benefits over asphalt in road and concrete pavement construction.
Types of Rollers use soil compaction, earth compaction Equipment in construction Earth compaction equipement. Rollers are machines that use in construction work in civil engineering. A roller is a costly machine but they give a good result on construction work. They take a …
Roller unit consist of two equal diameter counter rotating roller through which powder is passed and get compacted. Rollers create pressure on powder material and converts into compacted ribbon. Two types of roller compactors are available according the nature of the gap between two rollers, those two types are roller
by roller compaction for a wide range of produ cts and without the need of additional ingredients such as binders, moisture or lubricants. Furthermore, dry granulation by roller compaction is used to eliminate dust, increase the bulk density, reduce the storage volume, improve handling and manipulate the dissolution properties.
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.
SaintyCo Roll Compactors are cGMP and CE compliant machines that guarantee uniform particle distribution and increased bulk density. With our best market prices, SaintyCo Roll Compactors are available for both R&D and large scale dry granulation.

- 3 - DEFINITION "Roller-Compacted Concrete (RCC) is a no-slump concrete that is placed with asphalt type pavers and compacted by vibratory rollers" Zero slump (consistency of damp dense gravel) No forms or finishing No reinforcing steel High production Asphalt paving equipment Consolidated with vibratory rollers Concrete placed in a different way!
They are also suitable for roller-compacted concrete projects. These machines provide high-frequency (about 4000 vpm), low-amplitude vibrations generated by eccentric shafts within the drums or mounted on the frame. Padded rollers, also known as trench or sheepsfoot rollers, are designed for compacting cohesive soils and are often used in the ...
These rollers are generally pulled or towed behind any heavy machine or a tractor. With little kneading action on compaction work, the grid design on the cylinder drum produces a high contact pressure and on well-graded, coarse soils, weathered rocks and for sub-grade and sub-base road constructions, they are most suitable.
Rollcon is the premier roller compacted concrete (RCC) contractor in the United States. Public and private sector clients across the country choose our roller compacted concrete due to its superior speed of construction, high early strength, and lower lifecycle cost compared to asphalt and traditional concrete paving.
Cometech provide complete series of adhesion test equipment, from specimen cutting production, roller compacted, initial adhesion to holding power, peeling tests. Machine production all conform to PSTC, ASTM standards.
The manually operated milling bars push material – either in roller compacted ribbon or tablet piece form – through the screens in the milling chamber, with fully processed granules collected in a drawer. The overall design emphasizes ease of use with fast and simple fitting and cleaning of all components.

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.
