Roller Compacted Concrete (RCC) is a versatile heavy duty paving material used on industrial, commercial and military hardstandings, parking areas and road schemes.
RCC originated in North America and has been used extensively since the 1970’s. It is used where exceptionally heavy trafficking is required and where functionality and fitness for purpose are paramount. The material is laid by paver, as in a cement bound material. We have a number of reference sites in the UK where RCC has been used as the finished pavement for a variety of applications including port work, composting slabs and general storage areas.
Roller Compacted Concrete Company
Roller Compacted Concrete Company can offer you the complete package from pavement design through to installation or a basic mix and lay service.
Roller Compacted Concrete Company links the mixing resources of Sitebatch Technologies with the paving resources of Needham & Cullen Road Services. Both companies have a long, successful history of working on major paving projects, including: Birmingham Northern Relief Road; Chek Lap Kok Airport; Runway 1, Hong Kong and more recently a number of projects in the UK using Roller Compacted Concrete.

Case Study: General Cargo Storage / Container Terminals This project consisted of an area of approximately 26,000m² plus a smaller car parking area. The terminal’s final purpose was for general storage. Originally a reclaimed land area it was laid initially with 400mm chalk to formation level.
Sitebatch proposed the use of Roller Compacted Concrete, a

pavement which is popular in the United States for industrial hardstandings.
As a further modification to the pavement design, the designer decided upon a Cement Bound Material (CBM) layer to replace Type 1 sub-base, this enabled a thinner RCC layer to be placed providing an all round superior pavement.
The chalk was laid to level by a dozer, then rolled and compacted. Secondary aggregates were chosen for the CBM – a blast furnace steel slag used in conjunction with a conditioned ash. Both the CBM and RCC were paver laid with the RCC forming the final running surface. A pneumatic tyred roller (PTR) was used along with a vibratory roller to close the surface of the RCC. The material was cured using a liquid wax membrane. Controlled cracking was induced using a Wacker plate on a 4m x 3m grid pattern.
Sitebatch advised in the sourcing of aggregates and cements.
L. J. Church Laboratories were commissioned to undertake preparatory mix designs and monitored the on site RCC and CBM production. |
