Roller Compacted Concrete

Overview
Roller compacted concrete (RCC) is a stiff, zero-slump concrete mixture comprised of coarse and fine aggregates, Portland cement, fly ash, and water. Using our vibratory roller equipment and screed technologies, we can place and roller compact RCC pavement in a manner similar to our asphalt pavement construction solutions. During this process, concrete compaction begins immediately at the paver and continues throughout roller stages until the pavement meets density requirements.

In general, Roller Pave RCC pavement is constructed without joints and does not require forms, finishing, surface texturing, joint sawing, or sealing. It also does not contain dowels or steel reinforcing.

Benefits
Because of its low water/cement ratio, RCC pavement typically has high strengths similar to, or even greater than, conventional concrete. Its high strength properties, combined with ease of construction and high production rate, often make this paving option more economical than a flexible pavement. Additionally, more than twenty years of exposure in various locations throughout the country have demonstrated that RCC pavement delivers adequate resistance to freezing and thawing with little or no maintenance. RCC offers:

– Fast Construction
– High Load-Carrying Ability
– Rut Elimination
– Spanning of Weak Sub-Grades
– Early Strength Gains
– Durability
– Low Maintenance and Superior Life Cycle Costs
– Economical Paving

Considerations
RCC can be a viable solution for a variety of industrial, agricultural, road/shoulder, warehouse, and heavy-duty pavement requirements, or as a base for conventional pavement. Grimes Asphalt and Paving works closely with each customer to analyze its needs and provide suggestions for the most effective pavement options.

Sample project applications include:
