Component

Roller-compacted concrete (RCC) is a stiff mixture of aggregate, cementitious materials, and water with zero slump. RCC is consolidated or compacted in the fresh state using a roller with or without vibration. RCC is typically placed with asphalt paving equipment in 4 to 8-inch thicknesses per layer for pavement application. RCC has gained the attention of the paving industry in recent years because of its history of low-cost, rapid construction; satisfactory early and ultimate strengths; and durable performance. The Virginia Department of Transportation conducted a laboratory study in order to develop guidelines for its use in the field. RCC mixtures were successfully produced using locally available materials, and their properties were measured. These mixtures achieved a compressive strength around 5,000 psi in 28 days and had properties similar to those of conventional hydraulic cement concrete in terms of compressive strength, modulus of elasticity, modulus of rupture, splitting tensile strength, permeability, and resistance to cycles of freezing and thawing.
