2.The use of roller-compacted concrete (RCC) originated in Canada during the mid-1970s when dry land log sorting became mandatory for the forest industries of British Columbia. RCC, a durable paving material that carries heavy loads, is now developing as a fast, economical construction method for dams, off-highway pavement projects, heavy-duty parking and storage areas, and as a base for conventional pavement. RCC is a stiff, zero-slump concrete mixture with the consistency of damp gravel comprised of local aggregates or crushed recycled concrete, portland cement, and water. The mixture is placed and roller compacted with the same commonly available equipment used for asphalt pavement construction. The process requires no forms, finishing, surface texturing, or joint sawing and sealing. -PCA
