RCC takes its name from the method used to build it. Mixing of Roller-compacted concrete. A Roller-compacted concrete (RCC) mixing facility, such as a pug mill, tilt drum, or dry batch ready-mixed plant, must have the efficiency to evenly disperse the relatively small amount of water present in the stiff, dry mix which resembles damp gravel.Transport of Roller-compacted concrete

Whereas, a roller-compacted concrete pavement built to replace a failed pavement on a major route may require reaching 2,500 psi compressive strength and be opened for traffic within one or two days from placement. Different mixes of roller-compacted concrete can be designed to meet the different requirements of the two applications.
