Roller-compacted concrete is a stiff, dry concrete mix that has a low paste content and is placed and compacted using a roller, usually a 10-ton vibratory roller. In pavement construction, the process is similar to that for an asphalt pavement. RCC mixes are used in a variety of heavy-duty applications at logging yards, loading docks, intermodal port facilities, large parking areas and dams.…, ASTM WK33682, Test Method for Preparation, Compaction and Density Determination of Roller-Compacted Concrete Specimens by Means of the Gyratory Compactor, According to Stacy G.
