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. Williams, Ph.D., director, Center for Training Transportation Professionals at the University of Arkansas, and a C09.45 member, notes that the Superpave gyratory compactor was developed during the 1980s as a means to provide a laboratory simulation of the compactive effort imparted by rollers on an asphalt mat. Roller-compacted concrete is compacted using the same type of…, ASTM WK41101, Practice for Molding Roller-Compacted Concrete in Beam Molds Using a Vibrating Hammer, Once approved, ASTM WK41101 will be used to consolidate RCC into beam molds with established flexural strengths. This is important because RCC is gaining use as a pavement for roads, shoulders and streets and all pavements need flexural strength data for design purposes. , ASTM WK42461, Test Method for Density (Unit Weight) and Air Content (Pressure Method) of Freshly Mixed Roller-Compacted Concrete, ASTM WK42461 covers the determination of density and air content of freshly mixed concrete. WK42461 will be used in the design of roller-compacted concrete mixtures and to aid in controlling the quality of those mixtures during RCC construction.
