- Recent Advances and Uses of RCC in the United States
Corey Zollinger, P.E., Director of Paving Solutions, CEMEX USA
Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. Recently, RCC has been used with good success on Interstate highway shoulders, subdivision streets and collector/arterial roads. RCC is now being used in conjunction with diamond grinding the surface allowing it to be placed as smooth as asphalt or conventional concrete pavements at a lower initial cost. Since RCC is usually placed with 1 lift, reconstruction of existing pavements proceeds much faster than other alternatives. Recent developments with mix design, aggregate selection, etc will also be covered.
