Paper and Presentation by Corey Zollinger, Recent Advances and Uses of Roller Compacted Concrete for Pavement Construction in the United States from ASCP 5th Concrete Pavements Conference 2019
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. This paper will summarize a recent survey of uses of RCC, types of paving equipment and final surface since 2011 with a focus on the past 3 years in the United States as well as provide a few case studies on recent projects. The paper documents many of the benefits of using RCC on these types of projects such as speed of installation and traffic opening. Recent advances in mix design with admixtures, aggregate selection, as well as utilization of trowelling for a more aesthetically pleasing finish are also documented.
