Latest Developments for Roller Compacted Concrete (RCC) in USA

Paper and Presentation by Shane Dunstan from ASCP 3rd Concrete Pavements 2015

Roller Compacted Concrete (RCC) is a no slump concrete that is placed by a high density 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 summarise a recent survey of uses of RCC, types of paving equipment and final surface since 2011 in North America as well as provide a few case studies on local roads, bike trails industrial 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 utilisation of diamond grinding for a smoother finish, are also documented.
