Component

Roller compacted concrete (RCC) pavements can be an economically attractive solution for streets and roads up to and including the major arterial category. Generally, RCC composite pavements have performed well in a variety of applications. In areas such as Quebec, Canada, and Columbus, Ohio, they have become an important solution for new street and road construction as well as pavement rehabilitation. However, in many areas, there is little experience with use of RCC for these applications. There is a need for planning tools for owners, contractors, and concrete suppliers. This paper addresses planning considerations and design tools for determining whether an RCC pavement is an economically feasible solution for a given application. Methods for designing RCC pavements for streets and roads are reviewed. Construction considerations are also addressed. Some case studies are presented, including comparison of equivalent designs between RCC and flexible pavements. Design and construction of RCC composite pavements remains as much of an art as a science, and there are some important considerations for designers, contractors, material suppliers, and owners.
