A Guide for Design and Construction of Roller-Compacted Concrete Pavements.
Abstract
Roller-compacted concrete pavement (RCCP) provides a lower-quality, economical alternative to slipform and fixed-form concrete pavements. It is ideally suited for areas where heavy, low speed vehicles such as tanks or container handlers are the primary users of the pavement. RCCP is constructed by placing a zero-slump portland cement concrete mixture with an asphalt paver and compacting it with several passes of a vibratory roller. By using this construction method, wherein large quantities of concrete can be placed quickly with a minimal amount of labor and equipment, savings of 30 percent over conventional concrete paving methods have been reached. The final RCCP surface is not as smooth as a conventionally constructed concrete pavement, and the surface texture resembles that of an asphaltic concrete pavement surface. Quality control and assurance consist of testing materials going into the concrete, checking the plant calibration regularly, measuring the in situ density of RCCP using a nuclear density gage, checking the smoothness of the finished RCCP with a straight edge, and taking cores to check the pavement strength, density, and thickness. Inspectors at the plant and on the jobsite are vital to ensure that a quality RCCP is being built.
