The document discusses roller compacted concrete (RCC), including what it is, where it has been used, and the construction process. It provides examples of RCC projects in Ohio, South Carolina, Georgia, and at Ohio State University. The construction process involves central mix or continuous flow pugmill mixing, placement with asphalt pavers, and compaction with vibratory rollers. A bid tab is presented comparing costs for a project using asphalt or RCC pavement. RCC has significantly lower 75-year maintenance costs compared to asphalt.
