CUTTING PAVEMENT COSTS

Roller-compacted concrete pavement (RCCP) can save up to 30% of construction costs. Although RCCP can never equal the quality of conventional concrete pavement, it is well suited for many applications. Construction involves laying and compacting a relatively stiff portland cement concrete mixture to form a durable wearing surface for operating vehicles. A new paver has been used which is equipped with a vibrating, double tamping screed capable of compacting RCCP to more than 90% of its theoretical maximum density. Some compromises to be expected with RCCP involve surface characteristics. The practice of letting RCCP crack naturally as it shrinks during curing saves the costs of sawing joints. RCCP is also prone to ravelling. RCCP materials selection and mixture proportions are discussed, as well as the use of aggregates. The subgrade and base course for RCCP, compaction with a vibratory roller, moisture curing, and its sensitivity to changes in mixture proportion or construction procedure are also discussed. Potential applications for RCCP include low volume roads, especially those carrying a large percentage of heavy trucks.
