The paving of RCC is quite similar to paving asphalt and is done using asphalt pavers. These pavers are usually attached with extra screed to obtain better compaction during paving. Conventional concrete pavers can also be used either by lifting the needle vibrators or by removing them temporarily during RCC paving. With an assured and a continuous supply of concrete, the paving speed can be kept slightly higher than conventional concrete paving. The material is so stiff that one can stand on freshly paved RCC without damaging the pavement.
Immediately after paving, the concrete is compacted using vibratory drum rollers or pneumatic rollers. The roll-pass chart is developed during the trial patch construction and is used for guiding the compaction effort during actual construction. The density is then monitored using a nuclear density gauge or any other suitable method of measuring in situ density. Refer to Figure for laying and compaction operations.
