DEVELOPMENT OF ROLLER COMPACTED CONCRETE - A NEW PAVING TECHNIQUE

The paper evaluates the use of roller compacted concrete pavement (rccp); a relatively new type of rigid pavement system that utilises a construction technique similar to that of asphaltic concrete pavement construction to provide a strong as well as economical pavement. It involves laydown and compaction of zero slump concrete mixture and potential exist to save one-fifth the cost of conventional concrete pavement (ccp) construction. Cost saving achieved by using rccp versus ccp is reached by placing large volume of concrete in a relatively short period of time with minimal labour and equipment, use of fly-ash as a part replacement of either cement or sand and sometimes both (with some sacrifices in early strength), since a greater percentage of fines is usually allowed in rccp than in ccp (to enhance workability). The saving is further accentuated by decreasing cement content on account of lower w/c ratio.
