CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS

Continuously reinforced concrete pavements (CRCPS) were evolved in a desire to eliminate transverse movement joints from concrete pavements. This form of construction has been widely used in the USA and Belgium and the behaviour of CRCP in these two countries is outlined. Factors affecting the performance of CRCP are examined, together with some of the theoretical studies which assist in assessing their behaviour and in the design of the pavements, especially their steel content. Reasons for the optimum spacing of transverse cracks are given together with the need for terminal treatments of CRCP. Construction is described insofar as it is different from the paving of conventional joined pavements. Early results from British CRCPS are given, although it is as yet too early to reach any conclusions from these trials. Use of CRCPS as overlays to concrete and flexible pavemnets is described together with the use of continuously reinforced concrete as a roadbase (CRCB). Maintenance and repair differ from that necessary for concrete pavements in some aspects which are defined and the economics of CRCP are briefly discussed. Areas where further research is desirable are outlined. (Author/TRRL)
