MODIFIED JOINT DESIGN FOR CONCRETE ROADS

The author summarises the current design requirements of joints in concrete roads and draws attention to their disadvantages. Details are given of a proposed modified joint design: the device is a steel plate into which a series of holes have been punched. One side of the joint has its projections normal to the surface of the plate, whilst the other side has its projections bent over so that, when concreted in, they form an anchor between the plate and the concrete. The advantages of the new design are summarised: it would sever the continous slab into discrete lengths, eliminate the need for joint sealing, give adequate load transfer across a joint, involve relatively low installation costs, and probably eliminate the need for a separating membrane between slab and base. /TRRL/
