A study of the performance of blockpaving under traffic using a heavy vehicle simulator

In May 1979, a study of the performance of interlocking concrete block pavements was initiated by the National Institute for Transport and Road Research, using a heavy vehicle simulator (hvs). The performance of a variety of concrete paving blocks available in South Africa is being studied by subjecting full scale test pavements to accelerated trafficking. Factors being investigated include the shape and thickness of the paving blocks, the strength of the blocks and the laying pattern. The purpose of this paper is to report the results that have so far been obtained in this study although the study is not yet complete. These results show that, under traffic, block pavements tend to achieve an interlocked condition beyond which the accumulation of deformation is extremely slow. Once interlock is achieved increases in the magnitudes or numbers of wheel loads applied to the pavement have little effect on the pavement deformation. The ability of a pavement to interlock or to withstand a given level of wheel load depends on the shape of the paving block. However, the compressive and flexural strengths of the concrete blocks do not influence the performance of block pavements within the range from 25 to 57 mpa.
