AN EXPERIMENTAL INVESTIGATION OF THE RESPONSE OF INTERLOCKING CONCRETE BLOCK PAVEMENTS TO SIMULATED TRAFFIC LOADING

This paper reports an experimental evaluation of the behaviour of full-scale interlocking concrete block pavements subjected to simulated traffic loadings. The independent variables studied included the thickness and shape of the paving blocks, the depth of the sand bedding layer and the thickness of the basecourse. Two simulated tyre pressures (600 kpa and 900 kpa) were examined. The dependent variables studied included the permanent and resilient deformations of the pavement surfaces and the distributions of vertical compressive stress within the pavements. The study showed that block pavements responded to traffic loadings in a manner qualitatively similar to conventional flexible pavements. However, it was established that block paving exhibited several significant improvements in performance over comparable thicknesses of conventional pavement. For interlocking blocks the effects of block shapers were concluded to be of minimal importance. (a). (TRRL)
