RESEARCH INTO THE PERFORMANCE OF INTERLOCKING PAVER PAVEMENTS
The increase in the popularity of pavers as a road surfacing material has brought about the need to understand better the performance, under traffic loading, of pavements surfaced with pavers. One of the unique characteristics of the behaviour of pavers is the structural mechanics of interlock which causes the surface to adopt a mode of behaviour similar to that of conventional flexible materials. The functional details of interlock were explained theoretically in previous research by the authors. Their resolution of the structural mechanics underpinning the behaviour of pavers leads to two important questions. How does paver interlock affect entire pavement performance under combinations of various load applications and material properties? And how can the structural performance of flexibly bedded units be integrated into the day-to-day design process? This paper seeks to resolve these questions by using an axi-symmetrical finite element model in conjunction with previously reported theoretical research to examine the behaviour of a range of pavements surfaced with pavers.
