Abstract

Asphalt paving blocks have been known in some places around the world, but there have been very limited research being conducted to assess the influence of block thickness on the structural performance of asphalt paving blocks. This study describes the experimental study to evaluate the performance and properties of asphalt paving blocks placed with different block thicknesses i.e., 70, 80 and 90 mm, respectively. A number of 250 asphalt paving blocks was produced and examined in the laboratory to determine the density, air voids, the compressive load and the rut depth and displacement occurred in the surface of asphalt paving block. The results exhibited that the resistance of asphalt paving block to static loading increased as the block thickness increased. Moreover, the elastic deformation was affected significantly by increasing the block thickness. Meanwhile, the displacement of asphalt block from the pavement was slightly influenced by the block thickness.
