A laminate 3 is used which has on the bottom a geotextile fabric 2 with the mesh structure 4 on the top. The fabric 2 is adhered to the ground or road base 1 by spraying or spreading a bituminous liquid onto the ground and laying on the laminate and applying further adhesive to the top of the laminate 3; the asphalt 5 is then placed and rolled. The laminate 3 is formed of a square or rectangular mesh structure 4 which has oriented strands connected at junctions which are thicker than the strands and have low-orientated or unorientated nodules. On one side the surface of the nodules are melted and the fabric 2 is pressed into the nodules so that the plastics material of the nodules envelopes some of the fibres or filaments of the fabric 2 to form a mechanical bond. In this way, the oriented strands stand proud of the fabric 2, to enable the asphalt aggregate to penetrate into the meshes and interlock with the strands.
