2100763 9212865 PCTABS00014 A mat comprises a membrane (1) which is moulded from a high-wear-resistant natural or synthetic rubber material, so as to form integrated projecting studs, two on each side. The studs are positioned in pairs directly above one another (as shown in figure 2) and each stud has a conical base part (3) and a projecting portion (4) of circular cross-section. When such a mat is laid on soft ground, the studs (2) on the lower side will grip into the ground whilst the studs on the upper side will provide a firm surface for the vehicle wheel. The gaps between the studs (2), on the upper surface, allow for the free flow of fluid material (mud, snow, sand, etc.) as the wheel presses down on the studs (2).
