Pavement surface texture greatly contributes to the tire pavement skid resistance. Pavement surface irregularities are continuous from pavement macrotexture to pavement microtexture. Skid resistance is highly dependent on the surface irregularities of individual stone particles used in pavements and upon the larger irregularities of the overall road surface. The surface irregularity of individual particles is referred to as "fine-scale" or "micritexture". "Coursescale" or
