The determination of the skidding resistance of a bituminous pavement surface depends on the texture depth of the road surface. The texture depth is a measure of the macrotexture of the pavement surface, which is the coarse component of the surface aggregate and determine by sand patch test (SPT). While the microtexture, which is the measure of the aggregate interstices referred to as the resistance to polishing (PSV) of the aggregate, is determined by the British pendulum test ( PTV).The roughness of the road surface is a determining factor for the smoothness of the road surface, and was determined by using the walking profilometer. The study was conducted on jalan Tebrau, jalan Pontian and Batu pahad, 180 test points were investigated for the three tests. This study is aim at determining the minimum skidding resistance, texture depth, and roughness index of various bituminous road surfaces, and there correlation. The results obtained from the study shows a fair correlation between the texture depth and the roughness index of the chipseal road surfaces. But the general trend is that the higher the texture depth (TD), the higher the roughness index (IRI) and the skid resistance (SR), except with the new ACW 14 where at high SR the IRI is low, as the SR depends on the microtexture.
