The study investigated the texture depth, skidding resistance and
roughness index of various bituminous pavement surfaces in Johor,
Malaysia. 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 surface
roughness of the road surface is determined by using the Australian
walking profilometer. The surface roughness of road constitutes the
comfort and safety the pavement provides to the user.
