This paper investigates and compares mean profile depth (MPD) measurements from two
laser-based macrotexture measuring devices, namely a laser profiler and an Ames Laser
Texture Scanner, to mean texture depth (MTD) results from volumetric sand patch tests. In
addition, the effects of speed and material type on the MPD results for the profiler were also
researched. The study used data obtained from field testing at three sites, each with a variety
of pavement types, and laboratory testing on various types of Hot Mix Asphalt (HMA) and …
