Abstract Details

2009, Master of Science, Ohio State University, Civil Engineering.
This study investigates and compares mean profile depth (MPD) measurements from three laser-based macrotexture measuring devices, namely a Dynatest laser profiler, a Circular Texture Meter, 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 are researched. The effect of macrotexture on surface friction is also investigated using a Dynamic Friction Tester. The study uses sand patch test 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 Portland cement concrete samples of varying finish, as well as other common, manufactured, textured samples. Analysis of the data shows that the MPD obtained from the Ames Laser Texture Scanner has the highest correlation to the MTD measurements determined using the sand patch test. It is also determined that the MPD values taken by the laser profiler decreased as the speed at which the sample was traveling increased. A new correlation for predicting MTD from laser profiler MPD is developed through laboratory testing. Additionally, it is found that material type had an effect on the laser MPD values.
