Comparison of Laser-Based and Sand Patch Measurements of Pavement Surface Macrotexture

Document Type



This study compares the results of two measurement methods for pavement surface macrotexture: the ASTM E965 sand patch volumetric method and the Digital Surface Roughness Meter (DSRM, laser technique) conducted at a total of 13 different paved road sites in metropolitan Clark County, Nevada. Least-squares regression of DSRM-measured mean profile depth (MPD) on sand patch mean texture depth (MTD) was statistically significant (r2=0.95, p
