Surface Texture Gauge

A surface texture gauge is used to measure the texture depth of a road surface, which influences skid resistance, drainage, and overall surface performance. Texture depth is a key parameter in highway safety and durability assessments.

The gauge measures surface irregularities to confirm whether the finished surface meets specification requirements. Results help inform whether further treatment or adjustment is required before reopening to traffic.

Surface texture measurement is standard practice within highways and road maintenance services, and it is often considered alongside dry film thickness (DFT) checks during road marking operations.
