The Sand Patch Equipment is a measurement device used to determine the macrotexture depth of road and airfield surfaces. It utilizes the volumetric patch technique to evaluate the roughness and smoothness of the surface. Primarily used to assess the surface texture of asphalt and concrete pavements, it helps analyze factors affecting surface drainage and tire grip. The equipment is widely used in road construction and maintenance, airfield runways, and similar infrastructure projects due to its simplicity, portability, and ability to provide reliable results.
