Our professional asphalt depth gauge is an essential measuring instrument for paving crews and engineering inspectors, built to simplify accurate asphalt thickness control during all road construction jobs. Equipped with a probe featuring 8 preset depth settings spanning from 1-7/8" to 8-7/8", this tool lets you quickly set your required depth; just insert the probe vertically into hot asphalt to instantly measure the asphalt layer and guarantee evenly laid pavement every time. Boasting a total length of 31 inches, it fully meets standard road paving thickness requirements and works seamlessly for highways, municipal roads, residential areas, and parking lot construction projects. Its practical detachable design allows effortless carrying and storage, enabling you to take reliable thickness measurements anytime and anywhere on-site to maintain consistent pavement thickness. Constructed from high-hardness metal, this depth gauge delivers excellent bending resistance and can withstand prolonged contact with high-temperature hot asphalt without deformation, while its smooth surface allows you to easily wipe away asphalt residue for an extended service life. Designed for straightforward, efficient operation, simply lay the base completely flat on the ground, slide in the probe, secure it with the locking bolt, and pull it out to get steady, deviation-free readings; the ergonomic T-shaped handle also reduces hand strain to deliver comfortable, labor-saving use during long hours of on-site inspection work.
