Highway Surveys
Highway pavement and bridge deck investigation from a vehicle-mounted array.
Highway GPR survey from Corvus is part of our large-scale gpr service. Highway surveys with array GPR give pavement layer thickness, bridge deck condition, and subsurface anomaly mapping at traffic speeds — turning a long manual job into one that fits in a single possession.
Built around the question being asked.
A vehicle-towed or pushed array surveys the site in lanes. Multiple frequencies capture both shallow services and deeper features. Data is processed into depth slices and combined with locator and topographic data to produce a single accurate plan.
For highway surveys specifically, the brief drives the choice of frequency, density, and reporting style. We quote a method that fits your access window, your accuracy requirement, and the downstream use of the data.
