TBTLWD-1GW handheld light weight deflectometer is used to determine the deflection of subgrade under dynamic loading, further to evaluate the bearing capacity and deformation of subgrade. It is suitable to inspect construction foundation for railways, highways, airports, urban transportation, ports, docks and industrial & civil buildings under dynamic loading, especially suitable for inspecting narrow areas such as road-bridge (culvert) transition sections and road berm, or subgrage for existing railway or road. It can quickly measure the dynamic deformation modulus Evd value.
