About This Product
The Benkelman Beam is a manual way of measuring how much a flexible road pavement deflects under a wheel load. The tip of the beam is placed between the dual wheels of a loaded truck, and as the truck moves away the pavement rebounds and the dial gauge records the movement, which is magnified by the beam ratio. The deflection reading is used in pavement evaluation and overlay design. The beam is used in highway engineering practice and in civil engineering training. Schools, colleges and distributors in Bolivia, Somalia, Barbados, Latvia, Kuwait and Slovenia can source the Benkelman Beam from School Lab Equipment India.
