Benkelman beam
BENKELMAN BEAM
The Benkelman Beam measures the deformation of a material under stress. This equipment is used for the two following test:
• The plate test measures the static deformation EV1/EV2 (roads) and Westergard deformation (platforms). The
Benkelman beam mesure the formation level bearing capacity by applying a load on the plate to the material with the loading device.
• Standard Benkelman Beam tests measures pavement deflection in response to a static load. Measurement is made by placing the tip of the beam between the dual tires of a loaded truck and measuring the pavement surface rebound as the truck is moved away.

MATERIAL
For the deflection test, the beam is used alone.For the plate test, a loading device and aluminum plate are necessary.
