The Benkelman beam measures the deformation of a materiel under stress. This equipment is used for the two following tests:

  • The plate loading test according to NF P 94-117-1
  • The flexible pavement deflection testing according to standard NF P 98-200-8.

For the deflection test, the beam is used alone. The beam is available as a high-end model or as an economical model.

Plate testing requires an aluminium plate and a loading kit:

  • The aluminium plate manufactured by Apageo is ribbed and has 2 handles for easy handling
  • Different models of loading units are available to suit all your needs: Manual hydraulic (with electric or pneumatic pump option) for easy testing or manual mechanical for more limited budgets.
