Benkelman Beam Apparatus

Benkelman Beam Apparatus: MTBA -02

Benkelman beam is a very simple apparatus and it is commonly used for measuring the surface deflection of a pavement under standard loading conditions. A schematic arrangement of the Benkelman beam (Refer Slide Time: 11:11). It is cut at several places because its full length cannot be shown in sketch. This is the probe point which would be resting on a pavement surface at a point at which we are trying to measure the deflection. As you can see here since it is very long its extended portion is connected here by nuts and bolts so it can be dismantled and then for ease of carrying and other convenience it can be carried in two different parts but when we actually use it for deflection measurement we will connect them together so the full length of the beam is going to be attained.
