BENKELMAN BEAM
Description :
The ability of a pavement to flex without failure when subjected to
loading is an important feature of any construction designed to carry
moving loads. Deflection can be measured by using a long beam
resting on the pavement surface at one end and balanced near its
centre point. By stabilising the opposite end of the beam using a
suitable load e.g a vehicle, small deflections caused by loads applied
adjacent to the free end are magnified and can be read from a
