Bromhead Ring Shear Apparatus

Bromhead Ring Shear Apparatus

Description of Bromhead Ring Shear Apparatus

The apparatus tests the residual shear strength of remoulded soil samples. The main advantage of this method compared to direct shear test consists in the continuous shear with a constant area during all the test long. This method allows us to recreate in the laboratory exactly the field conditions, giving very accurate residual shear strength values. The sample is loaded vertically between two porous stones by means of a counter balance 10:1 ratio lever loading system.
