This Technical Specification specifies laboratory test methods to establish the effective shear parameter for soils within the scope of the geotechnical investigations according to ENV 1997 parts 1 and 2.The test method consists of placing the test specimen in the direct shear device, applying a pre-determined normal stress, providing for draining (and wetting if required) of the test specimen, or both, consolidating the specimen under normal stress, unlocking the frames that hold the specimen, and displacing one frame horizontally with respect to the other at a constant rate of shear-deformation and measuring the shearing force, and horizontal displacement
