In order to utilise fully the strength of reinforcement material while transferring load and forces via soil or aggregate to the reinforcement, a correct assessment of the soil/ reinforcement frictional relationship is essential. The frictional properties can be assessed by means of a shear box which is modified either to conduct a 'Modified Shear Test' or ' Pullout Test'.
These are 60x60x25 mm assemblies. Can be used for soils with D85 not greater than 4.75 mm. These apparatus are to be fitted in conventional Direct Shear Test Frame
Note: The Direct Shear apparatus is to be ordered separately.
