Applications:
- The frictional properties is assessed by means of a shear box, which is modified either to conduct a 'Modified Shear Test' or 'Pullout Test'. In the former test, reinforcement material is placed and clamped in the plane of shear with soil above the fabric, whereas in the latter test, the fabric placed between the top and bottom shear boxes, is covered on both sides with soil and is then pulled out to evaluate the frictional resistance. This interface friction measurement apparatus has been specially designed to evaluate both 'frictional' as well as 'pull out resistance' of soil reinforcing materials at a shear rate and drainage condition as desired by the designer.
Details:
- These are 60 x 60 x 25 mm assemblies, which 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.
