IS: 2720 (Part 13), ASTM D 3080 The Direct Shear test is carried out with an apparatus consisting of a square or circular box divided into two halves. The specimen, contained in the box, is subjected to a constant normal load while an increasing horizontal force is applied to one of the sections of the shear box. This force causes a shear failure along the junction between the box sections. The shear force and the normal load are measured directly. The rate of strain is adjusted by the speed of the horizontal force applied. The loading unit has V-strips on which the shear box housing rests. The precalibrated load yoke with direct and lever system for applying normal load of 8 kg/cm2 capacity, fixtures, for proving ring brackets, for holding consolidation and strain dial gauges and lead screw for application of shear stress SHIVAM offers the following models: SSO-1012 Direct Shear apparatus, 2 KN Manual IS: 11229 - 1985, 2720 (Part 13) - 1986  Type of Shear Measurement:  Direct/Residual Operation: Manual Specimen Size: 60 x 60 x 25 mm SSO-1013 Direct Shear apparatus, 2 KN IS: 11229 - 1985, 2720 (Part 13) - 1986  Type of Shear Measurement:  Direct/Residual Operation: Motorised Rates of Strain (mm/min): 1.25, Specimen Size: 60 x 60 x 25 mm  Power Specifications: 230 V, 50 Hz, Single Phase, AC supply SSO-1013D Direct Shear apparatus, 2 KN IS: 11229 - 1985, 2720 (Part 13) - 1986  Type of Shear Measurement: Direct/Residual Operation: Motorised  Read Out: Digital  Rates of Strain (mm/min) : 1.25, Specimen Size: 60 x 60 x 25 mm  Power Specifications: 230 V, 50 Hz, Single Phase, AC supply SSO-1014 Direct Shear apparatus, 2 KN, 12 Speed IS: 11229 - 1985, 2720 (Part 13) - 1986  Type of Shear Measurement:  Direct/Residual Operation: Motorised  Rates of Strain (mm/min) : 1.25, 0.625, 0.25, 0.125, 0.05, 0.025, 0.01, 0.005, 0.002, 0.001, 0.0004, 0.0002 Specimen Size: 60 x 60 x 25 mm  Power Specifications: 230 V, 50 Hz, Single Phase, AC supply SSO-1014D Direct Shear apparatus, 2 KN IS: 11229 - 1985, 2720 (Part 13) - 1986  Same as SSO-1014  but read out is Digital

The CBR test is used for determining the relative bearing ratio and expansion characteristics under known surcharge weights of base, sub-base and sub grade soils for the design of roads, pavements and runways. Tests can be conducted on all types of soils including sand, gravel and washed stone (passing through 20 mm IS Sieve). The CBR test is used extensively in selection of materials and control of sub grades. The procedure consists of loading soil with a circular piston, 50 mm dia face and maintaining a penetration rate of 1.25 mm/min. The load is noted and the results of test on natural or recompacted soils, in soaked and unsoaked conditions, can be compared with standard test results.

This apparatus, mounted on a rolled steel joist cantilevered from the back of the truck or fitted to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiently. This method of testing in-situ, using piston penetration, is useful for determining the load carrying capacity in the field, when the in-place density and water contents are such that the degree of saturation is 80 % or greater, when the material is coarse grained and cohesion less so that it is not affected by changes in the water content and when the material has been in place. It consists of: Loading Jack  with U-bracket, capacity 50 kN (5, 000 kgf). This is specially designed for use with Field CBR test apparatus. It consists of a hand operated, two speed, screw jack fitted with a U-bracket. A hexagonal adapter is provided to fix a proving ring. A thrust bar, which passes through the U-bracket, is screwed on to a proving ring (supplied at extra cost) which protects the proving ring when the loading is eccentric. Swivel Head  Swivel Head Penetration Piston  50 mm dia threaded at the upper end, to connect to the various lengths of extension sleeves, through a connector Extension Set  consisting of 1 length of 5 cm, 2 lengths of 10 cm, 1 length of 30 cm, 1 length of 50 cm and a length of 100 cm used as spacers between the proving ring and penetration piston.

IS:2720 (Part 7), 10077, ASTM D 427, BS:1377, AASHO T 92 The Shrinkage Limit of a soil is defined as the moisture content at which any further reduction of moisture will not cause volume reduction. The shrinkage of clayey soil can be very significant. A fully saturated soil specimen is allowed to dry in free air and its volume is measured repeatedly by immersing in a mercury bath. From the data obtained from this test, Shrinkage Limit, Shrinkage Ratio, Shrinkage Index and Volumetric Shrinkage can be calculated. The choice of puddle clay materials is often governed by the results obtained from this test.
