Major Equipments

Triaxial Test

Standard : BS 1377:7, 8 / ASTM D2850, D4767/ NF P94 070, P94 074

To design foundations, embankments and other soil structures, Geotechnical Engineers require methods of assessing the mechanical properties of soils (Mohr envelope: UU and CU test).

This machine has been designed for use both at field and in the laboratory where it is necessary to perform mechanical properties of soils. Compression tester, with 50kN max. capacity and lowest and highest speed corresponding to 0,00001 and 9,99999 mm per minute.

Direct Shear Test

Standard : ASTM D3080, AASHTO T 236

Shear strength is defined as the resistance of a soil to the induced shear strain. Shear strength is not a fundamental property in soils as it depends on the in-situ conditions, such as density, moisture, stress state etc.

Shear Box apparatus is designed for carrying out tests on soil specimens of 60 mm and 20 mm high.

The strength parameters obtained from a direct shear test are the cohesion (c) and angle of friction (φ). In densely packed granular soils, two distinct values for these parameters exist, namely Peak or Maximum and Residual or Constant.

One-Dimensional Consolidation Test

Standard : ASTM D2435, ASTM D4546, AASHTO T216, ASTM D3877, BS 1377-5

To Determine the magnitude and rate of consolidation of soil when it is restrained laterally and drained axially while subjected to incrementally applied controlled-stress loading.

CBR Test

Standard : BS 1377, 1924; EN 13286-47; ASTM D1883; AASHTO T193

To determine the relative bearing ratio and expansion characteristics under known surcharge weight of base, subbase and sub grade soils for the design of roads, pavements and runways. The CBR test is used extensively in selection of materials and control of sub grades.
