Core Material Testing Services LLP

Soil Testing Services are essential for evaluating soil properties, ensuring foundation stability, and optimizing construction, agriculture, and geotechnical projects. These tests help determine soil strength, composition, moisture content, and load-bearing capacity following standards like IS 2720, ASTM D2487, BS 1377, and AASHTO T88.

✅ Moisture Content Test (IS 2720-Part 2, ASTM D2216) – Determines water content for soil classification

✔ Ensures soil suitability for road, building, and bridge projects
✔ Reduces risks and improves cost efficiency in design
✔ Complies with industry safety and geotechnical standards

Subgrade Soil Testing Service evaluates the strength, stability, and suitability of the soil beneath roads, highways, and pavements. This ensures that the subgrade can support traffic loads without excessive settlement or deformation. Testing is performed as per MORTH, IS 2720, ASTM D698, and AASHTO T99 standards to determine soil classification, compaction, moisture content, and bearing capacity.

✅ Sieve Analysis (IS 2720 Part 4, ASTM D6913) – Determines particle size distribution
✅ Atterberg Limits (Liquid Limit, Plastic Limit) (IS 2720 Part 5 & 6, ASTM D4318) – Defines soil plasticity and workability
✅ Specific Gravity Test (IS 2720 Part 3, ASTM D854) – Helps classify soil density and composition

✅ California Bearing Ratio (CBR) Test (IS 2720 Part 16, ASTM D1883) – Should be ≥5% for roads, ≥8% for heavy loads
✅ Unconfined Compressive Strength (UCS) Test (IS 2720 Part 10, ASTM D2166) – Determines soil's shear strength
✅ Triaxial Shear Test (IS 2720 Part 11, ASTM D2850) – Measures stability under load

✅ Moisture Content (IS 2720 Part 2, ASTM D2216) – Helps determine optimum water levels for compaction
✅ Proctor Compaction Test (OMC & MDD) (IS 2720 Part 8, ASTM D698, AASHTO T99) – Ensures proper soil compaction levels
✅ Field Density Test (Sand Replacement/Core Cutter Method) (IS 2720 Part 28, ASTM D1556) – Verifies compaction at site

✅ Permeability Test (IS 2720 Part 17, ASTM D5084) – Determines water flow and drainage capability
✅ Swelling Pressure Test (IS 2720 Part 41, ASTM D4546) – Checks expansive soil behavior
