SAND CONE DENSITY TEST (ASTM D 1556)

The Sand Cone Density Test is conducted to determine the in-place density and unit weight of soils. This test is suitable for soils with minimal rock or coarse aggregates larger than 1.5 inches. It provides accurate measurements for intact or in situ soils with small natural voids, sufficient cohesion, and stability during excavation. This method is essential for construction and engineering projects that require precise soil density assessments such as foundations and pavements.

CORE CUTTER TEST (ASTM D 1556)

The Core Cutter Density Test assesses the in-situ density and compaction of soil. By extracting a cylindrical soil core, dimensions and weight are measured to calculate the dry density. This test is essential for evaluating soil compaction in construction projects like highways and embankments, ensuring the quality and stability of soil layers in geotechnical engineering applications.
