SOILS TESTING

Testing of earth materials encountered during HGEI’s field investigations is routinely conducted for the determination of soil conditions and characteristics relative to the geotechnical engineering analysis used in foundation design and recommendations with American Standard Test Methods (ASTM), including:

ASTM D122 – Particle Size Analysis

ASTM D1140 – Amount of Material Finer Than 200 Sieve (Hydrometer)

ASTM D1556 – In-Place Density Test (Sand Cone Method)

ASTM D1557 – Laboratory Compaction (Maximum Density)

ASTM D2435 – One-Dimensional Consolidation

ASTM 2487 – Unified Soils Classification System (USCS)

ASTM 3080 – Direct Shear

ASTM D4318 – Liquid Limit, Plastic Limit, and Plasticity Index (Atterberg Limits)

ASTM D4829 – Expansion Index

ASTM D6938 – In-Place Density Test (Nuclear Method)
