Geotechnical soil method selection
Particle-size distribution (D6913 sieve, D7928 hydrometer), Atterberg plasticity limits (D4318), compaction (D698) and hydraulic conductivity (D5084) characterize engineering behaviour.
Sample considerations
- ASTM D6913/D6913M: Soil type, gradation range, specimen mass and dispersion approach
- ASTM D7928: Fine fraction, dispersant, specific-gravity basis and reporting format
- ASTM D4318: Fine fraction preparation, liquid/plastic limit objective and classification context
- ASTM D698: Soil, moisture range, mould size and maximum-density/optimum-moisture objective
- ASTM D5084: Specimen preparation, confining pressure, saturation method and gradient
