Quality Test of Soil

  • Grain Size Analysis - quantitative determination of the distribution of particle sizes in soils
  • Liquid Limit and Plastic Limit - determination of the liquid limit, plastic limit, and the plasticity index of soils
  • Unified Soil Classification System - a system for classifying mineral and organo-mineral soils for engineering purposes based on laboratory determination of particle-size characteristics, liquid limit, and plasticity index and shall be used when precise classification is required
  • Specific Gravity - determination of the specific gravity of soil solids that pass the 4.75-mm (No. 4) sieve, by means of a water pycnometer
  • Dry Density/Moisture Content Relation of Soil (Standard) - laboratory
    compaction methods used to determine the relationship between molding water content and dry unit weight of soils compacted in a mold using a compactive effort of 600 kN-m/m^3
  • Dry Density/Moisture Content Relation of Soil (Modified) - laboratory compaction methods used to determine the relationship between molding water content and dry unit weight of soils compacted in a mold using a compactive effort of 2700 kN-m/m^3
  • California Bearing Ratio - determination of the California Bearing Ratio (CBR) of laboratory compacted specimens
