Soil Classification

The Soil Classification tab is used to edit the default soil classification systems used in RSLog. This mainly affects the strata description on test hole data entry page, when the Detailed View is selected by user.

Any changes in soil classification will affect the boring logs for previous and future projects.

These Soil Classification definitions are sorted into the following categories (see reference for complete details):

  • Color Terms: User can use the Munsell Soil Color charts to describe the color of a soil sample at the time of sampling. Describe the predominant colors or range of colors if there is substantial color variation using the terms in this table. For additional information, see Standard Practice for Specifying Color by the Munsell System (ASTM D1535).
  • Proportion of Soil: Report the percentage or proportion of gravel, sand, and fines, by weight of the total sample (excluding the cobbles and boulders), either by using a proportional descriptor or as a weight percentage (not a range), estimated to the nearest 5%, of the total sample excluding the cobbles and boulders (after ASTM 2488).
  • Particle Size: Describe the size of particles (after ASTM 2488).
  • Particle Angularity: Describe the angularity of the sand (coarse grains only), gravel, cobbles, and boulders (after ASTM D2488).
  • Particle Shape: Describe the shape of the gravel, cobbles, and boulders if they meet any of the criteria (after ASTM D2488).
  • Plasticity: Describe plasticity of fine-grained soil (after ASTM D2488).
  • Dry Strength: Describe dry strength of fine-grained soil (after ASTM D2488).
  • Dilatancy: Describe dilatancy of fine-grained soil (after ASTM D2488).
  • Toughness: Describe toughness of fine-grained soil (after ASTM D2488).
  • Structure: Describe structure of intact soil (after ASTM D2488).
  • Cementation: Describe the cementation of intact coarse-grained soil (after ASTM D2488).
  • Interbed Joiners: Used for describing the layer description of an interbedded/isolated later (see reference for complete details).
