Abstract
AbstractThe coefficient of linear extensibility (COLE) measures soil swelling of natural soil clods and was designed for use in soil genesis and characterization studies. In an attempt to quantify engineering ratings of shrink‐swell potential and to enhance nonagricultural use of soil survey data COLE has been statistically related to arbitrary PVC values. However, the data used to calculate COLE can also be used to directly calculate standard engineering parameters: shrinkage limit (SL), shrinkage ratio (SR), and percentage of volumetric change (VC). These values are more widely understood by the potential user as well. COLE is being measured in standard characterization studies by the National Soil Survey Laboratory and forms an immediate data base for quantification of shrinkage factors for soil survey interpretation. SL, SR, and VC can also be calculated from some pedon characterization data measured before the COLE techniques were put into use.
