Course Synopsis:

Water content of soil is defined as the ratio, expressed as a percentage, of the weight of water in a given soil mass to the weight of the solid particles.

These tests are more commonly performed in the laboratory but may also be performed in the field. Test results are used in various engineering applications, such as the Atterberg Limits, compaction tests for maximum density and optimum moisture, and control of fill in embankments for compaction testing and optimization.  Additionally, moisture contents are determined on subsoil samples for structural engineering purposes.

It is imperative that the specified, published test method be strictly followed.  Otherwise, the results may be deemed invalid, resulting in inaccurate results, potentially inaccurate soils engineering, and significant cost to the company or agency performing the tests.  There is essentially no room for mistaken test methods or procedures.  Shortcuts are not acceptable.

Course Objectives:

This course teaches the following specific knowledge and skills regarding Water Content determinations:

  • Definitions

  • Apparatus for performing the tests

  • Test procedures

  • Computations

  • Possible errors

  • Charting and Reporting
