Course Objectives: This course prepares construction and materials personnel with the basic skills and guidance to properly perform field testing and inspection of subgrade, embankment, and shallow foundations for various structures. This course also describes common geotechnical problems and the remedial actions generally used to correct them.
Upon successful completion of the course, students should be able to:
• Determine the field moisture content along with the in situ wet and (corresponding) dry densities
• Use the Family of Curves and One-Point Proctor to determine the Standard Dry Density (SDD) and Optimum Moisture Content (OMC) of a given soil
• Determine percent compaction and percent of OMC
• Determine soil stability and strength in the field using a Static and Dynamic Cone Penetrometer
• Properly inspect embankment construction
• Check roadway subgrades and determine undercut and treatment depths
• Perform inspection and soil testing to verify or establish the adequacy of foundation material for box culverts and shallow structure foundations
Successful completion of this course meets consultant eligibility requirements for Department prequalification only. This course does not fulfill Quality Management System certification requirements for AASHTO accreditation.
