9 am to 4 pm MST


Meet The Instructors

Charlie Greer spent 41+ Years with Law Engineering and its successors (MACTEC and AMEC E&I). Before his retirement in 2015, he was the Senior Vice President – Director of Engineering – Director of Quality Assurance. Charlie Greer is currently an adjunct lecturer at University of Illinois Urbana-Champaign and has been teaching Case Histories in Infrastructure Engineering for the CEE Department since 2016. He is a Professional Engineer in GA and FL.

About the Training:

Geotechnical Testing and Pavement Engineering training workshop was delivered on December 7-9, 2022. The workshop was presented by Charlie Greer. The training covered basic geotechnical testing methods and applications through case studies.

Day 1: December 7, 2022

  • General issues (contract specifications, ambiguities, and communications)
  • Basic soil and aggregate tests for pavements
    • Moisture content, gradation, Atterberg limits, moisture density (standard and modified Proctor)
  • Lab and field strength tests for soil and aggregate
    • Soil boring and standard penetration, compression (unconfined, and onfined), CBR (lab and field), LBR, R-Value, plate load test (k-value), Texas triaxial test, resilient modulus, consolidation, direct shear and vane shear test
  • Strength tests for pavement and subgrade
    • Field density (sand cone, drive tube, nuclear), pressuremeter, cone penetrometer (dynamic and static hand-held), Benkelman beam, FWD, lightweight deflectometer (LWD), rolling deflectometer, seismic analysis and surface waves (SASW), ground penetrating radar (GPR), and test pits

Day 2: December 8, 2022

  • Quality control, quality assurance, and acceptance
  • Compaction and compaction control
  • CASE HISTORY 1: Compacted subgrade too high
  • Solutions to weak soil conditions
    • Proof rolling, undercut, backfill, stabilization
  • Strength tests for concrete
    • Compressive strength, modulus and Poisson’s ratio, flexural strength, ring tensile and split tensile strength
  • CASE HISTORY 2: Concrete pavement strength penalties

Day 3: December 9, 2022

  • CASE HISTORY 3: Embankment settlement
