"They are rigorous, they’re about making sure our labs, personnel, and test methods conform, that they’re in compliance. They’re independent, not driven by a vendor or a construction company.”

April 2021 Online Geotechnical Training Course

April 6-8, 2021 - Online

Course Summary
This 4.5-hour virtual Geotechnical Training course is designed for laboratory personnel to enhance their understanding of one-dimensional consolidation testing of soils. This detailed course will focus on performing the test in accordance with AASHTO T 216 and ASTM D2435 test methods.

Training conducted live via Zoom Meetings.

Subject matter experts will provide a live, interactive demonstration of the consolidation test, including:

  • apparatus requirements, including equipment verification and calibration
  • sample preparation procedures
  • specimen consolidation
  • plotting and key calculations
  • geotechnical engineering concepts and consolidation theory will be discussed to aid students in their comprehension of procedures and test results

Students will receive a laboratory workbook which includes: a checklist of the apparatus requirements and procedural steps student exercises example graphs and datasheets Students will perform graphing and calculation exercises using the provided workbook and will be able to ask questions after each of the live instructor-led training lessons. Students completing the course will receive a certificate of completion and are eligible to receive 4.5 professional development hours (PDHs).

Field sampling methods and specimen preparation procedures will be covered to learn techniques for handling and trimming of specimens. The training will also cover basic geotechnical engineering concepts and theory to aid students in their overall comprehension of the procedures, results, and significance of these laboratory tests.

Scope of Training

Test Method Covered

  • AASHTO T 216/ASTM D2435: One Dimensional Consolidation

Referenced Sampling Methods

  • AASHTO T 207/ASTM D1587: Thin-Walled Tube Sampling of Soils
  • ASTM D3550: Thick Wall, Ring Lined, Split Barrel, Drive Sampling of Soil

Course Learning Objectives
Students completing this course will possess knowledge and skills necessary to operate consolidation testing equipment and understand the key steps used to perform consolidation testing in the laboratory.

Upon completion of this course, students should be able to:

  • Discuss basic engineering principles of soil compression testing and application in engineering design.
  • Explain procedures used to handle and prepare samples used for consolidation testing.
  • Understand the apparatus, procedure, and reporting requirements for consolidation testing.
  • Describe common errors associated with consolidation testing.
  • Explain calibration, standardization and checking requirements for consolidation testing.
