Soil Classification and Index Properties: A Practical Guide for Engineers (Webinar)

In Soil Classification and Index Properties: A Practical Guide for Engineers, you'll learn ...

• Standard index property tests including moisture content, unit weight, Atterberg Limits, grain size distribution, hydrometer analysis, and organic content
• Correlations between index properties and engineering behavior
• Commonly used field methods such as the shear vane test and pocket penetrometer
• Major soil classification systems, including USDA, AASHTO, USCS, and OSHA methods

Overview

---

Understanding soil behavior begins with accurate classification and laboratory testing. This webinar was developed to provide engineers with practical, working knowledge of soil classification systems and index property testing - two fundamental pillars in geotechnical design and construction.

Participants will gain insight into standard index property tests including moisture content, unit weight, Atterberg Limits, grain size distribution, hydrometer analysis, and organic content. The webinar also covers correlations between these index properties and engineering behavior, providing valuable context for field applications. In addition to lab-based testing, commonly used field methods such as the shear vane test and pocket penetrometer are reviewed to support quick, on-site soil strength evaluations.

The webinar concludes with an in-depth review of major soil classification systems, including USDA, AASHTO, USCS, and OSHA methods. Attendees will understand how to apply each system, supported by real-world examples that bridge theory and practice. Tailored for all professional engineers, this webinar also benefits builders, architects, project managers, quantity surveyors, QA professionals, academics, and students. Whether you’re starting your career or an experienced professional refreshing your knowledge, this webinar delivers the tools and insights needed to succeed.
