Topic:  Back to Basics with Geogrids

Presentation: Online video

Summary: We’re going back to basics, but adding in new developments. For decades geogrids have been successfully utilized for subgrade stabilization and pavement optimization applications. During that time, the industry’s knowledge base has grown substantially. Recently, several new tools, methods, and products have been introduced that will enhance design capabilities

In this session, we will:

  • Introduce geogrids used for soil stabilization applications and their performance mechanisms and benefits for construction

  • Discuss fundamental concepts of Subgrade Stabilization using geogrids, other geosynthetics, and conventional methods

  • Give guidance for design and a discussion of performance and specification criteria

  • Provide a brief introduction to the concepts of Pavement Optimization using geogrid. We review the fundamentals of AASHTO flexible pavement design, show how geogrid can be properly integrated into the design, and discuss best practices for ensuring reliability in pavement performance.

  • Discuss relevant case studies of these applications.

Steve is a 1995 graduate of Mississippi State University with a B.S. in civil engineering and has been a professional engineer since 2000. He has been working in the geosynthetics industry for over 10 years and loves the unique challenges that working for Tensar routinely brings. Prior to his current position with Tensar, Steve worked as the market manager for marine and ports which exposed him to a multitude of exciting projects worldwide. He currently lives in Wilmington, NC and manages the sales and marketing efforts of Tensar’s roadway applications in South Carolina, North Carolina, Virginia, and Washington, DC.
