IFAI Webinar: Flexible Pavement Design with Geogrids – Design Theory, Technical Basis, and State of the Practice – Part 1
May 28 @ 10:00 am - 11:00 am
This two-part webinar will discuss the use of geogrids in flexible pavements, with a focus on the requirements for proper design and successful applications.
As pavement design methods have advanced over the past 75 years, the materials and construction techniques used have also advanced. While geosynthetics were first used to improve road performance as far back as the 1930s, the incorporation of these materials into standard flexible pavement design, specifically AASHTO methods, is a much more recent phenomenon. In particular, over the past 25 years, extensive testing on geogrids has provided the data and understanding necessary to precisely quantify their contribution to pavement performance and perform enhanced designs.
These sessions will provide a detailed overview of the design of flexible pavements using geogrids, including the underlying pavement design methods, the requirements for quantifying benefit and validating performance, and the proper means of incorporating the contribution of geogrids within accepted design methodology.
