Subgrade Stabilization: Pavement Optimization for Asphalt and Concrete Pavements
Presented by Mr. Eden W. Thomas, P.E., with Tensar International Corporation
BIO: Mr. Eden Thomas holds a B.Sc. from Mississippi State University and a B.A. from Queen's University. He started his career as a co-op student with the United States Army Corps of Engineers where he worked on numerous flood control projects along the Mississippi River and tributary area. From 2012-2019 Eden worked in geotechnical consulting along the Gulf Coast. He has experience on a wide range of projects in the municipal, federal government, commercial, and heavy industrial sectors. In recent years he has worked extensively with design incorporating geosynthetics. Eden joined Tensar in 2019 as Area Engineer for the Gulf Coast region. He is a licensed Professional Engineer in Texas and Louisiana.
ABSTRACT: Geosynthetics have been integral to civil engineering for over 40 years, offering versatile solutions across various applications. Among these, geogrids have proven particularly effective in stabilization projects, such as subgrade stabilization for soft soils, base stabilization for pavement sections, and the stabilization of bearing pads and slopes. This presentation aims to provide a comprehensive overview of geogrid stabilization, with a specific focus on its role in geotechnical engineering and pavement design. Key learning objectives include reviewing the primary features of geogrid materials and the mechanisms that contribute to subgrade and base stabilization, defining the most common applications for geogrids, exploring real-world examples and case studies related to subgrade stabilization and pavement design, and offering practical design and specification tips.
