Specification Strategies for the Use of Geosynthetics in Highway Pavements

This educational unit takes a look at two specification strategies, method specifications and performance specifications, for highway applications. It examines their basis, advantages, and their disadvantages as well as selection criteria to help you determine which specification process is most appropriate for a given project. This specification strategy comparison will benefit civil, environmental, and structural engineers who design, or write specifications for public works, roadway, or highway projects.
