The 18-page document is intended to assist pavement design engineers in five areas:

  1. What are SEGs and what functions do they serve.
  2. How to determine if geotextile materials are needed for a project.
  3. How to determine the material’s engineering properties.
  4. How to install and how to construct new pavement using geotextiles.
  5. Calculating cost savings, in the amount ofaggregate, by using geotextiles
