This “white paper” is provided in response to the requests from AASHTO Subcommittee on Materials Technical Section 4E Task Force on Geogrid/Geotextile Specification, to provide background information and specifications for the use of geogrids and geotextiles in pavement system applications. The white paper contains the following items.
- Summary of Installation Damage Studies
- Summary of Base Reinforcement Performance Studies
- Summary of Ongoing Work
- Proposed Applications Specifications
- Research Needs
The members of the Geosynthetics Materials Association are extremely appreciative of the opportunity to provide these proposed standard specifications to the AASHTO committee. We believe that the AASHTO committee will recognize the benefit to these specifications, and we look forward to discussing the specifications in more detail with the AASHTO committee and/or answering any questions that might arise.
