Geotextiles & DOT Specifications

JAN 2020


US FABRICS IS NTPEP/AASHTO COMPLIANT. US Fabrics' products are not currently on the QPL.

They currently follow a REVISED 2015 version that follows AASHTO, but with a permittivity requirement of .50 on Subsurface Drainage, Separation & Stabilization. We were forwarded a copy by AKDOT. The 2017 Specification does not reflect this and we have been told a 2019 version is forthcoming that will reflect these requirements.

Below are US Fabric's geotextile products that meet current Alaska DOT geotextile specification, listed by their application.
