Geotextiles & DOT Specifications

JAN 2019

ODOT

The Oregon DOT has developed its own geotextile specifications. They appear to be informed by AASHTO M288. 

We do not recommend a woven slit-film such as US 315 for Embankment applications even though it meets the specification.

Oregon DOT does not have a QPL for geotextiles. Strata geogrids are listed on the QPL for geogrids.

Below are US Fabric's geotextile and geogrid products that meet the Oregon DOT specifications, listed by their application.

NOTES:

• The above information is to be used only as a guide.

• Products on the above list can change without notice.

1) US 315 meets the specification, but we believe this application is not suited for a woven slit-film product.
