Geotextiles & DOT Specifications

JAN 2020


Maryland DOT document MSMT "Geotextile Acceptance & Quality Control Assurance Procedures" requires geotextiles be tested by and listed with NTPEP. US Fabrics geotextile products are current with NTPEP. They appear to follow AASHTO M 288 as a guideline, with the exception of Class E. For puncture they reference the new ASTM D-6241 CBR method, but the values they list appear to be related to the outdated ASTM 4833 method.

Below are US Fabric's geotextile products that meet the Maryland DOT geotextile specification, listed by their application. US 160NW & US 205NW are on the List of Qualified Materials.
