Montana DOT has one of the more complicated DOT specifications for geotextiles. It is based on AASHTO M 288 with several modifications for AOS and permittivity. The manner in which it is published is also a little difficult. Below are US Fabric's geotextile products that meet the Montana DOT geotextile specification, listed by their application. US Fabrics products are not listed on the Montana DOT Qualified Products list and the table below is offered as a guideline only.
