Massachusetts DOT produced a Supplemental Geotextile Specification to the old 1995 Standard Specification in 2006. It states:
"SUBSECTION M9.50.0 Geotextile Fabrics. (page III.98) Replace existing Subsection with the following: Geotextile fabric used for subsurface drainage, separation, stabilization, permanent erosion control, temporary silt fences, or paving fabric shall conform to requirements of AASHTO M 288 for the intended application."
However, the Massachusetts DOT Qualified Construction Materials List is very broad and does not appear to have any connection to AASHTO M288. Below are US Fabrics' geotextile products meeting AASHTO M288, listed by their application (Click on the red product name for a data sheet):
