Goals and Progress for Nonwoven Geotextile Interlayers

An Expert Task Group (ETG) has been assembled and has identified three goals regarding Nonwoven Geotextile Interlayers in Concrete Pavements:

  1. Develop guidance and specifications for the use of nonwoven geotextile interlayers on concrete pavement and concrete overlay projects.
  2. Create and maintain a common database that identifies projects past, ongoing, and planned.
  3. Facilitate technology transfer, including identification of the best mechanisms.

On May 1st, 2010, a Test Methods Working Group (TMWG) consisting of representatives from materials manufacturers, state ACPAs, DOTs, contractors and the CP Tech Center met with the goal in mind of developing test methods.
