The composite turf reinforcement tnai (C-TRM) shall be amachine-produced mat of 100% UV stabilized polypropylene fiber maVix
incorporated into a pemtanentthree-dimensional turf reinforcement matting.
The matrix shall be evenly distributed across the enttre width of the matting and stitch bonded between the bottom and middle ultra heavy
duty UV stabilized Wettings with 0.50 x 0,50 inch (117 x I.27 cm) openings and then covered by art ultra heavy duty UV stabilized
Wettings with 0.50 x 0.50 inch (]27 x 117 txrr) openings. The middle, dramatically comrgated (crimped) Hefting shall form prominent
closely spaced ridges across the entire width of the mat The three nets shall be stitched together on 1.50 inch (3.81 cm) centers with W
stabilized polypropylene thread to forth a prnnanent three-0imensional turf reinforcement matting.

BBench Scale Performance Testing
Bench scale tests are index property tests. These tests arc not indicative of field perforntance and therefore should not be used in
design to establish performance levels for rolled erosion control products. Bench scale tests are performed according to methods
developed by the Erosion Control Technology Council (ECTC).
