MATERIAL SPECIFICATION <br />EO <br />GREW <br />The composite turf reinforcement mat (C- TRlvi) shall be a machine- produced mat of 100% coconut fiber matrix <br />incorporated into a permanent three - dimensional turf reinforcement matting. <br />The matrix shall be evenly distributed across the entire width of the matting and stitch bonded between a super heavy <br />duty UV stabilized bottom net with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, an ultra -heavy duty LTV stabilized, <br />dramatically corrugated (crimped) intermediate netting with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings, and covered <br />by a super heavy duty UV stabilized top net with 0.50 x 0.50 inch (1.27 x 1.27 cm) openings. The corrugated netting <br />shall form prominent closely spaced ridges across the entire width of the mat. The three nettings shall be stitched <br />together on 1.50 inch (3.81 cm) centers with UV stabilized polypropylene thread to form a permanent three - <br />dimensional turf reinforcement matting. <br />The 050 shall meet requirements established by the Erosion Control Technology Council (ECTC) Specification and <br />the U.S. Department bf Transportation, Federal Highway Administration's (FHWA) Standard Specifications For <br />Construction of Roads and Bridges on Federal Highway Projects, FP -03 2003 Section 713.18 as a Type SA, B, and C <br />Permanent Turf Reinforcement Mat. <br />Installation staple patterns shall be clearly marked on the turf reinforcement matting with envirorunentally safe paint. <br />All mats shall be manufactured with a colored thread stitched along both outer edges (approximately 2 -5 inches [5 -12.5 <br />cm] from the edge) as an overlap guide for adjacent mats. <br />• The composite turf reinforcement mat shall be the North American Green C350, or equivalent.
