SUPPLEMENTAL SPECIFICATION <br />AM~I~C N P300 <br />GREEtV' <br />The North American Green P300 permanent turf reinforcement mat shall be constructed of 100% UV stabilized <br />565 denier polypropylene fiber sewn between a black UV stabilized 0.50 x 0.50 inch (1.27 x 1.27 cm) mesh <br />polypropylene netting on the top (5 Ibs/1,000 fry) and a black UV stabilized 0.625 x 0.625 inch (].59 x 1.59 cm) <br />mesh polypropylene netting on the bottom (3 lbs/],000 fr'). The P300 is sewn together using UV stable <br />polypropylene thread stitched on 1.50 inch (3.81 cm) centers. The mat is highly resistant to ultraviolet and <br />biological degradation. The following list contains further physical properties of the P300 erosion control/turf <br />reinforcement mat. <br />Pro a Test Method <br />Thickness ASTM D6S25 <br />Resiliency ASTM DI777 <br />Density ASTM D792 <br />Mass per Unit Area ASTM D6566 <br />Porosity ECTC Guidelines <br />Open Volume per Unit Area ECTC Guidelines <br />Stiffness ASTM D1388BCTC <br />Light Penetration ECTC Guidelines <br />UV Stability ASTM D4355** <br />MD Tensile Strength ASTM D6818 [D503S] <br />MD Elongation ASTM D6818 [D5035] <br />TD Tensile Strength ASTM D6818 [D5035] <br />TD Elongation ASTM D6818 [DS03S] <br />ical <br />O.S4 in (13.72 mm) <br />91.50% <br />0.513 oz/ina (0.890 g/cm3) <br />11.46 oz/yd2 (389 g/mz) <br />95.89% <br />872 in3/yd2 (11,952 cm3/mZ) <br />97.24 oz-in (1,085,378 mg-cm} <br />15% <br />90 <br />481 Ibs/ft (7.02 kN/m) [379 lbs/ft (5.53 kN/m)] <br />20 % [26 %] <br />4261bs/ft (6.22 kN/m} [403 lbs/ft (5.88 kN/m)j <br />23 % [27 %] <br />'•ASTM DI682 (4 inch strip) Tensile Strength and %Sttength Retention ofmaterial fallowing 1000 hts exposure in Xenon-Arc Weadrerometer. <br />MD-Machine direction <br />TD -Transverse direction <br />Bench Scale Testinet <br />Test Method - Descri tion Parameters Results <br />ECTC Method 2 -Determination of 50 mm (2 in)/Iv for 30 min Soil loss ratio* = 11,92 <br />' <br />unvegetated RECP <br />s ability to protect 100 mm (4 in)/hr for 30 min Soil loss ratio* = 10.79 <br />soil from rain splash and associated <br />runoff 150 mm (6 in)/hr for 30 min Soil loss ratio* = 10.17 <br />ECTC Method 3 -Determination of Shear: 2.73 Ibs/ft' for 30 min Soil loss: 383g <br />' <br />unvegetated RECP <br />s abiliTy to protect Shear: 3.40 Ibs/ftr for 30 min Soil loss: 451g <br />soil from hydraulically-induced shear <br />stress.
