Each of these sample coupons <br />' shall be 1 inch (0.25 mm) wide by 12 inches (0.3 m) bng with the seam centered parallel to <br /> the length. The distance between these two samples shall be 42 inches. <br />' If both sample coupons pass the field test described in Section 3.3.8.5, a sample shall tre cut <br /> between the hvo coupons. This sample shall be cut into three parts and distributed as <br /> follows: <br />' One portion to the Installer (CLI) for testing, 18 inches X 12 inches; <br />' One portion for Geosynthetic Oualiry Assurance Laboratory testing if applipble, 12 inches X <br />12 inches (0.3 m X 0.3 m); and <br /> One portion to the Owner for archive storage, 12 inches X 12 inches (0.3 m X 0.3 m). <br /> i <br />' <br /> on Meeting. <br />made at the Pre-Construct <br />Final determination of the sample s¢es shall be <br />1 Destructive Testing of Seams: <br />' Destructive testing of seams is very important bequse it provides the only direct evaluation <br />of seam strength. <br />Destructive testing involves two techniques: 1) shear testing, and 2) peel testing. Shear <br />testing applies a tensile stress from the top sheet through the weld and into the bottom <br />sheet Peel testing peels the top sheet back against the overlapped edge of the bottom <br />sheet in order to observe how separation occurs. The peel test indiptes whether or not the <br />sheets are continuously and homogeneously connected through the seam <br />'1 <br /> <br />1 <br /> <br />1 <br />' 11 <br />1 <br />
