Forward Landfill WMU FU-23 <br />02778 2 HDPE GEOMEMBRANE <br />Test. 8. D5596, Test Method for Microscopic Evaluation of the Dispersion of Carbon Black in Polyde Geosynthetics. 9. D5994, Test Method for Measuring the Core Thickness of Textured Geomembranes. 10. D6392, Standard Practice for Determining the Integrity of Nonreinforced Geomembrane Seams Produced Using Thermo-Fusion Methods. 11. D6693, Standard Test Method for Determining Tensile Properties of Nonreinforced Polyethylene and Nonreinforced Flexible Polypropylene Geomembranes. 1.3 DEFINITIONS <br />A. Batch: A quantity of resin, usually the capacity of one railcar, used in the fabrication of high-density polyethylene (HDPE) geomembrane sheet. The finished sheet will be identified by a roll number corresponding to the quantity of resin used. <br />B. Bridging: The condition when geomembrane becomes suspended over its subgrade due to contraction of the material or poor installation. <br />C. QA/QC Consultant: The party, independent from Manufacturer or CONTRACTOR, that is responsible for observing and documenting activities related to the quality assurance of production and installation of the geosynthetic components of the lining system. <br />D. Construction Quality Assurance (CQA) Laboratory: The party, independent from the OWNER, Manufacturer, Fabricator, and Installer, responsible for conducting tests on samples of geosynthetics obtained at the site. <br />E. Extrudate: The molten polymer that is emitted from an extruder during seaming using either extrusion fillet or extrusion flat methods. The polymer is initially in the form of a ribbon rod, bead or pellets. <br />F. Fabricator: The party responsible for the fabrication of geomembrane panels constructed from rolls received from the manufacturer. <br />G. Geomembrane Manufacturer: The party responsible to produce the geomembrane rolls from resin and for the quality control of the resin. <br />H. Geomembrane: An essentially impermeable membrane used as a solid or liquid barrier. Synonymous term for flexible membrane liner (FML). <br />I. Geomembrane Subsurface: The soil or geosynthetic surface on which the geomembrane lies. <br />J. GEOSYNTHETICS CONTRACTOR: The party responsible for field handling, transporting, storing, deploying, seaming, temporarily restraining (against wind), and installing the geomembrane.
