C. Acceptable reinforced GCL products are Bentomat® DN, as manufactured by <br />CETCO, 1350 West Shure Drive, Arlington Heights, Illinois 60004 (847-392-5800), <br />or an engineer-approved equal. <br />D. The reinforced GCL and its components shall have the properties shown in <br />Table 2.01-1. <br />TABLE 2.01-1- GCL PROPERTIES <br />• <br /> <br />Material Property <br />Test Method Test Frequency <br />(ft) <br /> <br />Required Values <br />Bentonite Swell Index' ASTM D 5890 1 per 50 tons 24 mL/2 min. <br />Bentonite Fluid Loss' ASTM D 5891 1 per 50 tons 18 mL max. <br />Bentonite Mass/Area2 ASTM D 5993 40,000 ft2 0.75 lb/ft2 min <br />GCL Grab Strength 3 ASTM D 6768 200,000 ft2 50 lbs/in MARV <br />GCL Peel Strength 3 ASTM D 6496 40,000 ft2 3.5 lb/in min <br />GCL Index Flux4 ASTM D 5887 Weekly 1 x 10-8 m3/m2/sec max <br />GCL Hydraulic Conductivity 4 ASTM D 5887 Weekly 5 x 10-9 cm/sec max <br />GCL Hydrated 5Internal <br />Shear Strength ASTM D 5321 <br />ASTM D 6243 Periodic 500 psf typical <br />Notes <br />Bentonitc property tests performed at a bentonite processing facility before shipment to CETCO's GCL production facilities. <br />2 Bentonitc mass/area reported at 0 percent moisture content. <br />3 All tensile strength testing is performed in the machine direction using ASTM D 6768. Upon request, tensile results can be <br />reported per modified ASTM D 4632 using 4 inch grips. <br />4 Index flux and permeability testing with dcaired distilled/deionized water at 80 psi (551 kPa) cell pressure, 77 psi (531 kPa) <br />headwater pressure and 75 psi (517 kPa) tailwater pressure. Reported value is equivalent to 925 gal/acre/day. This flux value is equivalent <br />to a permeability of 5x 10-9 cm/sec for typical GCL thickness. Actual flux values vary with field condition pressures. The last 20 weekly <br />values prior the end of the production date of the supplied GCL may be provided. <br />5 Peak value measured at 200 psf (10 kPa) normal stress for a specimen hydrated for 48 hours. Site-specific materials, GCL <br />products, and test conditions must be used to verify internal and interface strength of the proposed design. <br />2.02 PRODUCT QUALITY DOCUMENTATION <br />A. The GCL manufacturer shall provide the Owner or other designated party with <br />manufacturing QA/QC certifications for each shipment of GCL. The certifications <br />shall be signed by a responsible party employed by the GCL manufacturer and shall <br />include: <br />1. Certificates of analysis for the bentonite clay used in GCL production <br />demonstrating compliance with the parameters swell index and fluid loss <br />shown in Table 2.01-1. <br />2. Manufacturer's test data for finished GCL product(s) of bentonite mass/area, <br />GCL tensile strength and GCL peel strength (reinforced only) demonstrating <br />compliance with the index parameters shown in Table 2.01-1. <br />3. GCL lot and roll numbers supplied for the project (with corresponding shipping <br />information). <br />• B. Prior to shipment, the GCL manufacturer shall label each roll, identifying: <br />Revision A <br />02271-3 <br />January 2008 <br />.
