This specification covers the requirements for reusable and nonreusable geosynthetic alternate daily covers (ADCs) used on the working face of municipal solid waste landfills (MSWLF). Geosynthetic ADCs include a wide range of products including, but not limited to, reinforced film, unreinforced film, reinforced sheet, unreinforced sheet, coated geotextile and uncoated geotextile. Geosynthetic ADC are classified as nonreusable geosynthetic ADC, and reusable geosynthetic ADC. The breaking factor, tear resistance, and puncture strength of the nonreusable ADC shall be tested to meet the requirements prescribed. The grab strength, trapezoidal tear, and puncture resistance of the reusable ADC shall be tested to meet the requirements prescribed.

1.1 This specification covers the requirements for reusable and nonreusable geosynthetic alternate daily covers (ADCs) used on the working face of municipal solid waste landfills (MSWLFs). Geosynthetic ADCs include a wide range of products including, but not limited to: reinforced film, unreinforced film, reinforced sheet, unreinforced sheet, coated geotextile, and uncoated geotextile.

1.2 This standard addresses the base ADC materials and does not address grommets, straps, or other fabricated parts.

1.3 The values stated in SI units are to be regarded as the standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
