1.1 This specification covers the minimum material requirements and describes the procedures for installing concrete pavements and linings in corrugated steel pipes and structural plate structures in the field. Specific designs with additional or greater requirements shall be detailed in the contract documents. This specification is applicable to paving or lining new pipes and for rehabilitating existing structures. The pipe to be paved or lined is described in Specifications A760/A760M , A761/A761M , and A762/A762M . 1.2 This specification covers pipes 48 in. [1200 mm] and larger for pavements and 24 in. [600 mm] and larger for full linings. 1.3 New pipes are to be designed in accordance with Practice A796/A796M and installed in accordance with Practice A798/A798M for factory-made pipes and Practice A807/A807M for structural plate structures. Structures to be rehabilitated shall be structurally stable. 1.4 Pipes with plant installed concrete pavements and linings are covered under Specification A849 . 1.5 This specification is applicable to product in either inch/pound units as A979 or in SI units as A979M . Inch/pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text for clarity, but they are the applicable values when materials are ordered to A979M . 1.6 This standard may involve hazardous materials, operations and equipment. The 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. 1.7 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.
