1、Designation: D8139 17Standard Specification forSemi-Rigid, Closed-Cell Polypropylene Foam, PreformedExpansion Joint Fillers for Concrete Paving and StructuralConstruction1This standard is issued under the fixed designation D8139; the number immediately following the designation indicates the year of

2、original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers preformed expansion jointfillers

3、made from closed-cell polypropylene foam materialshaving suitable compressibility, recovery from compression,nonextruding, and weather-resistant characteristics.1.1.1 Type I, closed-cell polypropylene foam.1.2 These joint fillers are intended for use in concretepavements in full-depth joints. There

4、are several variations insize with typical thicknesses of12 in. (12.7 mm),34 in.(19.05 mm), and 1 in. (25.4 mm); typical widths of 312 in.(88.9 mm), 4 in. (101.6 mm), 5 in. (127 mm), 6 in.(152.5 mm), 7 in. (177.8 mm), 8 in. (203.2 mm), or 48 in.(1.2 m) sheet; and typical lengths of 5 ft (1.52 m) and

5、 10 ft(3.05 m).1.3 The values stated in inch-pound units are to be regardedas the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and envi
