ASTM D 8139 : 2017

1.1This specification covers preformed expansion joint fillers made from closed-cell polypropylene foam materials having suitable compressibility, recovery from compression, nonextruding, and weather-resistant characteristics.

1.2These joint fillers are intended for use in concrete pavements in full-depth joints. There are several variations in size with typical thicknesses of ¹/₂in. (12.7 mm), ³/₄in. (19.05 mm), and 1 in. (25.4 mm); typical widths of 3¹/₂in. (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 10 ft (3.05 m).

1.3The values stated in inch-pound units are to be regarded as the standard.

1.4This 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.

1.5This 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.
