ASTM D7174-05R22 - Standard Specification for Preformed Closed-Cell Polyolefin Expansion Joint Fillers for Concrete Paving and Structural Construction

1.1 This specification covers preformed expansion joint fillers made from closed-cell polyolefin materials having suitable compressibility and nonextruding characteristics.

1.2 These joint fillers are intended for use in concrete pavements in full-depth joints. There are several variations in size. A typical size measures 0.5 in. (12.7 mm) in thickness, 4.0 in. (101.6 mm) in width, and 10 ft (3.048 m) in length and will relieve stress or avoid potential distress in adjacent structures or pavements.

1.3 The values stated in inch-pound 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.
