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

1.1.1 Type I, closed-cell polyethylene or blended polyethylene.

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 and health practices and determine the applicability of regulatory limitations prior to use.
