1.1 本规范涵盖由闭孔聚烯烃材料制成的预制伸缩缝填料，该材料具有适当的压缩性和非挤出特性。 1.1.1 I型，闭孔聚乙烯或混合聚乙烯。 1.2 这些接缝填料拟用于全深度接缝的混凝土路面。尺寸有几种不同。典型尺寸为0.5英寸。厚度（12.7 mm），4.0 在里面宽度为101.6 mm，长度为10 ft（3.048 m），将缓解应力或避免相邻结构或路面中的潜在损坏。 1.3 以英寸-磅为单位的数值应视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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, 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.
