1.1 本规范涵盖了混凝土路面预制氯丁橡胶接缝密封的材料要求。密封件由多个腹板设计组成，仅通过压缩接头表面之间的密封件发挥作用，密封件在顶部向内折叠以便于压缩。密封件装有润滑剂，设计用于密封接头并拒绝不可压缩物。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准无意解决与其使用相关的安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 注1: 本规范仅为制造和采购规范，不包括尺寸选择或接缝密封安装的要求或考虑因素。然而，经验表明，该产品的成功性能取决于尺寸和交叉的正确选择- 路面将暴露在的环境条件下的接缝密封的截面设计、接缝尺寸和接缝间距，以及接缝密封的安装注意事项。

1.1 This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for concrete pavements. The seal consists of a multiple web design and functions only by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seal is installed with a lubricant and is designed to seal the joint and reject incompressibles. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address 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. Note 1: This specification is a manufacturing and purchasing specification only and does not include requirements or considerations for selection of size, or the installation of the joint seals. However, experience has shown that successful performance of this product depends upon the proper selection of size and cross-sectional design of the joint seal, joint size, and joint spacing for the ambient conditions the pavement will be exposed to, and care in the installation of the joint seals.
