1.1 本规程涵盖了符合规范要求的乳化精制煤焦油浆的应用 D6945/D6945米 I型和II型，由机械化设备制成，用作沥青混凝土路面上的防风雨和耐石油（脂族）溶剂密封剂。为了澄清I型和II型之间的差异，请参见 3.3 用于术语的标准定义。 1.2 以国际单位制或英寸磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本规程旨在为建筑师、工程师、业主或其代表或其组合提供指南。它的使用有助于确保在沥青混凝土路面上使用保护涂层系统时，其性能令人满意。

1.1 This practice covers the application of emulsified refined coal tar slurry meeting the requirements of Specification D6945/D6945M Types I and II, by mechanized equipment as a weather protection and petroleum (aliphatic) solvent resistant sealer for use on bituminous concrete pavements. In order to clarify the differences between Types I and II, see 3.3 for standard definition of terms. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 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. 1.4 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. ====== Significance And Use ====== 4.1 This practice is designed as a guide for architects, engineers, property owners or their representatives, or combination thereof. Its use helps ensure the satisfactory performance of the protective coating system when applied over bituminous concrete pavements.
