1.1 本规程涵盖了沥青洒布机横向和纵向施用率以及剩余施用率的测定，单位为加仑/平方码（或升/平方米）。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 3.1 选项A- 使用沥青洒布机施涂到路面上的沥青材料的横向和纵向施涂率以及施涂率的可变性可以使用选项a进行估计。 3.2 选项B- 使用沥青洒布机将乳化沥青应用于路面的横向和纵向残余应用率以及残余应用率的可变性可以通过使用选项B进行估计。

1.1 This practice covers the determination of transverse and longitudinal application rate and residual application rate of asphalt distributors in gallons per square yard (or litres per square metre). 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 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 ====== 3.1 Option A— The transverse and longitudinal application rate and variability in application rate of bituminous material applied to a pavement surface using a bituminous distributor can be estimated using Option A. 3.2 Option B— The transverse and longitudinal residual application rate and variability in residual application rate from emulsified asphalt applications to a pavement surface using a bituminous distributor can be estimated by using Option B.
