1.1 本试验方法包括使用至少23英尺（7米）长的铰接式多轮轮廓仪测量路面粗糙度( 图1 是典型的）。 图1 典型剖面图 1.2 该试验方法利用了通过在路面上以小于3英里/小时（5公里/小时）的速度纵向移动轮廓仪而形成的表面记录。对记录进行分析，以确定粗糙率并识别超过指定阈值的凸起。 1.3 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。 1.4 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。 请参阅第节 6. 具体的危险说明。 1.5 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====== 4.1 该试验方法提供了一种测量新路面或修复路面粗糙度的方法。不同设计的轮廓仪之间的结果可能不同，因此不一定与其他轮廓仪或其他粗糙度测量设备的粗糙度测量结果一致。

1.1 This test method covers the measurement of pavement roughness using an articulated multi-wheeled profilograph at least 23 ft (7 m) long ( Fig. 1 is typical). FIG. 1 Typical Profilograph 1.2 This test method utilizes a surface record made by moving the profilograph longitudinally over the pavement at less than 3 mph (5 km/hr). The record is analyzed to determine the rate of roughness and to identify bumps that exceed a specified threshold. 1.3 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. 1.4 This standard does not purport to address all of the safety problems, 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. See Section 6 for specific hazard statement. 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. ====== Significance And Use ====== 4.1 This test method provides a means for measuring the roughness of new or rehabilitated pavements. Results may differ between profilographs of different designs and therefore will not necessarily agree with roughness measurements by other profilographs or other roughness-measuring equipment.
