1.1 本试验方法描述了使用以步行速度行驶的滚动测斜仪测量铺砌道路、桥梁和机场表面的横向和纵向表面轮廓。 1.2 其设计目的是( 1. )量化新路面和桥面的粗糙度；( 2. )研究各种施工方法对表面粗糙度的影响；( 3. )确定校正磨削的位置；和( 4. )评估校正研磨的效果。 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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。 ====意义和用途====== 5.1 本试验方法建立了收集行驶表面上纵向和横向剖面的高程和距离数据的程序。 5.2 本试验结果主要用于: 5.2.1 使用中所示的任何一种粗糙度指数来评估行驶表面的粗糙度 表1 . 各种指数计算所需的方程式包含在中所示的参考文献中 表1 . 注1: 当该测试用于评估新路面是否符合合同粗糙度规范时，与路面安装日期相关的测试的及时性至关重要。由于大多数波特兰水泥混凝土表面在安装后几天内会因温度和湿度梯度的变化而改变形状，这会导致接缝、裂缝和板边缘出现卷曲，仅用于承包商质量控制，因此可能需要在路面安装后72小时内收集剖面数据。 5.2.2 调查不同施工方法对产生的路面表面粗糙度的影响。 5.2.3 调查( 1. )由于卷曲而导致的路面，以及( 2. )桥梁和其他结构内结构构件的挠度。 5.2.4 确定需要纠正磨削的位置。 5.2.5 根据试验方法，使用计算机模拟测量车辙深度 E1703/E1703M .

1.1 This test method describes the measurement of transverse and longitudinal surface profiles on paved road, bridge, and airport surfaces using a rolling inclinometer traveling at walking speed. 1.2 It is designed to ( 1 ) quantify the roughness of new pavements and bridge decks; ( 2 ) investigate the effect of various construction methods on surface roughness; ( 3 ) determine the location for corrective grinding; and ( 4 ) evaluate the effect of corrective grinding. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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. ====== Significance And Use ====== 5.1 This test method establishes procedures for collecting elevation and distance data of longitudinal and transverse profiles on a traveled surface. 5.2 Results of this test are used primarily to: 5.2.1 Evaluate the roughness of traveled surfaces, using any of several roughness indices shown in Table 1 . Equations required for calculations of various indexes are contained in references shown in Table 1 . Note 1: When this test is used to evaluate the compliance of a new pavement surface with contract roughness specifications, the timeliness of the test in relation to the date of the surface's installation is of critical importance. Since most portland cement concrete surfaces will change shape within a few days after installation—due to changes in thermal and moisture gradients which cause curling at joints and cracks and slab edges—for contractor quality control only, it may be desirable to gather profile data within 72 h after pavement installation. 5.2.2 Investigate the effect of different construction methods on resulting pavement surface roughness. 5.2.3 Investigate the curvature of ( 1 ) pavement surfaces due to curling, and ( 2 ) deflection of structural members within bridges and other structures. 5.2.4 Identify the locations in need of corrective grinding. 5.2.5 Measure rut depth using computer simulation in accordance with Test Method E1703/E1703M .
