1.1本指南涵盖了获得一组具有广泛物理特性的代表性公路路面路段的主观数字行驶评级的程序。 1.2本指南的目的是描述一种程序，用于为行驶质量分布接近感兴趣的公路总人口的路面路段分组生成一组主观推导的比较比例行驶评级。如果可以询问整个用户群体，该集合将提供同一组路面路段的平均主观行驶评级的统计估计。 1.3为了使数据合理地表示整个公路路面的平均行驶质量判断，必须遵守某些抽样理论规则。评级小组的规模、从用户群体中选择其成员、量化个人判断的方法以及选择样本路面路段都是需要考虑的重要方面。 1.4产生的行驶质量数据的一个重要用途是确定路面样本物理参数（如测量纵断面等）的各种假设确定性函数的能力。 ，以提供主观行驶质量判断的估计。 1.5本指南基于NCHRP报告275附录F和NCHRP报告308附录E中所述的指南。 1.6以英寸-磅单位和国际单位制表示的数值应单独视为标准。括号中给出的单位仅供参考。 1.7本标准无意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和健康实践，并确定监管限制的适用性。

1.1 This guide covers a procedure for obtaining subjective numerical ride ratings for a group of representative highway pavement sections having a broad spectrum of physical characteristics. 1.2 The intent of this guide is to describe a procedure for generating a set of comparative scaled ride ratings, subjectively derived, for a subgroup of pavement sections having a ride quality distribution approximating the general population of highways of interest. This set will provide statistical estimates of the average subjective ride ratings which would be obtained for the same group of pavement sections if the entire population of users could be interrogated. 1.3 For the data to be a reasonable representation of the average ride quality judgments of the total highway pavements, certain sampling theory precepts must be observed. The size of the rating panel, the selection of its members from the user community, the method of quantifying the individual judgments as well as the selection of the sample pavement sections are all important areas to be considered. 1.4 An important use of the resulting ride quality data would be to determine the ability of various hypothesized deterministic functions of physical parameters of the pavement samples such as measured longitudinal profile, etc., to provide an estimate of subjective ride quality judgments. 1.5 This guide is based on guidelines described in Appendix F of NCHRP Report 275, and in Appendix E of NCHRP Report 308. 1.6 The values stated in both inch-pound units and SI units are to be regarded separately as the standard. The units given in parentheses are for information only. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use.
