本欧洲标准定义了道路和机场路面不同的横向不均匀度指标和适当的评估和报告方法。 这些指标主要与测量设备无关。 本欧洲标准着重于以下三个目的的横向不均匀度测量: - 提供新铺设路面路面质量控制手段的指标，特别是对于交叉点，以及由于不正确的铺设和/或压实行为引起的不规则性的证据。 - 作为常规状态监测程序的一部分，用于评估作业中路面状况的指标。它们旨在检测由交通，路面磨损或地下运动引起的横向变形。 - 用于在使用路面上重铺活动的指数。 参数和评估方法适用于道路和机场

This European Standard defines the different transverse unevenness indices of the pavement surface of roads and airfields and the appropriate methods of evaluation and reporting. The indices have been defined principally independent of the measurement device. This European Standard focuses on transverse unevenness measurements for the following three purposes: - indices to provide a means for quality control of pavement surfaces of newly laid pavements, especially with respect to crossfall and the evidence of irregularities due to improper laying and/or compacting action. - indices to be used for evaluating the condition of pavements in service as part of routine condition monitoring programs. They are intended to detect transverse deformations caused by the traffic, pavement wear or subsurface movement. - indices to be used for resurfacing activities on pavements in use. The parameters and evaluation methods are applicable both for roads and airfields.
