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.
