Characterization of pavement texture using surface profiles — Part 7: Classification, requirements and verification of profilometers

Апстракт

Basic terms and parameters related to macro- and megatexture measurement will be described in the document, as well as a classification of profilometers with respect to their precision, bandwidth and measurement speed. Further the new standard will describe a series of performance requirements which should be met and a number of tests which should be carried out by the users of laser profilometers on a regular basis in order to verify the proper function of their apparatus. The new standard will also include an informative annex describing how an enveloped profile can be calculated, as well as annexes describing how to deal with invalid readings and how to detect and eliminate erroneous spikes in the profile. Part 6 is a PAS and must be converted to at least a TS 2028. The merging of Part 2, 3 and 6 will therefore also handle the necessary changes required to make former Part 6 more usable with limits and requirements.
