Published By | Publication Date | Number of Pages |
DIN | 2022-04 | 36 |
This document specifies a method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples, or to follow its evolution as a function of the number of polishing passes. The samples used are either produced in a laboratory or are cores taken from the site.
