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.<\/p>\n
