Overview
This European Standard describes a test method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples. The samples used are either produced in a laboratory or are drill cores taken from the site. This procedure was previously known as Wehner and Schulze method. The body responsible for this standard is NA 005-10-10 AA "Asphalt (SpA zu CEN/TC 227/WG 1) Gemeinschaftsausschuss mit FGSV" ("Bituminous mixtures (national mirror committee for CEN/TC 227/WG 1), Joint working group with FGSV") at DIN.
Please get in touch with the relevant contact person at DIN if you have problems understanding the content of the standard or need advice on how to apply it.
