Title (German)
Asphalt - Prüfverfahren für Heißasphalt - Teil 49: Messung der Griffigkeit nach Polierung; Deutsche Fassung EN 12697-49:2014
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.
