Title (German)

Bitumen und bitumenhaltige Bindemittel - Bestimmung der Beständigkeit gegen Verhärtung unter Einfluss von Wärme und Luft - Teil 1: RTFOT-Verfahren; Deutsche Fassung EN 12607-1:2014

Overview

This document specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder simulating the hardening which most bituminous binders undergo during mixing in an asphalt mixing plant. The method described is not applicable to some modified binders or to those where the viscosity is too high to provide a moving film. In some cases the sample may creep out of the glass container and flow on the heating elements of the oven during testing. The method is suitable for other bituminous binders than paving grade bitumen, but the reference temperature might give excessive hardening that do not resemble real conditions during mixing at the plant. The method may not represent the hardening that occurs during mixing of warm mix binders. The method is referred to as RTFOT, that is Rolling Thin Film Oven Test. This document has been prepared by Technical Committee CEN/TC 336 "Bituminous binders", the secretariat of which is held by AFNOR (France). The responsible German committee is Joint Committee NA 062-03-32 GA "Bitumen; Prüfverfahren und Anforderungen für die Bindemittel" ("Bitumen; test methods and specifications of binders") of the Materials Testing Standards Committee (NMP) and of the Building and Civil Engineering Standards Committee (NABau).
