DIN EN 12697-4
Bituminous mixtures - Test methods - Part 4: Bitumen recovery: Fractionating column; German version EN 12697-4:2015
Asphalt - Prüfverfahren - Teil 4: Rückgewinnung des Bindemittels: Fraktionierkolonne; Deutsche Fassung EN 12697-4:2015
Overview
This European Standard specifies a test method for the recovery of soluble bitumen from bituminous mixtures from pavements in a form suitable for further testing. This procedure is suitable for the recovery of paving grade bitumen and is also suitable for mixtures containing volatile matter such as cut-back bitumen but the results may be less precise. This European Standard is the reference method for mixtures containing volatile matter, but the rotary evaporator procedure (see EN 12697-3) for mixtures with paving grade bitumen. The mirror committee responsible for this standard is NA 005-10-10 AA "Asphalt (SpA zu CEN/TC 227/WG 11) Gemeinschaftsausschuss mit FGSV" ("Bituminous mixtures (Mirror Committee of CEN/TC 227/WG 11) Joint committee with FGSV)") at DIN Standards Committee Building and Civil Engineering (NABau). There is limited experience of recovery when polymer-modified bitumen is used.
