This standard 22/30448481 DC BS EN 12697-4. Bituminous mixtures. Test methods is classified in these ICS categories:
  • 93.080.20 Road construction materials
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. The 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. NOTE There is limited experience of recovery when polymer-modified bitumen is used.
