This European Standard (EN 12697 4:2014) describes 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.
