Bituminous mixtures. Test methods -- Bitumen recovery. Fractionating column
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.
There is limited experience of recovery when polymer-modified bitumen is used.
