Përzierje bituminoze - Metodat e provave- për përzjerjen e asfalto-betonit të nxehtë - Pjesa 4: Rikuperimi i bitumit: Kolona e fraksionimit

Bituminous mixtures - Test methods - Part 4: Bitumen recovery: Fractionating column

Scope

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.
