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

Bituminous mixtures - Test methods for hot mix asphalt - Part 4: Bitumen recovery: Fractionating column

Scope

This European Standard 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 cutback bitumen but the results may be less precise. NOTE: There is limited experience of recovery when polymer-modified bitumen is used.
