Bitumen recovery from bituminous mixtures using the rotary evaporator

In this Short Note we present the method for the recovery of soluble bitumen from bituminous mixtures. Bitumen is recovered from a toluenic solution according to the Swiss Standard SN 607 403a-NA by vacuum evaporation using a rotary evaporator after separation of the insoluble matter from recoverable binder. The two evaporation steps are performed in one hour only.
