Asphalt is typically stored and transported at temperatures around 150 176 C 302 176 F Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity upon delivery these lighter materials are separated out of the mixture This mixture is often called bitumen feedstock or BFSThis method can be used for the determination of bitumen ratio or asphalt content of hot mix asphalt paving mixtures and pavement samples for quality control specification acceptance and mixture evaluation Bitumen ratio is the ratio of the weight of asphalt to the dry weight of aggregate in an asphalt mixture
