Mixing temperature of bitumen
Webunlike normal hot bitumen, foamed bitumen has a temperature of only 50-60?C. Foamed-bitumen quality The main parameters determining the quality of the final foamed bitumen product are ‘expansion’ and ‘half-life’. WebBitumen is specified by the penetration and softening point test. Bitumen Penetration Grade 60/70 is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method.
