  • To Determine the Softening Point of Bitumen

    Bitumen is viscous elastic material without sharply defined melting points. They gradually become softer and less viscous as the temperature rises. This is the reason why the softening point of bitumen is determined. Softening point is not a melting point, bituminous material do not melt but instead gradually change from semi solids to liquids on application to heating.
