  • Softening Point | Asphalt | Temperature

    The softening point value has particular significance for materials which are to be used as thick films such as joint and crack fillers and roofing material. A high softening point ensures that they will not flow in service. For bitumen of a given penetration determined at 25°C the higher the softening point the lower the temperature sensitivity.

  • Standard Test Method for Softening Point of Asphalt and .

    4.1 Asphalt and pitch do not go through a solid-liquid phase change when heated, and therefore do not have true melting points. As the temperature is raised, they gradually soften or become less viscous. For this reason, the determination of the softening point must be made by an arbitrary, but closely defined, method if the test values are to be reproducible.

    Asphalts do not have an exact melting point since they are neither crystalline nor chemically homogeneous. As such, the softening point is simply an arbitrary indication of the resistance to flow at rooftop temperatures. Typically, unmodified paving grade asphalt binders will have softening point temperatures in the range of approximately 35-55 .

    With SBS-modified bitumen, the softening point is more than adequate for roofing purposes, and the cold temperature flexibility dips below -20F(-28C). The elongation and recovery (elasticity) properties of SBS-modified bitumen are far better than other bituminous materials, as the modified bitumen acts more like the SBS rubber modifier.
