A complex combination of hydrocarbons obtained from the vacuum distillation of the products from a thermal cracking process. It consists predominantly of hydrocarbons having carbon numbers predominantly greater than C34 and boiling above approximately 495°C (923°F).
The softening point is measured using the ASTM D36 method. Bitumens have softening points in the range of 30 to 128°C.
For complex hydrocarbon substances like bitumen, a melting point is not a meaningful parameter, since they become gradually softer as the temperature rises. The softening point, measured using ASTM method D36/EN 1427, is normally used to describe this property. For penetration grade bitumens, the values are mandatory and are specified in CEN technical specifications (CONCAWE 1992a; Shell 2003). Some grades of bitumen are too soft to measure the softening point according to available methods, which do not allow measurement below 5°C. In theory, values for these grades could be calculated but instead, viscosity is measured beginning at 60°C.
