Pour the melt into the container to ...

The average temperature, at which each of the two tablets is softened enough to allow the balls to sink into them by 25 mm, is reported as the softening point of bitumen. See the Standards and Instructional Videos section for learning "How the Parsian Technology Group Devices Work".

softening point Bitumens are viscoelastic materials without sharply defined melting points; they gradually become softer and less viscous as the temperature rises. The softening point of bitumen can be determined through the use of a ring-and-ball apparatus immersed in distilled water (30 to 80°C) or USP glycerin (above 80 to 157°C).

Jan 22, 2018· To determine the softening point of asphaltic bitumen and fluxed native asphalt, road tar, coal tar pitch and blown type bitumen as per IS: 1205 – 1978.

whereas the 'ring and ball' method for the softening point determination involves putting a metallic ball of a defined weight onto the bitumen specimen that is embedded in a metallic ring. The softening point is defined in a heating run as the temperature where the bitumen specimen starts to deform under the weight of the ball. According ...

The softening point is the temperature at which a material softens beyond some arbitrary softness. It can be determined, for example, by the Vicat method (ASTM-D1525 or ISO 306), Heat Deflection Test (ASTM-D648) or a ring and ball method (ISO 4625 or ASTM E28-67/E28-99 or ASTM D36 or ASTM D6493 - 11 or JIS K 6863).
