Web15 Jul 2013 · Harder paving grade bitumens have higher softening points, which makes the asphalt better able to withstand high summer temperatures. Melting tends to mainly only affect the top layer - known... Web6 Apr 2024 · Finally, note down the temperature at which the specimen touches the lower plate and this temperature is the softening point of the bitumen specimen. Normally the softening temperature varies from 35 degrees to 70 degree Celsius. Flash and fire point test.
Web31 Dec 2010 · 1.1 This test method covers the determination of the softening point of bitumen in the range from 30 to 157°C (86 to 315°F) using the ring-and-ball apparatus … WebSoftening Point of Bitumen. 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).

The test is conducted by using Ring and Ball apparatus. A brass ring containing test sample of bitumen is suspended in liquid like water or glycerin at a given temperature.
WebTraditional penetration value at 25°C and softening point temperature were used to monitor the ageing evolution of the binders from their initial condition through RTFOT ageing at 163°C, 143°C and 123°C and subsequent PAV ageing. Penetration is probably the simplest measure of bitumen’s properties. As bitumen is aged, its penetration decreases.
