Heat the sample with care, stirring when possible to prevent local overheating, until it has become sufficiently fluid to pour. In no case should the temperature be raised to more than 90 °C above expected softening point for petroleum asphalt (bitumen). Do not heat samples for more than 30 minutes.
Web26 Sep 2024 · Bitumen aging leads to a decrease in penetration and an increase in softening point value over time. For the Zaca-Wigmore Test Road (US), a limit value of 30 was stated for penetration (originally 100–200) as a pavement end-of-life criterion, although lower values were found in extracted bitumen from other test roads with little or no cracks ... Web3 Dec 2024 · To determine the Softening point of given bituminous material. Theory and Scope The softening point is the temperature at which the bitumen attains a particular degree of softening under the specified condition of the test.
