This test method describes the procedure for determining the degree to which a joint sealant is degraded by heat during prolonged storage (6 hours at 190 °C). It involves placing a joint sealant sample into an oven at elevated temperature and, after a prescribed time, measuring the change in softening point that has occurred during prolonged heating.
This test method can also be downloaded as a Word document.
Edition 2.0 published August 2022
- Commentary section aligned with other Austroads binder test methods.
- Reference, equipment, procedure and reporting sections revised so that tests are performed using a fan-assisted oven (rather than using a hotplate and glass beaker) and test results are calculated using the measured change in softening point results.
- Added calculation and precision sections.
