AS 2341.18:2020 PDF Download

AS 2341.18:2020 standard aims to provide guidelines for determining the softening point of bitumens and related roadmaking products using the ring and ball apparatus. The standard specifically applies to materials with a softening point ranging from 30 °C to 157 °C.

The standard outlines two procedures for conducting the softening point test. These procedures involve heating a sample of the material in a ring and ball apparatus and determining the temperature at which the sample softens and two spheres placed on top of the sample touch. The first procedure is applicable to materials with softening points above 80 °C, while the second procedure is suitable for materials with softening points below 80 °C.

By providing a standardized method for determining the softening point, the standard ensures consistency and accuracy in the evaluation of bitumens and related roadmaking products. This information is vital in the construction and maintenance of road surfaces, as the softening point indicates the temperature at which the material may deform under load. Compliance with this standard enables reliable assessments of the suitability and performance of bitumens and roadmaking products for various road conditions.
