25) Softening Point of Bitumen | Asphalt | Road Surface

Softening Point of Bitumen. Introduction: Bitumens are viscoelastic materials without sharply defined melting points; they gradually become softer and less viscous as the temperature rises. For this reason, softening points must be determined by an arbitrary and closely defined method if results are to be reproducible. The softening point is useful in the classification of bitumens, as one ...

(DOC) BITUMEN –A VERY VERSATILE CONSTRUCTION …

Consistency of bitumen can be judged by some empirical tests such as penetration, softening point, ductility etc. and also by testing the fundamental property of bitumen such as viscosity. 7.1.2 Purity : It is the property by which it is checked, whether any impurities in form of organic materials or other impurities present in the bitumen or not. This is checked by the solubility of bitumen ...

ASPHALT TESTING LABORATORY MANUAL

To determine the softening point of bitumen within the range 30 to 157 . o. C by means of the Ring-and-Ball apparatus. BACKGROUND . Unlike some substances (e.g. water which changes from solid to liquid at 0 . o. C) bituminous materials do not have a definite melting point. Instead, as the temperature rises, these materials slowly change from brittle or very thick and slow-flowing materials to ...

Softening point of bitumen | Matest

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 softening point is reported as the mean of the temperatures at which the two disks soften enough to allow each ball, enveloped in bitumen, to fall a distance of 25 mm (1.0 in.). The softening point is useful in the ...
