Softening point is that temperature at which the specimen under test becomes soft enough to allow a steel ball of specific dimensions to fall a required distance under test condition. The apparatus consists of glass beaker, ring Stand, two steel balls with rings and ball guides, hand Stirrer. Optional accessories. Thermometer ip 60c
The apparatus is suitable also to test coating mixtures and other materials different from bitumen. The softening point is the temperature at which a disk of the sample held within a horizontal ring is forced downward a distance of 25.4 mm under the mass of a steel ball as the sample is heated at a prescribed rate in a water or glycerine bath.
This apparatus used to determine the softening point of bituminous materials. Softening point is a temperature that the bitumen under test becomes soft enough. In that temperature, a steel ball is able to fall and travel between a certain distance. The steel ball has standard dimensions. The apparatus consists of glass beaker, ring stand, two ...
1- ASTM D36-95 (2005) “Standard Test Method for Softening Point of Bitumen (Ring and Ball Apparatus)”. 2- AASHTO T53-96 (2000) “Standard Method of Test for Softening Point of Bitumen (Ring and Ball Apparatus)”.
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). ...

Also called as Ring & Ball Apparatus. This apparatus is meant for determination of softening point of bituminous materials according to IP 58 and IS 1205. Softening point is that temperature at which the specimen under test becomes soft enough to allow a steel
Softening temperature. Softening point determination by the ring-and-ball method is intended to evaluate the behavior of bituminous binders at elevated temperatures of use. The essence of the ring-and-ball method is that a small metal ball is pressed against a bitumen sample, piercing it to 25 mm with the temperature increased.
