Figure : Bitumen Softening Point Test

A brass ring containing bitumen is suspended in a liquid medium (water or glycerin), and a steel ball is placed on the disc of bitumen. The liquid medium is then heated at a specified rate. The temperature at which the softened bitumen touches the bottom plate placed at a specified distance below the ring is recorded as the softening point. A bitumen of penetration grade 30/40 has a softening point of 50-65oC.
