2. TO DETERMINE SOFTENING OF BITUMEN
OBJECTIVE
TO DETERMINE SOFTENING OF BITUMEN

3. PROCEDURE Bitumen is heated. Poured it in a pair of rings.
When bitumen is hard, placed the rings in a container filled with water at 5°C.
Two steel balls are placed on the rings and gradually heat the water container.
When temperature increases, the bitumen softens thus the balls which act as a weight, start to fall and land on the plate,25.4mm below.
The temperature at which the ball touches the plate is called softening point.

4. Softening point (SP) together with the Penetration value (P) are used to determine the Penetration Index (IP). IP can indicated the properties of bitumen tested and its suitability.
