SOFTENING POINT TEST ON BITUMEN
Objective:
To determine the softening point of the given sample of bitumen.
Apparatus used:
Ring and Ball Apparatus, Water Bath with Stirrer, Steel Balls, Bunsen Burner.
Description Softening point of Bitumen: Denotes the temperature at which the bitumen attains a particular degree of softening under the specifications of test.
The bituminous material is heated to a pouring temperature and is poured into the rings on a metal plate.
Metal plate is coated with a mixture of equal parts of glycerine and dextrin.
Assemble the apparatus in position.
Fill the beaker with distilled water to a height of 50mm above the upper surface of the rings.
Assemble the apparatus with the rings, stirrer and ball guides in position.
Heat the water bath and stir the liquid so that the temperature rises at a uniform rate of 5 ± 0.5 °C per minute.
