Determining Softening Point Of Bitumen - Civil Engineering

This test is done to determine the softening point of asphaltic bitumen and fluxed native asphalt, road tar, coal tar pitch and blown type bitumen as per IS: 1205 – 1978. The principle behind this test is that softening point is the temperature at which the substance attains a particular degree of softening under specified condition of the test.

SOFTENING POINT OF BITUMEN (IS:1205:1978)

Sample material is heated to a temperature between 75° and 100°C above the approximate softening point until it is completely fluid and is poured in heated rings placed on the metal plate. To avoid sticking of the bitumen to metal plate, coating is done to this with a solution of glycerin and dextrin.
