How to test water content of bitumen

Tesing of water content of bitumen 60/70 ,40/50 and bitumen 80/100

It is desirable that the bitumen 40/50 , 60/70 and bitumen 80/100 contains minimum water content to prevent foaming of the bitumen 40/50 , 60/70 and bitumen 80/100 when it is heated above the boiling point of water. The water in bitumen 40/50 , 60/70 and bitumen 80/100 is determined by mixing known weight of specimen in a pure petroleum distillate free from water, heating and distilling of the water. The weight of the water condensed and collected is expressed as percentage by weight of the original sample. The allowable maximum water content should not be more than 0.2% by weight.
