Storage stability test of emulsified bitumen
The objective of this test is to determine the storage stability of emulsified bitumen so as to understand the storage time of emulsion before becoming expired.
This test takes 24 hours to run.
First, we pour 500cc of the emulsified bitumen into this cylinder and keep it in the same state for 24 hours. Then, we take 50cc from the top and 50cc from the bottom of the sample and place them in beakers. We weigh them and place both samples inside the oven and adjust the heat to 163°C. After 3 hours, when the water is separated from the bitumen, we take the samples out of the oven, let them cool down and weigh them again. The difference between the two measured weights should not exceed 1 unit.
