Test Before Using Bitumen Drum Decanting Equipment

Heating and filtering the bitumen sample, adding the required ratio of anti-stripping agent, stirring by hand or agitator, so that the anti-stripping agent is evenly dispersed in the bitumen sample; the sample is subjected to film heating test for heating aging, using water ingress or water Test the adhesion between bitumen and coarse aggregate.

The adhesion test can be carried out using the bitumen binder test without film heating aging, or the water stability test using the bitumen mixture without aging treatment to compare to determine the heat resistance performance and long-term use effect of the anti-stripping agent.

Accelerated aging treatment was carried out on hot-mixed bitumen mixtures with anti-stripping agents; the immersion Marshall test and dynamic capacity split test of the mixtures were conducted to evaluate the water stability of the bitumen mixtures.

These are the main experimental methods of bitumen decanter equipment, and reasonable operation should be carried out according to the instructions, so that its performance can be fully demonstrated and used.
