The Influences of the Volume in Asphalt Foam Device on Foaming Asphalt Characteristics in Cold Foam Asphalt Recycling Equipment

摘要

In this paper, the structure of foam cavity which based on FB100 foamed asphalt testing machine will be analyzed and designed to change its volume. So that, the changes of work pressure about hot asphalt would be caused and the hot asphalt, water, gas would be more uniform contact to improve the effect of foaming properties about asphalt. The models were built with Fluent Software and large number of experiments were be done, the affection and the law of foaming asphalt characteristics which has changed when the volume of asphalt foam device was changed will be verified by analysis, the ideal range of volume about asphalt foam device cavity will be given.
