Device and method for quickly recovering waste asphalt from waste asphalt pavement material
The invention relates to a device and a method for quickly recovering waste asphalt from a waste asphalt pavement material, is used for quickly extracting asphalt from the waste asphalt pavement material, is beneficial to a method for accurately measuring recovered asphalt property indexes and belongs to the field of road material engineering. According to the novel method for quickly recovering the waste asphalt, through research and comparison, the vacuum negative-pressure technology is used, filtration and distillation systems are based on an airtight system, quick filtration and distillation are performed, the distillation temperature is reduced, CO2 is used as vacuum negative-pressure shielding gas to reduce asphalt oxidation and test danger coefficients, the technical problem that impurities and trichloroethylene solvents exist in recovered asphalt is solved effectively, so that the recovered asphalt property indexes can be measured accurately, and a foundation is laid for recycling the waste asphalt pavement material more scientifically and reasonably in the later period.
