| titleOfInvention | Separation method of four components of asphalt |
| abstract | The invention discloses a method for separating four components of asphalt, which adopts a solid phase extraction column method and combines an ultraviolet spectrometer to separate and measure the components of the asphalt so as to obtain the content of each component of the asphalt, the solid phase extraction column replaces a glass adsorption column, the dosage of an asphalt sample and an elution solvent is obviously reduced, the test speed is high, the solid phase extraction column is industrially and uniformly produced, is less influenced by human factors, has uniform and consistent component separation effect and has better reproducibility. According to the invention, through separation and determination of four components of the asphalt, on one hand, the research on an asphalt aging mechanism and a regeneration mechanism can be realized, and on the other hand, the improvement on a certain performance of the asphalt can be realized by adjusting the content of one or more components in the asphalt, so that the pavement performance of the asphalt mixture is improved, the operation is simple and convenient, and the asphalt mixture is suitable for wide popularization and application. |
