| Abstract: | The solvent extraction method was adopted to enrich the water sensitive component in asphalt.Using the method of infrared spectroscopy,the structural units in the water sensitive components were identified,and the influencing factors for moisture damage-component were investigated.By simulating the pavement serving process and the aging in the construction process,the changing rules of water sensitive component in asphalt were studied.The results show that CS2 could completely extract water sensitive compon... |
