| 摘 要： | 采用薄膜烘箱试验、低温吸氧试验、自然老化试验及反相气液色谱对国产典型的石油沥青及组分进行了老化和加速老化试验。根据沥青老化前后物化性质及其变化，如粘度比、吸氧量、凝胶渗析色谱峰扩展、族组成的变化、含氧基团的变化及老化综合指数等评价了国产沥青的抗老化性能。建立了沥青吸氧动力学模型。初步讨论了提高沥青耐久性的途径

| Abstract: | The ageing of domestic typical asphalt were performed by the thin film oven test(TFOT),the absorption of oxygen,the natural weathering and inverse gas liquid chromatography (IGLC)etc Durability of asphalts were evaluated based on the physico-chemical properties changes before and after ageing including the ratio of viscosity,the quantity of oxygen absorbed,the difference of GPC peak,the composition of SARA,the group of oxygen-contained and ageing comprehensive index of IGLC The kinetic model for the oxygen absorption of asphalt was given The pathway to improve the durability of asphalt were discussed |
