| 摘 要： | 通过旋转薄膜烘箱试验,研究SBR改性沥青和基质沥青在不同老化温度、老化时间下的软化点变化规律,并以软化点为参数建立了SBR改性沥青老化动力学模型,以此研究SBR改性沥青的老化动力性能.研究表明以软化点为参数建立的沥青老化动力学方程能够较好的反映沥青的老化过程.

| Abstract: | The rolling thin film oven test was used to study the changes laws of softening point of SBR modified asphalt along with the aging temperature and aging time.Based on parameter of softening point,aging dynamic model was established to research the aging dynamics performance of SBR modified asphalt.The study indicates that the anti-aging performance of SBR modified asphalt is better than that of base asphalt,the aging dynamic model that based on parameter of softening point could express the aging process of... |
