| 摘 要： | 研究了改性沥青黏度、黏韧性与苯乙烯系嵌段共聚物(SBS)和增黏树脂用量之间的规律,制备了高黏度改性沥青并应用于工程。结果表明,随着SBS用量增加,沥青动力黏度和运动黏度快速增长,黏韧性先增加后降低;增黏树脂能够提高SBS改性沥青动力黏度,降低运动黏度,提高黏韧性。高黏度改性沥青制备的沥青混合料具有优异的性能。

| Abstract: | This paper studied the laws between modified asphalt viscosity, adhesion toughness and the dosage of styrene block copolymers （SBS）, and tackifying resin. It also prepared the high viscosity modified asphalt and was applied to the engineering. It came to the conclusion that the asphalt mixture with high viscosity modified asphalt preparation had excellent performance. |
