| 摘 要： | 为了解决西部地区沥青路面的横向开裂等主要病害,对西北地区常用的克拉玛依基质AH 110#沥青及AH 90#沥青使用SBS4303,1401,1301改性剂进行了室内改性试验.结果显示,影响SBS改性沥青性能,特别是低温性能的主要因素为基质沥青的性质、组分的比例,其次为改性剂的型号和剂量;优良的基质沥青并不能通过SBS改性达到适合于本地区改性沥青的技术要求.

| Abstract: | In order to solve the transversal crack of pavement in the west region of China, the modifiers of SBS4303, 1401, 1301 are used for modifying two kinds of Kelamayi asphalts (AH-110~#, AH-90~#) which are commonly used in the region. The properties of the modified asphalts are studied. The results show that, the key factors of influencing their properties are the property of the crude asphalts and the ratios of their components; the secondary factors are the types and the dosage of SBS modifiers. It is also shown that the crude asphalt of good properties cannot reach to the technical standards required in the region by SBS modifiers. |
