摘要
为研究沥青组分对粘附性的影响,基于沥青四组分及沥青与粗集料的粘附性试验数据,利用灰关联方法分析了沥青质、芳香分、饱和分、胶质、胶质与沥青质含量之和、胶质与沥青质含量之比等因素对沥青与花岗岩及玄武岩两种典型集料粘附性能的作用关系,得出各因素的灰关联度排序结果。结果表明,灰关联方法用于分析各沥青组分因素对沥青与粗集料粘附性能的影响能获得较好的结果。胶质含量对沥青与石灰岩和玄武岩的粘附率与粘附性等级具有较高的影响程度;胶质含量愈多,对沥青与集料的粘附性影响程度愈高。胶质与沥青质之比对粘附性指标具有较低的影响程度。为提高沥青与集料的粘附性能,对于不同酸碱性质的集料,选择沥青时应注意不同组分的比例关系。
In order to know the influence of asphalt components on asphalt-aggregate adhesion, based on the test data of asphalt four components and asphalt-aggregate adhesion, with the grey incidence analysis, the influences of asphaltene, aro matic, saturate, resin, total content of resin and asphahene, content ratio of resin and asphahene, and other factors on the adhesion between asphalt and lime stone and basalt were analyzed, the sorted results of gray relational degree of each factor also were drawn. The experimental results show that satisfied results can be got while the grey incidence analysis is used to study asphalt components and asphalt-aggregate adhesion. The resin content has more influence on adhesion of lime stone and basalt, the more the resin content is, the higher the asphalt^aggregate adhesion is. The ratio of resin and as- phahene has the lower influence on the adhesion. In order to improve the asphalt aggregate adhesion, for different acidbase aggregates, it should be paid attention to the ratio among different components when selecting asphalt.
