摘要
为了明确沥青组分等各因素对黏度的影响关系,测试了10种沥青结合料4组分及黏度试验数据,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135℃和100℃下黏度的灰关联度排序结果.结果表明,将灰关联方法用于分析各沥青组成成分因素对135℃和100℃下的黏度影响能获得较好的结果.各影响因素对沥青135℃黏度影响程度的排序由大到小依次为:胶质、芳香分、饱和分、胶质与沥青质含量之和、胶质与沥青质含量之比、沥青质.胶质含量对两个温度的沥青黏度均具有较高的影响程度,沥青质含量影响程度较低.分析表明,胶质含量、胶质与沥青质含量之和对沥青在较高温度下的黏度和施工过程中的技术性能具有重要影响.
In order to clarify the influencing relationship of asphalt components and other factors on the viscosity, four - component analysis data and viscosity test data of ten asphalt binders were tested. Based on the grey incidence analysis, the gray correlation degree sort results of asphaltene, aromatics, saturates , resin, total content of resin and asphaltene,the content ratio between resin and asphahene and other factors on the viscosity at 135 ℃ and 100 ℃ were analyzed. The research results showed that satisfactory results can be gotten when grey incidence analysis was used in studying the influence of asphalt components on the viscosity at 135 ℃ and 100℃. For the viscosity at 135 ℃, the grey relation sequence of influence factors is that resin content, aromatic content, saturate content, total of resin and asphaltene, ratio between resin and asphaltene, and asphaltene content. The sequence data got by the grey relation degree theory show that the resin content is the principal influence factor for the viscosity at both temperature, while the asphaltene content has a minimum influence. The analysis showed that resin content and total of resin and asphaltene have important effect on the viscosity with higher temperature in construction process and workability of asphalt binder.
