摘要
利用元素分析、族组成分析和结构族组成分析方法 ,研究了辽曙沥青的组成与结构。建立了辽曙沥青组成与结构和使用性能之间的关系。辽曙沥青碳氢含量在 95%以上 ,氢碳原子比在 1 .5左右 ;辽曙沥青平均分子全部是多环结构 ,每个平均分子中约含有 4 5个碳原子 ,其中芳碳数为 1 6~ 1 7个 ;总环数为 5~ 6个 ,其中芳环数为 3~ 4个。辽曙沥青的沥青质含量在 8%~ 1 0 %之间、胶质含量在 2 5%~ 3 0 %之间、芳香分含量在 3 5%~ 4 0 %之间、饱和分含量在 2 0 %~ 2 5%之间的族组成使沥青具有良好的性能。
The characteristics of Liaoshu paving asphalts were analyzed by the means of element analysis,SARA and E-D-M And the relation between composition & structure and using performance of Liaoshu asphalt was established The experimental results showed that carbon and hydrogen content in the blending paving asphalts were more than 95%,hydrogen/carbon atom ratio was about 1 5 Liaoshu asphalt average molecule contains only multicycle structure There were about 45 carbon atoms in asphalt average molecule,which contain 16~17 aromatic carbon atoms The number of total cycle in asphalt average molecule was 5~6,in which aromatic cycle was 3~4 For Liaoshu asphalts,the optimum chemical composition is put forward
