用辽河高粘原油生产重交通道路沥青的研究(Ⅲ)辽曙沥青组成与结构分析

THE STUDY ON PRODUCING HEAVY TRAFFIC PAVING ASPHALT BY USING HIGH VISCOUS CRUDE OIL FROM LIAOHE OIL FIELD (Ⅲ) STUDY ON THE COMPOSITION AND STRUCTURE OF LIAOSHU ASPHALT

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
