摘要
采用环烷基原油生产的沥青为原料,分别添加三种不同类型的增黏剂进行试验。考察了三种增黏剂对不同油源生产的沥青产品性能的影响,得出了不同增黏剂应用于不同沥青时沥青性能的变化规律。针对不同原油生产的沥青筛选出与之配伍的增黏剂,确定了适宜的工艺条件及配方,使沥青的动力黏度得到显著的提高。
The experiment had been done with three different types of viscosity enhancing admixtures （VEA） and the asphalt produced from naphthenic base crude oil. The effects of the three VEAs on the performances of asphalt produced from different crude oils had been observed. A pattern of variation on the performanee when different VEA was used in different asphalt had been obtained. Suitable VEA had been selected for different asphalt produced from different source. Appropriate process and formula had been settled and the dynamic viscosity had been enhanced greatly.
