摘要
本文为评价90号石油沥青在储存过程中的老化行为,将90号石油沥青在130℃和170℃温度条件下储存时间从0h~68h,根据沥青的技术指标和试验结果,分析沥青性能的变化情况以及沥青各技术指标的抗老化性能,在此基础上,给出了90号石油沥青的高温储存建议。
In this paper,to evaluate the aging behavior of No.90 petroleum asphalt during storage,the No.90 petroleum asphalt was kept under the temperature of 130℃ and 170℃ from 0 h to 68 h,according to the technical index and test results of asphalt,the changes of asphalt performance and aging resistance of various asphalt technical indicators were analyzed,on this basis, the storage time requirement of No.90 petroleum asphalt was determined.
