| 摘 要： | 沥青的化学组成决定了沥青的使用性能,但是沥青部分物化性能的测定属条件试验,由于在具体试验过程中没有严格按照操作条件进行,导致沥青的化学组成与其使用性能关联性较差.研究通过对比试验,考察了石油沥青组分测定过程中氧化铝的水含量、沉淀沥青质所用溶剂的用量以及冲洗剂的用类等对测定结果的影响.试验结果表明:石油沥青组分测定法是条件试验,改变试验条件将会影响试验的测定结果.

| Abstract: | The performance of asphalt is related to its chemical composition;however this relevance depends mainly on the determination of chemical constitution under the defined terms.So the determination conditions of chemical composition of asphalt are very important to predict the asphalt's performance correctly.The influences of the water content in alumina,the amount of solvent,and the volume of rinsing solvent on the determination of four components of SARA were investigated in detail.The results showed that th... |
