机场改性沥青性能影响因素研究

Study on the Effect Factors of Airport Modified Asphalt Performance

对制备机场改性沥青的原料和工艺条件等因素进行研究,考察各因素对改性沥青性质的影响。结果表明,采用110号沥青和21%~27%芳烃油为原料,加入4.8%~5.2%的6302LSBS改性剂,在一定温度下,经过7~8 h发育反应,可以制备出稳定性好、PG高温等级为82℃的机场改性沥青。

In this study,the raw materials and technological conditions for preparing airport modified asphalt are studied to investigate effect factors on the performance of modified asphalt. The results show that the airport modified asphalt with good stability and PG high temperature grade of 82 ℃ can be prepared by using110#asphalt and 21-27% aromatic oil as raw materials,adding 4.8-5.2% 6302 LSBS modifier and after 7-8 h development reaction at a certain temperature.
