| 摘 要： | 沥青路面车辙是当前高速公路路面的最主要早期损坏形式。该文通过沥青动态剪切流变试验、重复蠕变试验、粘度试验及混合料的车辙试验,对硬质沥青、改性沥青和70#沥青的高温性能做出全面比较分析;依托高速公路硬质沥青试验路工程的建设,对试验路抗车辙性能进行了调查。结果表明硬质沥青的高温性能较为优越,其长期效果仍有待进一步检验。

| Abstract: | At present, the rutting is the primary early damage of asphalt pavement expressway. With the help of dynamic shear rheometer (DSR), repeated creep test, viscosity test, as well as rutting test of asphalt mixture, this paper deeply analyzed and compared the high temperature performance of the hard asphalt, the modified asphalt and the 70# asphalt. At the same time, trial roads were built to survey the anti-rutting performance of different asphalts. The results showed that the hard asphalt performs better at ... |
