| 摘 要： | 以70#沥青作为基质沥青,对不同种类和掺量的岩沥青改性沥青的高温抗车辙能力进行了研究,基于3种车辙试验的试验结果表明,随着岩沥青掺量的增加,改性沥青的高温抗车辙能力得到提高;同时得出选用优质的岩沥青种类比掺入大量的岩沥青更重要的结论,从而为岩沥青的应用提供了参考。

| Abstract: | In this paper,a series of rutting tests of the asphalt mixtures with different types and contents rock asphalt based asphalt 70 # were made at high temperature.Based on the results of three kinds of rutting tests,the experiments indicated that the stability at high temperature of the rock asphalt mixtures is markedly increased.They also show that it was more important to choose high quality rock asphalt than to use high-contents rock asphalt.All of these conclusions are helpful to the use of rock asphalt. |
