| 摘 要： | 高速公路由于行车密度大、车速快,对沥青路面的级配、抗滑性、平整度、耐高温、低温抗裂性等提出了更高的要求。而沥青上面层中的原材料性能是影响路面质量最直接的因素,因此,依托十堰—天水高速公路汉中东段路面工程,就SMA-13沥青上面层对材料的选择展开探讨,具有十分重要的工程意义。

| Abstract: | Because of the high density and high speed of traffic flow on expressway,the higher requirement on mixture gradation,slip resistance,smoothness,resistance to high temperature,lowtemperature crack resistance and other aspects of asphalt pavement is put forward. The materials＇ property of asphalt surface course is the most direct factor impacting pavement quality. Combining with the pavement engineering of Shiyan-Tianshui Expressway Hanzhong east section,the selection of materials for SMA-13 asphalt surface course is discussed,which has important meaning to engineering. |
