| 摘 要： | 该文针对目前应用较少的SMA25粗粒径沥青混凝土进行配合比设计,通过级配实验确定了合理的级配组成,并对最佳油石比进行了性能验证,与细粒径SMA13进行了性能对比,发现粗粒径SMA25具有更高的抗车辙能力,在较小油石比的情况下获得更好的路面性能。

| Abstract: | Aiming at SMA25 coarse asphalt concrete applied a few now,the article designs the mixture ratio,validates the performance of the optimized oil and stone ratio by the gradation experiment to define the reasonable gradation composition,and compares the performance of the fine SMA13.The result shows that SMA25 has the higher rut-resistant capacity,and the better pavement performance can be achieved under the condition of the smaller oil and stone ratio. |

| Keywords: | large-stone design of mixture ratio rut-resistant performance gradation |
