【摘要】 大粒径沥青混合料由于其一般应用于基层,处于受拉的应力状态,在荷载的反复作用下,易产生疲劳断裂破坏。本文从级配、沥青用量、温度、沥青种类和格栅加筋等方面对大粒径沥青混合料的疲劳性能进行了研究,得出一些有参考价值的结论。更多还原

【Abstract】 To minize or eliminate rutting of heavy duty asphalt pavement, large stone asphalt mixture has been brought forward. Used on base, it s easy to produce fatigue crack under reiterated traffic load. So fatigue performance of large stone asphalt mixtures with different grading, asphalt dosage, temperature, asphalt and grid has been researched in this paper.更多还原
