| 摘 要： | 粉煤灰代替石灰石矿粉作填料拌制沥青稳定碎石混合料,采用大马歇尔试验方法进行室内对比试验。试验结果表明,利用粉煤灰代替石灰石矿粉作填料的沥青混合料各项技术指标均能达到规范要求。因此,从提高沥青混合料路用性能角度出发,将粉煤灰作填料应用到沥青稳定碎石基层中具有一定的可行性。

| Abstract: | This paper introduces that fly ash is used as packing to mix the asphalt stabilized gravel mixture in- stead of limestone mineral powder, and the large-scale Marshall test method is adopted in indoor comparison test. The test result shows that all technical indexes of asphalt mixture filled with fly ash instead of limestone powder meet the requirements of specification. Therefore, the fly ash used as packing to apply into the asphalt stabilized gravel base possesses a definite feasibility in order to promote the pavement performance of asphalt mixture. |
