| 摘 要： | 粉煤灰具有与石灰岩矿粉相近的物理化学特性,这为沥青混合料中粉煤灰替代矿粉提供了可能。以常用的AC—16沥青混合料为基础,采用三种不同掺量方法,测定马歇尔试验指标,研究表明:掺入粉煤灰后AC-16沥青混合料的马歇尔稳定度和密实度得到了提高。

| Abstract: | Fly ash has similar physical and chemical properties with ore powder,which makes it possible to be an alternative powder of the asphalt mixture.Based on the commonly used AC-16 asphalt,we test three diffe-rent dosage methods and measure the Marshall test indicators.Results of the study show that incorporation of fly ash increases the Marshall stability and density of asphalt mixture. |
