粉煤灰及钢渣在冷再生混合料中的应用

在乳化沥青冷再生混合料中使用5种不同剂量的粉煤灰和钢渣来取代部分水泥,研究其对混合料相关路用性能的影响。结果表明:1)粉煤灰替代量为25%时,其马歇尔强度有所提升,其余路用性能均有所下降,建议控制量在25%以内;2)添加钢渣后,混合料的所有性能均有所下降,要严格控制钢渣的替代量在40%以内。

Application of Fly Ash and Steel Slag in Cold Recycled Mixture

Five different dosages of fly ash and steel slag were used to replace some cement inemulsified asphalt cold recycled mixture,and the influence on the road usage performance of the mixture was studied.The results show that when the replacement amount of fly ash is 25%,the Marshall strength is improved,and the other road usage performances are reduced.It is suggested that the control amount should be less than 25%.After adding steel slag,all the properties of the mixture are reduced;the replacement amount of steel slag should be strictly controlled within 40%.
