粉煤灰代替矿粉拌制沥青混合料的试验研究

粉煤灰作填料拌制沥青混合料,采用大马歇尔试验方法进行室内试验.结果表明:粉煤灰代替矿粉作填料的沥青混合料各项技术指标均能满足规范要求.因此,从合理利用资源、保护环境的角度出发,将粉煤灰应用到沥青混合料中具有一定经济效益和社会效益.

Experimental Research of Asphalt Mixture Making Fly Ash Instead of Powdered Limestone

Fly ash,serving as padding,was mixed into the asphalt mixture,and the test were performed by the big Marshall experiment in laboratory.The result showed that all the technical specification of bitumen mixture making the fly ash instead of powdered limestone could meet all the requirements for norms.Therefore,it owns certainly economic efficiency and social efficiency in terms of using resources reasonably and protecting environment by applying fly ash to bituminous mixture.
