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.
