Evaluation of Bituminous Concrete Using Ceramic Waste as a Filler

The functional qualities of asphalt are greatly influenced by filler, which is a key ingredient in the asphalt mixture. Filler materials have the property of filling the voids between coarse aggregate and binder and improves the bond. The qualities of an asphalt mix may change if the type and quantity of filler is altered. One of the most significant building and demolition wastes with a very low potential for recycling are ceramic materials. The accumulation of ceramic waste and pavement damage can be prevented by adding ceramic waste powder as a modifier to bituminous mixture. This research aims to evaluate the effects of using ceramic dust as filler material in bituminous concrete with 25, 50 and 75% contents by total weight of the fines using conventional crushed rock fines as control material. The research work is oriented in comparing the performance of bituminous concrete using laboratory tests including Marshall stability and flow with corresponding volumetric parameters. The analysis of results proved that the value of Marshall stability was improved at all replacement ratios of the ceramic, an overall increase of 22.2% was obtained with 75% ceramic dust. This attempt not only has the potential to significantly reduce the amount of trash, but it will also reduce the usage of non-renewable resources like natural filler and in effect improves strength of flexible pavement.
