Pulverized Ceramic Tile Waste as Potential Mineral Filler in Hot Mix Asphalt

抄録

This study evaluated the properties of hot mix asphalt (HMA) with pulverized ceramic tile wastes (CTW) to serve as mineral filler for HMA. The physical properties of the HMA with pulverized CTW, were compared to the properties of HMA conventional mix and HMA with fly ash. The properties evaluated include the specific gravity, bulk specific gravity, theoretical maximum density, flow and the void ratio. Results showed that the stability of the HMA with pulverized CTW is higher than the other HMA mixtures. This indicates the increased resistance to horizontal deformation for the HMA with pulverized CTW. In addition, a slight reduction of the flow property of the HMA with pulverized CTW, shows that the vertical deformation did not have much effect when the type of mineral filler is changed. Air voids, and other properties including the bulk specific gravity and maximum theoretical density, are well within the range of the Philippine Department of Public Works and Highways (DPWH) specifications for roads and highways. Results show the potential of using pulverized CTW as replacement mineral filler for HMA.
