Bituminous Paving Mixes, Bitumen, Fillers, Brick Dust, Hydrated Lime, Optimum Binder Content, Marshall Properties


As we know that the fillers plays vital role in the bituminous paving mixes. It is not only fill up the voids but also increases the engineering properties of the bituminous mixture in great extent. For this only single conventional fillers are used such as stone dust, cement etc. An attempt has been made in this investigation to assess the feasibility of non-conventional and cheap fillers such as brick dust along with conventional fillers in bitumen paving mixes. This study deals with the combined effect of conventional and non-conventional fillers on the bituminous mixes for varying bitumen content of 4%, 5%, 6% & 6.5%. It has been observed as a result of this study that bituminous mixes with these conventional and non-conventional fillers result in satisfactory Marshall Properties though requiring a same bitumen content compare with the single conventional filler. These results also shows that bituminous mix containing [Brick dust + Hydrated lime] composite is suitable substitute to traditional filler and are acceptable materials for bituminous concrete of flexible pavement construction. Also, the optimum binder content is find out for this composite to satisfy economic consideration. The fillers used in this study are likely to partly solve the solid waste disposal of the environment.
