Effect of Almond Ash as Partial Replacement of Lime Filler on the Performance of HMA

Ever-growing concern to protect the environment focused on the attention of the society on the possible reprocessing of different agricultural and industrial wastes in road construction. This research looks at the effect of using wastes like almond leave ash (ALA) as partial replacement of conventionally used Quick lime (QL) as fillers in hot-mix asphalt (HMA). Primarily, the hot mix asphalt (HMA) specimens were made in the laboratory with varying proportions ranging from 0.5% to 4.5% of Quick lime by following design mixes according to the Marshall method and the results were compared with control mix as prepared by utilizing 7% QL. The performances of the said mixes were studied through the Marshall test. Results of investigation show better performance of HMA with the addition of ALA and QL at a ratio of 1.8 (i.e 4.5% almond leave ash and 2.5% Quick lime) this is mix ratio that satisfy the marshal criteria for medium and light traffic
