    This paper presents a comprehensive study on the use of recycled industrial and agricultural wastes converted to powder and used as fillers in asphaltic concrete production.Fillers are essential components of an asphaltic concrete as they not only fill voids in the coarse and fine aggregates but also affect the ageing characteristics of the mix.The study in evaluating the effect of different types of filler on the behavior of asphaltic concrete used broken bricks powder, broken tiles powder, cow bone ash and broken glass powder as fillers. Marshall stability and flow test were carried out on the asphaltic concrete samples. The materials used in this study include 60/70 penetration grade bitumen, river sand and crushed granites. The average marshall stability and flow values of the broken bricks powder, broken tiles powder, cow bone ash and broken glass powder is obtained as 12.21 KN, 12.51 KN, 10.75 KN and 16.05 KN for the stability and 3.10 mm, 3.06 mm, 2.69 mm and 3.28 mm for the flow respectively. This shows that broken glass powder has the highest marshall stability and flow value. The study concluded that the fillers have varying effects on the asphaltic concrete properties (rutting behavior, ageing characteristics, stripping behavior, stiffness, moisture resistance and durability) on judging from their varying marshal stability and flow values.
