In this paper summary of the ongoing research papers concerning the effect of various fillers on bituminous mixes was reviewed. Depending upon the particle size fines can act as filler or extender of bitumen binder. Filler particles should be passed through 0.075mm sieve. Filler may be added in different range expectedly from 2% to 4% in bituminous concrete. When the quantity of filler increases in the mix, the Marshall properties of the bitumen mix may also improve directly up to certain

... . It was concluded that various fillers such as carbon black, fibres, rubbers, polymers, fly ash, silica or their combination may have different effects on properties of mix that is rutting behaviour, ageing characteristics and stripping behaviour etc. Filler makes mix stiffer, moisture resistant and durable etc.
