AN EXPERIMENTAL INVESTIGATION ON EFFECT OF FILLER TYPE ON STONEMIX ASPHALT

STONE MATRIX ASPHALT – SMA, a gap graded mix, is extremely rut resistant, tough, stable, skid resistant, with high quantity of coarse aggregates, relies on stone to stone contact, to supply strength & rich in binder, to produce durability.This study examines three forms of industrial and by-product waste fillers, namely Stone dust, fly ash and wooden charcoal.To decrease the price and increase its workability and strength waste materials are used as filler. It consists of gap- graded mix comprising of aggregate continuously graded from maximum size, typically lesser than 19 mm, through the fine filler which is smaller than 0.075 mm.The quantity of fiber that's used during experiment is about 0.3% to 0.5% of the entire weight.The STONE MIX ASPHALT design aims to figure out the proportion of bitumen, filler, fine aggregates, and coarse aggregates to supply a mix which is workable, strong, durable and economical
