摘要：Stone Matrix Asphalt (SMA) is a gap graded mix; characterized by higher proportion of coarse aggregate,lower proportion of middle size aggregate and higher proportion of mineral filler.The prime advantage of Stone matrixasphalt (SMA) is its ability to provide more durable surfacing, as well as its high resistance from damage due to heavyaxel loads. However, the initial cost for preparation of SMA is more than the other common asphalt mixes. On theother hand, the utilization of waste and by-products in the construction is still limited, especially in developingcountries like India.Agricultural wastes i.e. wheat straw is mostly burnt that cause’s environmental pollution .Utilizingagricultural waste for construction will not only reduce pollution but also reduce the overall construction cost. Thispaper reports about the experimental investigations carried out on stone matrix asphalt mixes prepared by using wheatstraw fibres with VG 30 grade bitumen.Marshall Procedure has been followed to determine the optimum binder andalso to study the relative advantages of fibre addition in the SMA mixtures. From the test results it was observed thatstone matrix asphalt mix with wheat straw fibre shows better performancethan stone matrix asphalt mix without fibre.It was also observed that SMA Mix with wheat straw fibre worksout cheaper and abundantly available.
