One of the innovative technique of improvement in dense bitumen macadam surface practiced all over the world is addition of steel fibres in it. The performance of dense bituminous macadam Mixes with steel fibre in varied proportions (2%,2.5%,3%,3.5%,4%,4.5%,5%,5.5% & 6% with 18 mm and 11 mm length was studied by conducting Marshall Stability Test for Stability of Bituminous Mixes .The results have been noticed that the considerable improvement in stability of dense bitumen macadam was at an optimum percentage of added steel fibre for bitumen concrete at 3 % of 18 mm long steel fibre . Therefore these fibres content has been recommended for making improvements in parameter of Bituminous Mixes.
