Adjusted asphalt mixes enable the production of an asphalt binder with better viscoelastic characteristics that maintains balance over a wider temperature range and under more demanding loading conditions. Use of waste plastic adjusted bituminous binder is the solution to achieve the needed performing standards for the roads of today. It shows to be a reasonable, empirical, and economic way. This paper was made to estimate the impact of bituminous modifier on the mechanical properties of bituminous mixes. The traditional bituminous of penetration (40-50) in grade was utilized in the test, adjusted with waste plastic at five various adjustment levels in particular 0%, 2%, 4%, 6% and 8% by weight of bituminous. Bituminous mixes were equipped at choice optimum bituminous (4.5%) and then tested to assess their mechanical characteristics that comprise Marshall Properties, indirect tensile strength, resilient modulus and permanent. The mechanical features have been assessed utilizing uniaxial repeated loading test. From the practical findings, it can be found that the mixtures adjusted with plastic have indicated an enhanced permanent deformation properties besides superiority elastic characteristics as a distinguished by resilient modulus. The addition of 4 wp to the bituminous mixtures showed a clear improvement in the mixtures and create more permanent bituminous mixes with best serviceability.
