The scope of the study is to evaluate the laboratory performance of two asphalt mixtures; one modified with SBS polymer and the second modified with a polymer from Honeywell. Both asphalt binder and mixture properties are proposed to be evaluated in the study. Laboratory asphalt mixture tests are proposed to evaluate the overall performance of the asphalt mixtures developed using the two asphalt binders modified with the Honeywell polymer and the SBS polymer.
