Obtaining asphalt with rheological properties is suitable for different uses, especially the field of paving that has become a concern of researchers. Thus, many researchers have been keen on modifying asphalt by various additives, particularly polymeric additives. In our study, we modify the rheological characteristics of asphalt using a polymeric mixture of ethylene vinyl acetate (EVA) with styrene-butadiene rubber (SBR). The above polymeric mixture is used with different weights of both polymers, so that the sum of both polymers is equal to one. Then, we added the polymeric mixture to the asphalt with different percentages in the presence of (0.5%) by weight of anhydrous aluminum chloride as a catalyst for this process at a constant temperature of (150) ° C for one hour . We made many measurements made on the modified samples in addition to the original asphalt, including the Ductility, Penetration and Softening Point as well as calculating the penetration index and the percentage of the separated asphaltens . The modified pathway produced many samples with excellent rheological properties. The selected samples that have a good rheological properties are suitable for climates in our country (Iraq) . If obtained Marshall values for modified asphalt are better than the original asphalt, this indicates greater stability and resistance to rattan as well as higher resistance to acid rain.
