In this research study, permanent deformation of pure and zycotherm modified binders were evaluated. Conventional test results showed that all percentages of zycotherm reduce susceptibility of binders to temperature. G(*)/sin values of dynamic shear rheometer revealed that addition of zycotherm improves performance of binders against permanent deformation. Likewise, results of multistress creep recovery test indicated that zycotherm decreased the nonrecoverable compliance (Jnr) values, which is an indication of lower susceptibility of asphalt binders against rutting distress. According to test results, 0.1% of zycotherm is proposed to have the highest impact on performance of AC 85/100 asphalt binders against permanent deformation.
