This study examines the role of fibers formed from para-aramid and micropolyethylene in enhancing the performance of stone mastic asphalt (SMA) mixtures against permanent defor- mation. The use of SMA mixtures has the potential to mitigate permanent deformation and plasticity. Marshall tests, static creep tests, fatigue tests, and wheel track tests were conduct- ed on samples prepared using the modified Marshall design method to achieve the research objectives. According to the test results, Samples containing 1.5% of the fiber mixture's total weight exhibited greater strength than other samples. Additionally, these samples demonstrat- ed the most minor displacement against rutting among all prepared samples. Based on these findings, incorporating fibers containing Para-aramid and Micro-polyolefin in SMA mixtures can enhance the performance of this type of mixture against permanent deformations.
