Özet
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 deformation. 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 conducted 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 demonstrated 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. © 2024, Kare Publishing.
