Ethylene Propylene Diene Monomer (EPDM) Effect on Asphalt Performance

The asphalt industry is increasingly developing with greater focus on sustainability. This study focuses the benefits of a binder modification stone mastic (SMA) by adding rubber—ethylene propylene diene monomer (EPDM)—into class 320 bitumen. observes advantages that occur for rutting and fatigue performance samples. was made incorporating 0, 2, 4 6% weight into each sample. tests performed samples were wheel-tracking test four-point beam bending test. results revealed varied outcomes, showing sample having highest initial stiffness modulus elasticity but lowest cycle to failure. Therefore, best performer determined as 4% sample, which consistently throughout, cumulative dissipated energy second-highest flexural stiffness, failure results. There clear indication test, rut depth, although there signs further improvement be achieved within 4–6% range. In addition, drain-off conducted mixtures, addition EPDM significantly reduced SMA values. Overall, improvements through an mix concerning resistance came from incorporation.
