The Evaluation of Physical and Mechanical Properties of Synthetic Polymer Modified Hot and Warm Mix Asphalt

Abstract The application of polymer in an asphalt concrete (AC) mixture has reached wide popularity lately to deal with the increasing demand for higher quality roads heavier traffic loading. Ethylene-vinyl acetate (EVA), classified as a thermoplastic, is currently one most popular polymers employed. This research attempts evaluate effect adding EVA by means dry method, namely pouring additive directly into mixture, which produces both hot and warm Polymer-Modified Asphalt Concrete (PMAC) mix. FTIR result indicates thermoplastic material. Moreover, volumetric mechanical properties were examined through density semi-circular bending (SCB) tests. outcomes show that inclusion could slightly modify VMA AC Meanwhile, tensile strength, fracture energy, crack resistance index (CRI), flexibility (FI) results describe substantial enhancement brought polymer, generally trend up 200% control Conclusively, enhance physical mixes optimum dosages 5 6%. Additionally, PMA are somewhat comparable regular
