Abstract
Abstract Utilization of by-product or waste materials in paving structure may provide environmental and economic advantages. Accordingly, in this experimental study, the waste polyethylene terephthalate (PET) polymers, shredded water bottles, was used in hot mix asphalt (HMA) preparation. The HMA’s mechanical properties were inspected by means of Marshall Stability, volumetric characteristics, Indirect Tensile Strength Test, and Tensile Strength Ratio. The laboratory test results revealed a significant enhancement in mechanical performance, especially in moisture damage resistance results.
