    Abstract

    This study is an aim to investigate experimentally the influence of waste plastic PET on design and properties of asphalt concrete (AC). Asphalt concrete modification with plastic as bitumen modifier improves temperature susceptibility. Present study was purposed to design asphalt concrete with plastic as modified bitumen. The objectives of this study were to design the AC with waste plastic bottle as bitumen modifier, to assess the AC properties modified with waste bottle plastic and compare it with unmodified AC. AC was modified with 6% plastic as bitumen modifier. Marshal properties, Indirect Tensile Strength test (ITS) and Unconfined Compressive Strength (UCS) have been carried out at different temperature at 20°, 40°, and 60°C. The Marshal Test results show that Optimum Bitumen Content (OBC) unmodified AC attained 6.08% and 6.01% for AC modified with plastic. Stability, flow, marshal quotient, VMA and FVMA of unmodified AC attained higher value than modified AC. And only air void of modified AC was higher than unmodified AC. Air void of AC modified plastic attained 1.9% higher than unmodified AC. The result of unconfined compressive strength (UCS) and indirect tensile strength test (ITS) of modified and unmodified AC reached the highest value at temperature of 20°C. Further the UCS and ITS values started to decrease with the increase of temperature. However modified AC was sensitive less towards temperature compared with unmodified AC because there was large amount of UCS and ITS decrease. Therefore, waste bottle plastic could be utilized as bitumen modifier of asphalt concrete in low temperature region.
