Stiffness modulus properties of hot mix asphalt containing waste engine oil
This study presents the effect of waste engine oil (WEO) on the mechanical properties of hot mix asphalt mixtures containing waste lubricating WEO. It was added into mixture at 0%, 3%, 5%, 7%, 10% and 15% by weight of binder. The mechanical properties of the mixes were evaluated by conducting indire...

| Summary: | This study presents the effect of waste engine oil (WEO) on the mechanical properties of hot mix asphalt mixtures containing waste lubricating WEO. It was added into mixture at 0%, 3%, 5%, 7%, 10% and 15% by weight of binder. The mechanical properties of the mixes were evaluated by conducting indirect tensile stiffness modulus (ITSM) at temperatures of 25°C and 40°C. The results indicated that modified mixes exhibited lower stiffness modulus with the increasing amount of WEO as well as testing temperature. The increasing amount of WEO was found to have a good linear correlation to the decreasing of stiffness modulus. The finding showed that the WEO has the significant role as a softening agent which affected the stiffness modulus even at low percentage |
