Abstract

The provision of raw materials is a major challenge for the next generation due to the improvement of living standards and population growth, as well as the expansion of construction and industrial activities, causing unparalleled demands for raw material supplies. Plastic waste and spent lubricants are the most important polymer waste, with a share of 75.5% of the total available municipal waste. The Central Agency for Public Mobilization and Statistics confirmed that the largest solid waste sector is currently unused. The present study included modifying the rheological properties of bitumen by partial substation using solid waste materials represented by PVA and spent lubricating oils. The transformation process was carried out at a temperature of 180°C in the presence of sulfur again and anhydrous aluminum chloride. The rheological properties of the original and modified bitumen composites were investigated, which included measurement of penetration, softening point and ductility, as well as the calculation of the penetration index. The modified composites were cured with the original asphalt bitumen patches for 12 months, and then rheological properties were re-measured again after one year of aging. This is an actual case study of the replacement of bitumen with solid waste and the positive advantages over its physical properties
