Study the Effect of Adding Plastic and Rubber Waste Mixture on the Physical and Chemical Properties of the Asphalt

Abstract

The use of industrial waste such as scrap rubber tires and plastics in the production of asphalt binders has become widespread due to economic and environmental benefits. In particular, the use of recycled waste plastic in asphalt binders and mixtures is gaining more attention. This presents work analyses and evaluation of rubber granules extracted from used tires, and plastic waste in asphalt modification. It focuses on the physical properties of modified asphalt compared to the conventional asphalt binder. The evaluated properties of asphalt binders were penetration value, storage stability and ductility test. Overall, the incorporation of combined polymer wastes into asphalt matrix can significantly improve physical properties of asphalt and has potential economic and environmental benefits. The performance of modified asphalt is highly dependent on multiple parameters, such as waste sources, mass of materials, and the blending conditions such as reaction temperature and mixing speed.
