Modification of Asphalt Binder with Waste Expanded Polystyrene (EPS) Foam

Waste polymers are widely used in asphalt modification, especially, order to reduce their detrimental effect on the environment. This study discusses usability of waste expanded polystyrene (EPS) foam modification. In this respect, EPS foam, which produces both production and use stages, was mixed with bitumen by weight at ratios 2%, 4%, 6%, 8%, dry modification method employed. The penetration, ductility, softening point, flash specific gravity values virgin were compared modified bitumen. comparison made graphical statistical methods. A strong correlation between physical properties ratio observed. drop observed penetration ductility values. Besides, it found analyses that 2% increase additive is not sufficient make a significant difference bitumen, therefore, should be least 4%. Overall, concluded can for hot regions where low required.
