RHEOLOGICAL CHARACTERIZATION OF INDUSTRIAL WASTE MODIFIED BITUMEN

The aim of this research is to evaluate the rheological properties industrial waste modified bitumen. varying proportion polypropylene ranging from 0% 20% weight bitumen at 5% interval with 60/70 penetration grade was used. asphalt binder modification prepared by using high-speed mixer temperature 150 °C 190 °C. conventional test like softening point, penetration, ductility, flash and fire point were carried out assess physical characteristics unmodified bitumen, thereafter dynamic shear rheometer rotational viscosity conducted determine result indicated that has ability improve increased decrease point. Polypropylene provides better resistance against permanent deformation due their increase in complex modulus phase angle. It can be concluded could level performance service life road.
