EFFECT OF MEDICAL WASTE PLASTIC ON THE TECHNICAL CHARACTERISTIES OF BITUMEN

Abstract

Various kinds of additives are known to impove the properties of bitumen in special road pavement applications such us waste plastic or rubber. In this paper, the effects of medical waste polypropylene (PP) content (3%, 6%, 9% and 12%)  on the technical characteristics of the bitumen has been investigate. Mechanical properties and differential thermal analysis (DTA) of the PP waste polymer were determined. Basic penetration, softening point, elastic recovery test was performed and study finding shows that penetration decrease while softening point and elastic recovery increase by addition of PP in the bitumen.
