Experimental study on the suitability of using polyvinyl chloride (PVC) plastics wastes in the production of Bitumnious mix for pavements Construction.

Abstract

This research assesses the use of ABS waste plastic in production of bituminous mix for flexible pavement. In particular, the research focused first in determination of the softening temperature of ABS waste plastics and characterizing aggregates bitumen and binder according to their physical properties. Furthermore, the bituminous mix containing ABS plastic waste was prepared using the Marshall Mix design and analysis for its Marshall properties was done and finally some Marshall specimens were prepared and tested to evaluate their indirect tensile strength as a measure of Optimum performance of the mix and durability. Summarily, the results of bituminous mix having ABS plastics showed better pavement performance results in terms of ITS than the conventional mix. The better results therefore mean better performing, durable, economically cheap and environmentally friendly road pavements can be constructed when ABS is used as a bituminous mix.
