Abstract

Waste Polyvinyl Chloride (PVC) pipes from sewerage system, bottles, credit cards etc. is a non-biodegradable material and adds to the quantity of solid wastes on annual basis. This study aims at its useful deployment as an additive to the bitumen which is used to construct pavements. Waste PVC pipes when used as a modifier in bituminous mixtures, satisfied the requirements as per the standards as indicated by the results. The properties of bitumen mixed with PVC were studied and compared with those of the ordinary bitumen. The performance characteristics of the the conventional and modified bituminous mixes were investigated and comparative study was carried out. It was shown by the results that waste PVC has got no issue when utilized in road construction. Flow and Stability of the mix was found to be within the acceptable limits after the PVC waste pipes have been incorporated. On the basis of experimental work it is concluded that the asphalt mixtures with waste PVC modifier can be used up conveniently in the construction of flexible pavement in hotter regions regarding their stability and flow characteristics.
