The rapid increase in the use of plastic materials in the recent years led to thernaccumulation of extreme amounts of plastic waste. Thermoplastics such as PET,rnPE, PP, PS and PVC as well as materials that derived from these are the type ofrnplastic most used and consequently create environmental problems. rnLandfill, incineration and recycling remains the primary options for solid wasternmanagement. One critical determinant of the acceptability of these options is therndifferent health risks associated with each. rnThe plastic waste that burnt and dumped in landfill sites can be recycled andrnused for different purpose. This includes the use of waste plastic in constructionrnof asphalt road. By recycling waste plastic, it is possible to protect thernenvironment from contamination. rnUsing waste plastic in asphalt road construction as an aggregate binder is one ofrnthe recent plastic waste approach. This will help us to avoid the environmentalrnpollution from open-air burning and landfill of plastic waste. rnIn this research the applicability of the waste plastic as a binder, together withrnBitumen has investigated, for this purpose, the plastic (Polyethylene rnterephthalate ) and bitumen mix was checked for certain quality that needed to rnbe a good binder. The natural bitumen had modified by adding PolyethylenernTerephthalate (PET) in different percentage by weight of bitumen. The tests thatrnconducted on the modified bitumen quality are Ductility, Penetration, andrnSoftening point of the plastic modified bitumen mix. Also the load bearingrncapacity of the modified bitumen asphalt (aggregate with modified bitumen mix),rnhad been tested. rnThe research had conducted the two methods of asphalt road making usingrnplastic waste. rnAfter doing the quality test, the research identified what percentage by weight ofrnplastic that should be mixed with bitumen to give a good quality of modifiedrnbitumen, accordingly 8% by weight in wet process and around 16% by weight ofrnPolyethylene Terephthalate(PET) in dry process were able to give good bindingrnproperty. This can enable us to recycle around 52.4 tons of PET waste (perrnkilometer of road) that would have gone to landfill and/or to open air burning andrnIncineration.
