Low density polyethylene (LDPE) waste goes to landfill or incineration which causes environmental pollution problems. In this work low density polyethylene carry bags waste collected from supermarkets , cleaning and shredding then mixed with asphalt hot mix at 1500C in shiryanElshimal of Roads and Dams laboratory . The change in marshal stability , flow and voids due to addition of low density polyethylene carry bags waste (4% , 6% , 8% , 10% , 12% , 14% , 16% & 18% ) of the asphalt weight is measured . This study is used Microsoft Excel for drawing fitting carves to compare the result . The result isimprovement in properties of asphalt hot mix design especially when use 10% concentration low density polyethylene waste of the asphalt weight, consequently improvement in the environmental pollution by using in asphalt andincost by replacing asphalt in mixture.
