Abstract

In petrochemical industry, the production of polyvinyl chloride (PVC) is accompanied by formation of heavy end WASTEs which consist of a mixture of di and multichloro compounds as kind of materials which are generated in ethylene dichloride (EDC) purification. A high quantity of chloro compounds found in the heavy end WASTE allows it to be polymerized with alkaline polysulfides to form POLYSULFIDE POLYMERs. Thus, according to this, the environmentally hazardous heavy ends WASTE can now be converted into useful POLYSULFIDE POLYMERs without any environmental problem. There are some methods for synthesizing a POLYSULFIDE POLYMER (PSP) from this WASTE. PSP with a rubbery property can be used for modification of bitumen. In this research the effects of POLYSULFIDE POLYMER (PSP) and the POLYSULFIDE POLYMER prepared by heavy end WASTE (wPSP) on bitumen and asphalt have been studied. Samples of 1, 3, 5% of PSP and wPSP as modifiers in bitumen have been prepared and their physical and mechanical properties are compared. Using this new modifier causes a fall in softening point (PSP=39.5%, wPSP=27.6%) and increase in penetration point (PSP=17.8%, wPSP=15.5%) and in asphalt mixture it causes decreases in rutting but has a small effect on MARSHALL STRENGTH of asphalt samples (PSP=4%, wPSP=11.6%).
