N2 - This Sulfur extended Polyvinyl Acetate copolymers (SEPC) were prepared in a melt blender at 100 rpm for different blending times and temperatures, and mixed with asphalt cement in shear blender to improve its quality for road construction applications. The amounts of SEPC in asphalt cement vary according to the properties of asphalt used. SEPC was mixed with asphalt cement at 4-6% by weight. The SEPC modified asphalt binder was mixed with aggregate at different ratios to produce polymer modified asphalt concrete mix (PMACM). Marshall compaction procedure at 140°C was used to prepare PMACM. The resulted PMACM was studied by means of stability, stability loss, performance grade PG, rutting resistance and fatigue resistance. The results showed improvements in the properties. The results are comparable to those obtained for other commercial polymers. The presence of chemically bonded sulfur will reduce the amount of polymers to be used in asphalt modification and add value to elemental sulfur. The results obtained have appreciable cost effectiveness but there is need for further improvement in its performance.
