        abstract = {The rapid growth in traffic intensity, axle loads, and environmental variations has exposed the limitations of conventional bituminous pavements, particularly in terms of rutting, cracking, and temperature susceptibility. This study investigates the performance characteristics of polymer-modified bituminous concrete incorporating waste plastic through both dry and wet mixing processes. The primary objective is to enhance the mechanical properties of bituminous mixes while addressing environmental concerns associated with plastic waste disposal. In this investigation, plastic waste in the form of shredded carry bags was utilized as a modifier. In the dry process, plastic was blended with heated aggregates prior to binder addition, whereas in the wet process, plastic was incorporated directly into hot bitumen to form a modified binder. Standard laboratory tests were conducted on aggregates and binders in accordance with Bureau of Indian Standards (BIS) specifications to ensure material suitability. Marshall mix design was employed to determine the optimum binder content (OBC) for both conventional and modified mixes. Comparative analysis revealed that polymer-modified mixes exhibited improved stability, reduced flow values, and enhanced resistance to deformation compared to conventional bituminous concrete. The results indicate that plastic modification, particularly through the dry process, offers a cost-effective and sustainable approach for improving pavement performance.},
