Abstract:	The global construction industry is increasingly pivoting toward "Circular Construction" to mitigate the environmental impact of both plastic pollution and natural aggregate depletion. Plastic polymers, due to their low thermal conductivity, high toughness, and non—biodegradable nature, offer a dual—pathway for material enhancement: aggregate replacement (volumetric substitution) and micro—arming(structural reinforcement). This abstract explores the mechanical, thermal, and durability implications of integrating various plastic waste streams into concrete and asphalt systems. The construction industry is currently transitioning toward a circular economymodel to address the dual crises of plastic pollution and the depletion of natural mineral resources. The "Synergistic Integration"approach moves beyond simple waste disposal, treating plastic as a sophisticated additive that modifies the internal architecture of construction materials. By simultaneously utilizing plastic as Volumetric Aggregate Replacement and Fibrous Micro—arming, engineers can create "hybrid" matrices in both concrete (cementitious) and asphalt (bituminous) systems that outperform traditional materials in specific durability and insulation metrics. The transition from treating plastic as a "contaminant" to a "performance—enhancing additive" is the cornerstone of modern sustainable engineering. Through the combined application of aggregate substitution and micro—fibrearming, the construction sector can deliver high—performance, disaster—resilient infrastructure while effectively managing global plastic waste streams.
