SPR-4834: Riprap and Aggregate Polyurethane Stabilization for Drainage, Erosion Control and Road

This study presents a comprehensive investigation of polyurethane-bonded aggregate layers for drainage and erosion control applications in two phases. In Phase 1, laboratory tasks include identifying suitable aggregate sources, characterizing physical properties, optimizing mix proportions and mixing methods, and conducting comprehensive laboratory testing. Phase 2 focuses on site selection, construction, and in-situ performance monitoring. The study aims to optimize design parameters, assess environmental impact, and provide guidelines for successful implementation of polyurethanebonded aggregate technology.
