Development of Porous Asphalt Pavement using Recycled Surface Dressed Pavement Materials (RSM)

Abstract

The study aims to create sustainable porous asphalt by integrating recycled surface-dressed pavement materials (RSM) instead of traditional dense asphalt mixes. Experiments show RSM meets eco-friendly pavement construction standards, with mixtures ranging from 0% to 80% RSM. Physical properties like Aggregate Impact Value (AIV), elongation, flakiness, 6water absorption, and specific gravity differ between virgin aggregates (VA) and RSM. Despite flow and stability issues, the Marshal quotient meets industry standards. Permeability studies reveal a link between RSM percentage and porous asphalt permeability, highlighting the need for material optimization. The research emphasizes the cost-effectiveness and performance of recycled materials in porous asphalt, offering a practical solution for managing runoff water and promoting sustainable infrastructure. Utilizing RSM in porous asphalt provides sustainability and cost benefits.
