DURABILITY ANALYSIS OF POROUS ASPHALT WITH ADDITION OF RECYCLED ASPHALT PAVEMENT

Abstract

Transportation infrastructure plays a crucial part in the everyday life of social beings. For its design, highway agencies focus on acceptable and cost-effective design technique. For this goal, engineers are experimenting with porous pavements, and via accommodation of Recycled Asphalt Pavements the infrastructural wastes can be decreased. The usage of RAP will not only limit the consumption of our natural resources but also help in repurposing the waste materials for a beneficial purpose, meeting economic and environmental friendly needs of a country. Pavements over time becomes damaged by rutting, fatigue, Durability Analysis render it unfit for automobiles. Therefore, it is required to have such design which are cost effective and environment friendly. The usage of Recycled Asphalt Pavement acts as a significant component in reaching national prosperity. This project is based on analysing the performance of Porous Asphalt by employing varying quantities of Recycled Asphalt Pavement as an additive in Asphalt Concrete. NHA grade B, PARCO grade 60/70 Bitumen and RAP from the G-13 Reconstruction Project were employed in this investigation. On virgin bitumen, penetration, ductility, and temperature tests were performed. The RAP contents used were 10%, 20%, and.30%. After determining the OBC, volumetric, stability, and flow of AC mixes, performance testing was performed. Using those OBC and adding RAP as an addition in bitumen, several samples were made and tested for evaluation, and the results were compared to the performance testing results of AC mixes without RAP. Analyze Durability Porous Asphalt Pavement is tested to see how its durability compares to Porous Asphalt.
