UTILIZATION OF RECLAIMED ASPHALT PAVEMENT (RAP) WITH PLASTIC WASTE (Dry Process) AS ROAD PAVEMENT MATERIAL IN FLEXIBLE PAVEMENT USING HOT MIX ASPHALT (H.M.A.) TECHNIQUE (Marshall Stability Method)

Abstract

The Reclaimed Asphalt Pavement Material (RAP) is obtained from the reclamation process from the bituminous roads, which are not commonly used for further construction, and dumped near the site. The RAP can be used as an aggregate. RAP also contains bitumen binder, which can be utilized in pavement construction. Since a decade plastic waste is used in road construction. Plastic waste safe disposal is also a big challenge to humans for protecting our environment and eco-system. There is no literature or research on the combined uses of RAP with Plastic waste. This project uses two waste materials, Reclaimed Asphalt Pavement Material (RAP) and Plastic waste for the construction of flexible pavement. Designing Dense Bituminous Macadam (DBM) Grading-II, which is now commonly used for flexible pavement on National Highway (NH), and State Highway (SH). Prepared samples with Reclaimed Asphalt Pavement material (RAP) and virgin aggregate, satisfying grading and specifications of aggregate as per MoRTH recommendations using Job mix formula (JMF). Bitumen Grade VG-30 used for binder. Adding Plastic waste as per IRC SP:98 2022[2] on hot aggregate (Dry Process) starting from 6% and increment of 2% up to 12% by weight of Optimum Bitumen Content (OBC). Assuming plastic will function as a binder. Comparing samples properties i.e., density, Marshall stability, flow value, air voids, voids in mineral aggregate, [VMA], and voids filled by bitumen [VFB]. From comparison found that RAP - 25% and Plastic waste 8% has satisfied all criteria of design & showed higher stability. The use of Reclaimed Asphalt Pavement Material (RAP) can save mines and disposal problems. Plastic waste uses in road construction also solves plenty of problems for the environment. The use of both waste materials can reduce the construction cost of the highway project. Key Words: Plastic waste, Marshall, stability, flow, energy, . environment ,Reclaimed Asphalt Pavement, RAP.
