India has more than 95% of the roads with flexible pavements. Regular maintenance is needed as these roads can develop cracks over time due to traffic and weather. People in the industry always look for new and better ways to make these roads durable. Using Reclaimed Asphalt Pavement (RAP) in flexible pavements is thus a solution. Reclaimed Asphalt Pavement (RAP) is a waste material produced during the reconstruction and rehabilitation of old pavements and provides a practical solution to reduce the need for virgin aggregate and binder. However, due to the poor cracking performance of aged binders, the use of RAP in road pavements is limited. Using high percentages of RAP in hot mix asphalt (HMA) can lead to early pavement distress. This can be solved by rejuvenating the aged bitumen in RAP. Rejuvenators are additives or agents that are added to the bituminous mix to restore or enhance the properties of aged or recycled bitumen materials. Before the application, it is important to evaluate the performance of hot bituminous mixes prepared with high RAP contents. The usage of RAP in the pavement would reduce the usage of fresh aggregates and virgin binders, thus conserving natural resources. The study adopts waste engine oil (WEO) and waste transformer oil (WTO) as rejuvenators. The study aims to find the optimum binder content from conventional mixes. The study also evaluates the effect of rejuvenators and RAP contents on the volumetric properties of bituminous mixes. The study also aims to identify the type and optimum dosage of each rejuvenator required to improve the properties of the bituminous mixes and to obtain the optimum percentage of RAP to be used.
