REJUBIT: A Bituminous Rejuvenating Agent and a Process for Recycling of Bituminous Pavements

• Saving of ~ ₹9.17 lakh/km (~ ₹ 9 Cr saved per 100 km) when roads are recycled using REJUBIT instead of repaving using new/fresh materials and imported rejuvenators.

• Significant Cost Savings: At Rs. 180/kg, REJUBIT provides a cost reduction of ~74% compared to imported rejuvenators. Enhances aged bitumen properties effectively, ensuring longer pavement life.

• Reducing Carbon Footprint: Use of REJUBIT reduces the carbon footprints involved in Road developments.

Recycling of bituminous roads offers a sustainable solution for road construction. To recycle a pavement; a chemical agent called rejuvenator is required to be added in to the old pavement material (RAP) which can reverse the stiffness happened in the bitumen due to oxidative aging. The rejuvenator collaboratively developed by CRRI and OOMS is rich in resins and is able to restore the physical and chemical properties of aged bitumen. This technology can address the future challenges of depleting raw materials , it reduces costs, minimizes resource consumption.

• REJUBIT enables cost-effective and sustainable reuse of old pavements (RAP) leading to superior performance, reducing import reliance and promoting Make in India.
• It reduces the carbon footprints involved in Road developments and enhances the recycling potential of aged bitumen, minimizing waste generation.
• By recycling and reusing existing pavement layers, REJUBIT helps avoid the problem of rising road levels in resurfacing projects.
