MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051611 A) filed by Mr. B. Sravan Kumar; Mr. Pathlavath Tarun Naik; Mr. Katroju Vivek; Mr. Katuri Varun; and Ms. Shaik Karishma, Hyderabad, Telangana, on April 22, for 'a method for enhancing road durability using plastic waste modified bitumen for sustainable pavement construction.'
Inventor(s) include Mr. B. Sravan Kumar; Mr. Pathlavath Tarun Naik; Mr. Katroju Vivek; Mr. Katuri Varun; and Ms. Shaik Karishma.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a sustainable method for enhancing road construction by incorporating waste plastic into bituminous pavement. The invention provides a process for collecting, segregating, cleaning, and shredding waste plastic materials such as polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP), followed by their controlled incorporation into heated bitumen or coating over aggregates. The plastic is added in a proportion ranging from 8% to 15% by weight of bitumen, preferably around 15%, to form a plastic-modified binder. The modified bituminous mix is prepared using standard hot mix techniques and is subsequently laid and compacted to form flexible pavement. The incorporation of plastic enhances the binding properties, increases softening point, reduces penetration value, and improves resistance to water damage, rutting, and cracking. The resulting pavement exhibits higher durability, improved load-bearing capacity, and extended service life compared to conventional roads. The invention also provides an eco-friendly solution for plastic waste management by reducing landfill burden and environmental pollution. Additionally, it reduces the consumption of conventional bitumen, leading to cost-effective road construction. Thus, the proposed method offers a sustainable, economical, and high-performance alternative for modern infrastructure development."
