MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202631123734 A) filed by C. V. Raman Global University on October 15, 2026, for Modular Prefabricated Bamboo-Reinforced Plastic Waste Bio-Concrete Road Panel With Self- Healing Capability.
Inventors include Abhijit Sahu; Ayush Kumar Gupta; Pritideepa Mohanty; and Dr. Debashish Dash.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a modular prefabricated road panel for durable rural and hilly road construction, particularly suited to the Northeastern states of India. The panel comprises a bamboo reinforcement mesh embedded within a concrete matrix, the matrix being modified with shredded LDPE and/or HDPE plastic waste to reduce water absorption, improve flexibility, and reduce brittle failure. A bio-concrete composition infused with Bacillus pasteurii bacteria is incorporated in the matrix so that, when moisture enters a micro-crack, the bacteria precipitate calcium carbonate by microbial induced calcite precipitation and autonomously seal the crack, enabling repeated self-healing. The panels are factory-cast in moulds, cured under controlled conditions, and provided with interlocking edges, an anti-slip surface texture, and drainage channels for quick installation. The composite structure provides enhanced tensile strength, water resistance, and structural lifespan compared with conventional cast-in-place concrete roads and with each constituent used individually. The invention converts bamboo and plastic waste into road infrastructure and allows individual damaged panels to be replaced.
