MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202611021496 A) filed by Bhawna Gundal; Dr. R. S. Kesharwani; and Dr. Sudesh Kumari, Rohtak, Haryana, on Feb. 23, for 'an integrated sustainable pavement construction system using recycled waste materials with age-hardening characterisation and life-cycle performance optimization.'
Inventor(s) include Bhawna Gundal; Dr. R. S. Kesharwani; and Dr. Sudesh Kumari.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a sustainable pavement construction system incorporating recycled waste materials into flexible pavement structures to enhance structural performance, durability, and environmental sustainability. The system comprises modification of bituminous binder using processed plastic waste and crumb rubber, incorporation of recycled aggregates including construction and demolition waste, recycled asphalt pavement, fly ash, and steel slag in base and sub-base layers, and rheological characterization of the modified binder using stiffness and phase angle parameters. Age-hardening behaviour is evaluated through spectroscopic oxidation analysis to predict long-term durability. The invention further integrates moisture-dependent subgrade modulus modelling for accurate structural response estimation and a life-cycle assessment and costing framework to evaluate environmental and economic feasibility. The integrated methodology reduces dependence on virgin materials, minimizes waste disposal burden, improves rutting and fatigue resistance, and extends pavement service life, thereby providing an optimized and eco-friendly pavement infrastructure solution."
