MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611114799 A) filed by Chandigarh University on September 25, 2026, for Thermally Activated Self-Healing Retroreflective Thermoplastic Road Marking.
Inventor includes Pratham Saxena.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Thermally Activated Self-Healing Retroreflective Thermoplastic Road Marking relates to a thermoplastic road-marking layer (102) provided on a road surface (101), with distributed microcapsules (103) and retroreflective glass beads (107). Each microcapsule (103) has a polymeric outer shell (104) enclosing separated reactive agents comprising an isocyanate (105) and a polyol (106). Vehicle tire movement generates localized frictional heat that weakens and ruptures the shell (104), releasing the reactive agents which react to form a polymeric binding material (108). The binding material fills micro cracks in the thermoplastic road-marking layer (102) and re- bonds loose or partially detached retroreflective glass beads (107), thereby restoring surface integrity and supporting continued retro reflectivity. The mechanism is material-based and self-regulated by traffic-induced frictional heating without sensors, controllers or software. The arrangement is suitable for thermoplastic traffic markings requiring recurring resistance to surface damage and bead loss.
