Glass Grid Tech Tested to Prevent Cracks on Chennai-Bengaluru Highway

Speedy Summary

• The National Highways Authority of India (NHAI) is trialing a new “Glass Grid Rapid” technology on cracked portions of the NH-44 stretch between Walajah toll gate (Ranipet) and Krishnagiri, aimed at improving durability and safety.
• Glass bead layers, designed by IIT-Madras, consist of tiny particles laid on cracked areas like plaster. A fresh 40 mm layer of bitumen is added on top for reinforcement.
• Two trial sites have been identified: Eraivankadu village (1.2 km stretch),and Kannigapuram village (2 km stretch),with work nearing completion. Performance will be monitored for 1-2 years before further implementation on other highways.
• Benefits cited include better crack prevention to reduce potholes, waterlogging during monsoon, longer shelf life for bitumen stretches, reduced costs compared to traditional methods, and quicker repairs needing fewer labor resources.
• Additional upgrades underway include replacing damaged steel medians, road markings like pedestrian crossings, bush removal near medians, increasing retaining wall heights on elevated corridors from two feet to five feet for enhanced motorist safety.

Indian Opinion Analysis
The introduction of glass bead technology signifies an innovative move by NHAI to address recurring issues such as potholes and water damage affecting Indian road infrastructure-a persistent challenge particularly exacerbated during the monsoons. By proactively leveraging research-driven solutions developed in India (in this case by IIT-Madras), this pilot project showcases a commitment toward lasting highway maintenance practices that potentially lower costs while improving roadway lifespan.

Monitoring its long-term efficacy across various climate conditions could provide critical insights into broader adoption across India’s sprawling network. Moreover, efforts to enhance retaining walls along elevated corridors reflect NHAI’s emphasis not only on durability but also optimized safety measures for motorists-especially relevant given rising concerns over traffic-related accidents in India.

Such initiatives signal advancements towards better-maintained national highways wich are foundational for economic growth via improved connectivity; yet ensuring rigorous evaluation prior to scaling would remain essential for maximizing positive outcomes without unwarranted expenditure from public funds.
