The Maharashtra State Road Development Corporation (MSRDC) has sought technical guidance from the Indian Institute of Technology-Bombay (IIT-B) to repair cracks that have appeared on the Pune-Mumbai expressway due to wear and tear of the concrete panels on the road.

A team from IIT-B will soon conduct a survey of the 95-km expressway and suggest measures to repair the damage, an MSRDC official told TOI.

The survey will be completed in a week’s time, after which the IIT team will submit a report to the MSRDC.

MSRDC officials said each lane of the expressway has around 300 concrete panels per km. As the expressway has six lanes, three in each corridor, there are nearly 2,000 panels per km on the expressway. Cracks on the road surface have appeared because of wear and tear of the panels due to geographical and weather conditions and movement of vehicles, officials said.

The expressway was opened to traffic ten years ago. The cracks are not major in nature, but need to be repaired to prevent further deterioration. Not all panels need to be repaired, officials said.

Earlier this year, the MSRDC completed repairs of panels on a 20-km stretch of the expressway near Mumbai. The team will also study the effectiveness of these repairs. The MSRDC spent around Rs 1.5 crore for the repairs.
