PWD Trials Advanced Road Technologies to Boost Durability and Reduce Repairs.
Shimla:
The Public Works Department (PWD) is taking a major step towards improving road durability and minimizing maintenance costs by introducing two advanced road construction technologies. Public Works Minister Vikramaditya Singh announced today that Cement Grouted Bituminous Macadam (CGBM) and Stabilized Base Layer Technology have been selected for trial on the Shoghi–Mehli Road, one of the State’s frequently damaged road stretches.
Speaking at a press briefing, the Minister highlighted that PWD is responsible for maintaining nearly 35,000 km of roads across the State and is constantly exploring innovative methods to enhance road quality and ensure safe, all-weather connectivity.
“Due to harsh weather conditions, water-logging, and weak ground foundations, nearly 20 percent of our road network suffers repeated damage, leading to frequent repairs and high maintenance costs. These new technologies are being introduced as long-term solutions to improve road longevity and performance,” he said.
After consultations with the Central Road Research Institute (CRRI), a pilot project using CGBM and Stabilized Base Layer Technology is now underway on damaged sections of the Shoghi–Mehli Road. According to the Minister, these methods are expected to strengthen roads, improve their ability to handle heavy traffic, and increase resistance to water damage, significantly reducing the need for repeated repairs.
“The implementation of these technologies could extend the lifespan of roads up to 10 years, while lowering maintenance costs and providing a smoother and safer driving experience for commuters,” he added.
Minister Singh also noted that these technologies have been successfully employed in several States under the Pradhan Mantri Gram Sadak Yojana (PMGSY) and by the National Highways Authority of India (NHAI).
During the briefing, a presentation was made detailing the new technologies and the progress of work on Shoghi–Mehli Road. The Minister further announced the formation of a committee to identify additional road stretches where these technologies could be applied under the Annual Maintenance Plan for 2026–27.
