The Technology Council of Scientific & Industrial Research Central Road Research Institute (CSIR-CRRI) in New Delhi has developed an eco-friendly MSS+ technology for the construction of green roads in Uttar Pradesh. The eco-friendly technology eliminates the need to heat aggregate and bitumen, enabling road construction in all weather conditions. The technology has demonstrated superior quality parameters compared to conventional hot-mix roads. The adoption of MSS+ technology under the Pradhan Mantri Gram Sadak Yojana (PMGSY) in Uttar Pradesh will pave the way for similar initiatives across the country. With incentive funds, 38 PMGSY roads are being constructed with
30mm thick MSS+ technology, with plans to expand adoption in future projects across the state. The Council of Scientific and Industrial Research – Central Road Research Institute (CSIR-CRRI) has introduced its innovative MSS+ technology for road construction in Uttar Pradesh (UP), marking a significant step toward sustainable and eco-friendly infrastructure development. This technology promises to reduce construction costs, enhance road durability, and minimize environmental impact, aligning with India’s broader green infrastructure goals. MSS+ (Modified Structural Strength Plus) is a road construction technique that utilizes advanced material engineering to create stronger, longer-lasting pavements. (Road Engineering)
The technology involves the use of modified bituminous mixes combined with sustainable materials such as recycled aggregates, industrial waste by-products, and locally available resources. Uttar Pradesh has one of the largest road networks in India, and its rapid urbanization demands durable and cost-effective infrastructure solutions. Traditional construction methods often face challenges like premature wear, cracking, and potholes due to heavy traffic loads and extreme weather conditions. One of the key drivers for adopting MSS+ is its environmental advantage. The use of recycled aggregates and waste materials like fly ash from thermal power plants not only reduces landfill burden but also conserves natural stone and sand resources.
Additionally, the production process is designed to lower carbon emissions by reducing the amount of heat energy required in mixing operations. These measures support India’s commitment to the United Nations Sustainable Development Goals for climate action and responsible consumption. MSS+ offers significant cost savings by reducing the need for frequent repairs and by making use of locally sourced materials. The technology also shortens construction time, which is particularly important for minimizing traffic disruptions in busy urban areas.
Technology Transfer and Skill Development
The introduction of MSS+ in UP is accompanied by capacity-building programs. CSIR-CRRI is training engineers, contractors, and field workers on the best practices for implementing the technology. This not only ensures quality control but also creates new skill sets within the state’s construction workforce. To ensure the effectiveness of MSS+, roads built with this technology will be monitored over time for performance indicators such as surface condition, load capacity, and resistance to weather-related damage. Advanced testing tools and on-site inspections will help maintain quality standards.
The adoption of MSS+ aligns with national missions like the Pradhan Mantri Gram Sadak Yojana (PMGSY) for rural connectivity and the National Green Highways Mission under the Ministry of Road Transport and Highways. It also supports Uttar Pradesh’s vision of becoming a model state for sustainable infrastructure. If successful in UP, MSS+ could be scaled to other states facing similar road durability challenges. The technology’s adaptability to different climatic and traffic conditions makes it a promising candidate for nationwide adoption. With India’s ambitious infrastructure expansion plans, innovative solutions like MSS+ can play a crucial role in building roads that are not only stronger and more cost-effective but also environmentally responsible.
