CSIR-CRRI's MSS+ Tech Builds Green Roads in Uttar Pradesh

CSIR-CRRI’s eco-friendly MSS+ technology is transforming road construction in Uttar Pradesh by enabling green roads under PMGSY, reducing carbon emissions, and improving road quality with all-weather, energy-efficient processes.

Highlights:

• MSS+ tech used by UPRRDA to build 202 km of green roads in 2025.
• Eliminates heating of aggregate and bitumen; allows all-weather construction.
• Roads show higher quality than conventional hot mix roads.
• Reduces carbon emissions, supporting UN Sustainable Development Goals (SDGs).
• Technology developed in 2021 by CSIR-CRRI with JMVD Industries; proven successful since 2022.
• Inspected and praised by Dr. N. Kaliselvi, Secretary DSIR & Director General, CSIR.

The Council of Scientific and Industrial Research-Central Road Research Institute (CSIR-CRRI), New Delhi, has developed an innovative and eco-friendly road construction technology called MSS+. This technology is being implemented by the Uttar Pradesh Rural Road Development Authority (UPRRDA) to construct green roads under the Pradhan Mantri Gram Sadak Yojana (PMGSY). In 2025 alone, around 202 km of roads are planned to be built using MSS+ in Uttar Pradesh.

Unlike conventional hot mix methods, MSS+ eliminates the need to heat aggregates and bitumen, allowing construction in all weather conditions while significantly reducing energy consumption. Dr. Manoranjan Parida, Director of CSIR-CRRI, stated that roads made with MSS+ demonstrate superior quality compared to traditional methods.

During a project inspection from Mankapur–Nawabganj Road to Buxara via Amberpur in Gonda district, Dr. N. Kaliselvi, Secretary of the Department of Scientific and Industrial Research (DSIR) and Director General of CSIR, praised the road’s quality and emphasized MSS+ technology’s role in reducing carbon emissions, making it a vital step towards green infrastructure aligned with the United Nations Sustainable Development Goals (SDGs).

Chief Engineer Brajesh Kumar Dubey informed that 38 PMGSY roads totaling 202 km are currently being constructed with 30 mm thick MSS+ layers. Plans are in progress to expand the technology’s adoption statewide.

Developed in 2021 by CSIR-CRRI in collaboration with JMVD Industries, MSS+ has shown exceptional performance since its first deployment near Lucknow in 2022. Today, the technology is being used in six districts, heralding a new era of sustainable and efficient road construction in India.
