**Policy Summary: Implementation of MSS Technology for Green Road Construction in Uttar Pradesh**
The Uttar Pradesh Rural Road Development Authority (UPRRDA) is utilizing an innovative MSS (likely stands for Mastic Stone Slurry) technology, developed by the Council of Scientific and Industrial Research-Central Road Research Institute (CSIR-CRRI), for the construction of green roads within the state under the Pradhan Mantri Gram Sadak Yojana (PMGSY). This eco-friendly technology eliminates the need for heating aggregate and bitumen, enabling road construction in all weather conditions and resulting in superior road quality compared to conventional hot mix methods.
In the current year (2025), approximately 202 kilometers of roads are planned for construction using MSS technology across 38 PMGSY road projects. A 30 mm thick layer of MSS is being applied to these roads, funded by incentive allocations from the Government of India. One such road, constructed along the Mankapur-Nawabganj Road to Baksra via Ambarpur in Gonda district, was recently inspected by Dr. N. Kalaiselvi, Secretary, Department of Scientific and Industrial Research, Government of India, and Director General, CSIR, who commended its quality and its potential to reduce carbon emissions, aligning with the United Nations Sustainable Development Goals (SDGs).
The MSS technology was developed by CSIR-CRRI in collaboration with J.M.V.D. Industries after two years of research, concluding in 2021. The first road using this technology in Uttar Pradesh was built near Lucknow in 2022. Currently, roads in six districts of the state are being constructed using this innovative method. Key personnel involved in the project include: Dr. Manoranjan Parida (Director, CSIR-CRRI and President, Indian Roads Congress), Mr. Satish Pandey (Senior Principal Scientist, CRRI, and inventor of MSS technology), Mr. Brijesh Kumar Dubey (Chief Engineer, UPRRDA), and Mr. Ravi Shankar Jaiswal (J.M.V.D Industries). Expansion of the technology's adoption in future projects across the state is planned.

CSIR-CRRI’s MSS+ Technology Paving the Way for
Green Road Construction in Uttar Pradesh
Posted On: 11 AUG 2025 1:45PM by PIB Delhi
The Council of Scientific & Industrial Research – Central Road Research Institute (CSIR-CRRI), New Delhi,
has developed an innovative MSS+ technology which is being utilized by the Uttar Pradesh Rural Road
Development Authority (UPRRDA) for the construction of green roads in the state. Using this eco-friendly
technology, approximately 202 kilometres of roads under the Pradhan Mantri Gram Sadak Yojana (PMGSY)
are planned for construction in Uttar Pradesh during the current year.
MSS+ technology eliminates the need to heat aggregate and bitumen, enabling road construction in all
weather conditions. Roads built with this technology have demonstrated superior quality parameters compared
to conventional hot mix roads, informed CSIR-CRRI Director and President of the Indian Roads Congress,
Dr. Manoranjan Parida.
As part of the project review, Secretary, Department of Scientific and Industrial Research, Government of
India, and Director General, CSIR, Dr. N. Kalaiselvi, inspected the road constructed with MSS+ technology
along the Mankapur–Nawabganj Road to Baksra via Ambarpur in Gonda district.She was accompanied by Dr. Manoranjan Parida; Senior Principal Scientist, CRRI, and inventor of MSS+
technology; Mr. Satish Pandey; Director, Central Building Research Institute;Dr. P. Pradeep Kumar; Director,
CSIR-SERC, Dr. N. Anandavalli, Head, CSIR Science Communication and Dissemination Division, Dr. G.
Mahesh; Chief Engineer, UPRRDA, Mr. Brijesh Kumar Dubey; State Technical Officer UPRRDA, Mr. D. D.
Pathak; officials from the Rural Engineering Department, Gonda; and technology provider Mr. Ravi Shankar
Jaiswal of M/s J.M.V.D Industries.
After the inspection, Dr. Kalaiselvi commended the road quality and highlighted that MSS+ technology
significantly reduces carbon emissions during road construction—making it a key enabler of green
infrastructure in alignment with the United Nations Sustainable Development Goals (SDGs). She noted that
the adoption of this technology under PMGSY in Uttar Pradesh will pave the way for similar initiatives across
the country.Chief Engineer, Mr. Brijesh Kumar Dubey, informed that with incentive funds allocated by the Government
of India, 38 PMGSY roads—covering a total length of 202 kilometers—are being constructed with 30 mm
thick MSS+ technology. He further stated that plans are underway to expand the adoption of the technology in
future projects across the state.
Senior Principal Scientist, Mr. Satish Pandey, explained that MSS+ technology was developed by CSIR-CRRI
in collaboration with J.M.V.D. Industries in 2021 after two years of intensive research. The first road using
this technique in Uttar Pradesh was built near Lucknow in 2022, and has performed exceptionally well over
the last three years. Currently, roads in six districts of the state are being constructed using this innovative
method.
