Steel slag road technology from CSIR-Central Road Research InstituteSteel Slag Road technology paves the way for the sustainable and eco-friendly utilisation of 19 million tonne of waste steel slag generated annually in India as solid waste from various steel plants. CSIR-CRRI has pioneered the development of steel slag road technology by constructing the world's first steel slag road in Surat, using processed electric arc furnace steel slag aggregates. These aggregates are produced at Arcelor Mittal Nippon Steel’s Hazira plant under CSIR-CRRI’s technological guidance, through the valorisation of waste steel slag as processed steel slag aggregates. Approximately one lakh tonne of processed steel slag aggregates have been utilised as a 100 per cent substitute for natural aggregates in the construction of this six-lane bituminous steel slag road, including the road median and shoulders. Steel slag roads can be constructed with two-thirds the thickness of conventional roads using natural aggregates under identical design traffic conditions, resulting in a cost savings of 30 to 40 per cent. These steel slag roads can withstand heavy traffic and adverse weather conditions due to their high structural stiffness. They remain pothole-free and do not require structural rehabilitation for an extended period. Approximately 95 per cent of the road volume is built using processed steel slag aggregates, which are around 50 to 60 per cent cheaper than natural aggregates.REJUPAVE from Verma Industries and CSIR-CRRIDeveloped jointly by CSIR-Central Road Research Institute and Verma Industries, REJUPAVE (rejuvenator for bituminous pavement recycling) is an innovative product revolutionising road construction and maintenance in India by effectively recycling distressed bituminous layers in a road structure. In India, where most roads are bituminous pavements, regular resurfacing every three to four years is essential to maintain quality. Traditionally, this involved overlaying distressed pavements with fresh bitumen and aggregates, significantly increasing pavement thickness. In place of this practice, distressed bituminous layers can be milled and reutilised through indigenously developed technology REJUPAVE using a hot recycling process. This can not only lower the cost of maintenance but also conserve the bituminous binder. REJUPAVE employs a bio-oil-based rejuvenator that allows for the hot recycling of up to 70 per cent of reclaimed asphalt pavement material (RAP) in a new bituminous mix for binder and wearing course layers.REJUPAVE utilises a bio-oil-based rejuvenator made from plant-based raw materials, emphasising sustainability, and minimising environmental impact. Its ability to restore the viscoelastic and rheological properties of oxidised bitumen binders enhances pavement performance and longevity, contributing to more durable and resilient road infrastructure.

Implementation Status of Jal Jeevan Mission

Since August 2019 the Government has implemented Jal Jeevan Mission to provide assured potable water through household tap connections in rural India. At the start of the mission only 32.3 million (mn) rural households, representing 16.7 per cent, were reported to have tap water connections. States and union territories have reported that 125.8 mn additional rural households have since been provided with tap connections. As a result, of about 193.6 mn rural households roughly 158.2 mn, or 81.71 per cent, are reported to have tap water supply at home.\n\nThe State, district and village level st..

Jal Jeevan Mission Reaches Eighty One Per Cent Rural Coverage

The Government reported substantial progress under the Jal Jeevan Mission, launched in August 2019 to provide tap water to every rural household. At launch only 32.3 million (mn) rural households had tap connections and states and Union territories reported provision of 125.8 mn additional households by March 2026. Consequently, out of about 193.6 mn rural households around 158.2 mn, or 81.71 per cent, are reported to have tap water at home. The Finance Minister announced extension of the mission until 2028 in the 2025-26 budget speech. The Swachh Bharat Mission Grameen, launched in October 20..

Empowering Local Governance for Sustainable Rural Water Supply

The Ministry of Jal Shakti has aligned the Jal Jeevan Mission (JJM) with the 73rd Amendment to strengthen village level planning and community ownership of water supply. Gram Panchayats, village water and sanitation committees and Pani Samitis are to plan, implement, manage and maintain piped water systems, with gram sabha processes formalising handover and oversight. Implementation support agencies including non government organisations, community based organisations and self help groups have been empanelled to train local committees and promote women participation. Under JJM, the department ..
