Border Road Organization (BRO) to build first steel slag road in which state?
A)
Uttarakhand
B)
Arunachal Pradesh
C)
Himachal Pradesh
D)
Uttar Pradesh

Correct Answer : Option (B) - Arunachal Pradesh


In a first, the Border Road Organization (BRO) will take up the construction of a pilot road stretch in Arunachal Pradesh using steel slag, which can withstand heavy rains and adverse climatic conditions. If it’s found successful, this can become a big solution for building durable roads along the strategic areas.
 
The project has been initiated after the success of using 100% steel slag on a port connectivity road in Gujarat, which has longer life and built at low cost. This 1.2 km Hazira port connectivity stretch was a research and development (R&D) project carried out by CSIR-CRRI in collaboration with a major steel manufacturer and steel ministry. 
 
The project was developed with the aim to “convert waste to wealth” and around one lakh tonne of processed steel slag aggregates have been utilized here substituting the natural aggregates, said director of CSIR-CRRI, Dr Ranjana Aggarwal.
 
The project has entered the India Book of Records and Asia Book of Records.
 
The National Highways Authority India (NHAI) will also use the steel slag for construction of a portion on Mumbai-Goa highway and the Indian Railways has also sanctioned a major R&D project to CSIR-CRRI to explore possible utilization of steel slag aggregate as railway ballast for track construction and maintenance.
 
India is the world’s second largest steel producing country and annually around 195 lakh tonnes of steel slag is generated and this quantity is slated to increase to 600 lakh tonne by 2030..
