This problem troubles the people living in the old areas of the cities that whenever roads are built, they become higher and the drains and people’s houses become lower. Due to which there is problem of waterlogging during rainy season.read more

New Delhi. Now recycling of old roads will be easy and economical. Central Road Research Institute (CRRI) has invented Rejupave technology. With this technique, 5 to 10 cm above the road is used to repair old roads. A layer of tar is laid, due to which the road becomes higher. In this process, a large quantity of ballast and coal is required every year in the country. Excessive use of both natural resources has adverse effects on the environment.

Up to 60 percent of the material can be reused by uprooting the layer of coal tar with the Rejupave technology developed by CSIR, CRRI and Verma Industries. Apart from this the cost will also come down. CRRI used new technology to construct one km of National Highway in West Bengal. The road has been prepared. This is the first highway in the country where new technology has been used. 5000 to 6000 commercial vehicles pass through this road every day. The country’s reputed road construction companies Cube Highways, Marcoline, VR Techniques, Saras Infrastructure have been involved in the construction of this road.

Road material is recycled with the help of this plant.

Dr. Satish Pandey, chief scientist of CRRI, who developed this technology, says that till now 30 percent of the coal tar material in the country was reused, but with Rejupave technology, up to 60 percent of the material can be reused.

They say that the cost of a road built using this technology will be 40 percent less than the normal one. In this way money will be saved. Besides this, the greater the thickness, the stronger it will be. This technology also has other benefits. Completely Eco Friendly This technology is completely eco friendly. The technology is based on bio oil.

Helpful in preserving natural resources

Technology will be helpful in preserving natural resources. At present, coal tar is imported, but with this technology the use of coal tar can be reduced. In road construction, gravel is made by breaking stones, but with the help of technology, natural resources can be saved by reusing the material.

completely indian technology

This technology has been developed by CSIR-CRRI and Verma Industries which is completely Indian. This indigenous technology is also cheaper than imported technology.
