Jaipur, Nov 16 (UNI) Stressing the need for conservation of road raw materials like fertile soil, aggregates, sand and bitumen, Union Minister of State for Surface Transport K H Muniyappa asked engineers to explore possibilities of using industrial wastes like flying ash and slag in road construction.
Speaking at the inaugural session of the 68th Indian Road Congress here this evening, Mr Muniyappa said while there was a need to save scarce physical resources including our fertile soil, at the same time, there was a problem of storage of industrial wastes like flying ash and slag.
He suggested the engineers to explore the possibility of using stabilizer chemicals and modifiers for reducing thickness of different layers of roads.
He also asked them to learn from the fast paceed development of highway roads in China.
''Technocrats should really ponder over the exmaple of China, which did not have a single kilometer of highway in 1988, but now has a world class network of some 41,000 Kms of highways, second only to the United States in size.'' He said it was true that we in India were also doing well in road development but should not become complacent with our achievement.
''There is an urgent need to do a comparative study of road development in various countries such as China, US and so on'', the minister said.
