Use of fly ash & other stabilizing agents for construction of cost effective roads in Sambalpur District of Orissa

Depending on the area, type of soil and type of fly ash, the optimum mix for soil stabilization varies considerably. As the roads of Western Orissa are in very poor condition and there are many big power plants coming upin these regions, fly ash utilization in road construction has good potential. Using locally available weak soil from Burla, fly ash from nearby Hindalco and locally available lime manufactured at Katni, various tests were carried out to determine the California Bearing Ratio (CBR) and other criteria like liquid limit, plastic limit, sieve analysis etc. The intention was to determine the mix giving the maximum CBR value and satisfying therequirement of the Indian Roads Congress. The maximum cost saving per km road built was achieved with a mixture of 70 parts soil + 30 parts fly ash+ 2 parts lime.
