Abstract: Coal-based thermal power plants all over the world face serious problems of handling and disposal of the ash produced. The high ash content (30–50%) of the coal in India makes this problem complex. At present, about 145 thermal power stations in India produce nearly 184 million(quantity) tonnes of coal ash per annum (CEA,2015).… View More

Abstract: More than 95 % of road network in India is made up of flexible pavement, especially due to the relative lesser initial cost, ease of construction and maintenance. The design of flexible pavement in India is done with criteria of load associated fatigue cracking and permanent deformation (rutting).… View More

Abstract: The flexible pavement is the most sought pavement in many countries like U.S, India etc mainly because of ease and low initial cost of construction and maintenance as compared to a concrete pavement. Due to the distresses caused in flexible pavements, it requires routine and periodic maintenance and strengthening in the form of added thickness.… View More

Abstract: With the current growth of infrastructure in India, traffic growth is very high, especially transportation of goods and services have also increased considerably in many fold and so the commercial vehicles. The current flexible pavement structure has been designed with a standard axle load of 80 kN and a tyre pressure of 560 kPA, as per Indian Road Congress-37, but numerous field studies conducted by CSIR-CRRI have shown that the trucks with standard and higher axles were found to be carrying more load than designated for them.… View More
