A Study on Design and Execution of White Topping Road

India has a second largest road network after USA and it is still called as a developing country. The reason is the poor condition of roads. Most of our roads are bituminous type, which have short life because of failures in the form of fatigue cracking, rutting and early signs of distresses. These distresses get more pronounced in hot climatic regions like India as bitumen is highly sensitive to temperature. White topping is the solution to such problem. Concrete is known to be relatively stiffer material and less sensitive to high temperature which gives better performance against rutting and cracking and also in terms of rehabilitation and repair. White topping over the bituminous pavement provides better durability, strength and additional life of 20-30 years. The objective of the project is to investigate experimentally by following the properties of mix concrete with varying percentage of fly ash as per Indian Road Congress (IRC) guidelines
