After 2014, the speed of the construction of cement concrete road for national highways and expressways, in cities and even at village level has significantly increased due to the policy adopted by the Government of India. India has a road network of more than 5.6 million kilometre, comprising of a mix of modern and narrow national highways, besides expressways, state highways, project roads, urban roads, rural roads, including unpaved roads [https://en.wikipedia.org/wiki/Indian_road_network]. Figure 1 shows the length-wise percentage of different type of roads in India as on March 2016.
