Pavement Design in Road Construction BY Kiran Biradar Introduction Pavement design is the major component in the road construction Nearly one third or one half of the total cost of construction so careful consideration should be taken in design of pavementBecause of the complexity of the overall construction process we chose to observe report on analyze and model the paving process on the base layer of the 15 lane road At that time the other lane of the road was not paved yet The road has slightly increasing grade and curve along the process
