Abstract

Transportation contributes to the economic, industrial, social and cultural development of any country. Transportation is vital for the economic development of any region since every commodity produced whether it is food, clothing, industrial products or medicine needs transport at all stages from production to distribution. It provides movement of passengers and goods from one place to another place. Main modes of transportation in our country are Roadways. Railways, Waterways, and Airways. Out of these, roadways allow movement of about 85% of passengers and 70% of goods because it is nearest to the people and also provides flexibility for movement of vehicles.Pavements are generally classified into two categories based on the structural behaviour :Flexible Pavement and Rigid Pavement.
