Importance of road infrastructure is widely recognized as a potent means of socio-economic integration and is vital for the economic development of the country. During the past two decades, huge investments have gone into the road sector. In the last five years there has been a significant growth in the road network. Being ranked as the fourth largest economy in the world, infrastructure facility is yet to match with the world class standard because of inadequate serviceability standards and capacity constraints which are required to meet the ever increasing and continued transportation demand, specially by heavy commercial vehicles. The present situation is such that even the improved facilities created/being created at huge capital cost are still falling short of requirements and are severely overstressed. Consequently, some of the sections of the highways recently developed are deteriorating faster than expected and have started developing distresses/defects within two years after the road is open to traffic. The rate of pavement deterioration is rapid showing signs of premature distress/failure, especially in the form of severe rutting coupled with cracks and deformation/settlement etc. |
