Design of Road Drainage System

Proper drainage system is one of the basic requirements of a road project. Poor drainage results into losses in the form of damaged roads and reduced serviceability. In spite of this, adequate priority for drainage system is rarely accorded. Funds required for a drainage system are small as compared to the enormous funds needed for development of road infrastructure and to meet the recurring losses due to poor drainage. It is necessary that due priority is given to the drainage of roads to ensure sustainability of road infrastructure. The road drainage issues which most of the cities in countries like India face today have been identified with the help of a study undertaken in Panipat city, an industrial city of Haryana, India. It also exhibits the urgent need for a rational and simple design of road drainage system. As the existing guidelines for the design of road drainage system have some shortcomings in respect of clarity on some of the design parameters and their complexity to use, the book brings forth the simplified design guidelines for the design of road side drainage system.
