Establishment of Road Drainage
The primary purpose of a road drainage system is to remove the water from the road and its surroundings. The road drainage system consists of two parts: dewatering and drainage. … “Runoff” covers the water flowing from the surface of the pavement via road shoulders and inner slopes to the ditches.
Methods of Road drainage networks
The first method – the combined sewage system, in which the drainage is carried out on the sewage network in case of little rain and is disposed of through purification plants.
The second method – A subsurface drain may comprise of aperforated pipe, a porous concrete pipe or solid pipe laid with open joints. Alternatively, a trench filled with a free draining material may be used to serve the purpose of a drain.
