Roadway water management : technical guide = Assainissement routier : guide technique

Road construction hydrology covers the re-establishment of natural flows, the drainage of roadways, drainage and the control of road pollution. The recommendation on road improvements of 1982 dealt essentially with the first two fields. The collection of guides "Water and road construction" deals with the protection of water resources and aquatic environments in the context of road infrastructure. A working group made up of hydraulic experts was set up by Sétra to collect up-to-date knowledge in the field of hydrology and take account of environmental protection-related impacts. This work took shape in a guide in three main sections : • the technical design of structures; • studies; • the quality procedure. General technical appendices give calculation examples and ABAC calculation charts to be used. It was devised to meet the needs and expectations of prime contractors. Its primary purpose is as a tool that assists in the design of drainage structures for new road projects and improvement planning studies on existing roads.
