DEICING SYSTEM ON THE BRIDGE OVER THE RIVER IJSSEL NEAR ARNHEM, NETHERLANDS

The Dutch company Nido Universal Machines B.V. produces and installs deicing systems. In the Netherlands, porous asphalt is often used on the construction of traffic lanes. Conversion of different types of asphalt should be avoided, due to the fact that porous asphalt is also used on bridges (concrete/steel or concrete). The Ministry of Transport selected Nido to construct and install five automatic deicing systems on steel bridges. The nozzles are activated successively in the direction opposite to the traffic flow, 30 cm. above the road surface.
