Title:

Information on the Planning, Construction and Operation of Chemical Thawing Agent Spraying Installations

Abstract:

Chemical thawing agent spraying systems are fixed equipment of the winter service. Road surface and weather condition detectors detect the ice formation of a road and trigger a thawing agent spraying system into operation. A spraying system allows the timely prevention of icing on hazardous places and assists a conventional (usually mechanical) winter service, by preventing the packing down of the snow layer. This paper covers application criteria, benefits and costs, the technical principles of installation, and operations.
