HEATED ROADS

UPPVAERMDA VAEGAR

An investigation is reported which will form the basis of a study of how heat flow in the road structure is affected by factors such as wind, precipitation, humidity surface moisture etc. The investigation, which was designed to find how the temperature in the road surface and inside the road structure (for a certain heat input and for given external climatic conditions, varies with the spacing of the heating loops and the depth at which they are laid, was performed in a low temperature laboratory in which a road structure was built to natural scale. Details of the investigation are briefly outlined. Part of the extensive body of data collected are summarized in diagrams. Data indicate that the loops should be laid relatively near the road surface. The significance of large heat storage in the road structure, and the influence of wind velocity are also discussed.
