| Summary: | Plastic foam used as a heat insulation layer in the road base protects the road from frost damage. For some years now this insulation method has been practised in Scandinavia and in other countries with a cold climate. A concentrated description is given of some of the insulation properties and effects. Particular aspects dealt with are the frost resistance capacity of the road base, partial insulation and frost heaving, special transitions with purposely arranged openings between the foam boards, icing problems, and construction economy. Pour proteger les routes des dommages causes par le gel, on a employe des plastiques cellulaires for-mant une couche d'isolant thermique. On utilise dtja depuis uncertain nombre d'annks cette methode en Scandinavie et dans d'autres pays froids. On dtcrit de facon condensee certains des effets et pro-prietes d'isolation. On traite en particulier de certains aspects de la resistance au gel de la couche de base de la route, de I'isolation partielle, du soulkvement par le gel, des transitions crkees au moyen d'ouvertures entre les plaques de plastique cellulaire, des problkmes ocwionnes par la formation d'au-feis et des economies realisables dans la construction.
