Abstract
L'invention concerne un chauffage de chaussée (20) de pont utilisant des électrodes (24, 26) intégrées dans du béton conducteur et connectées à une source d'alimentation afin d'éliminer la glace et la neige de la chaussée. Un mélange à base de ciment contenant des quantités optimales de matériaux conducteurs est moulée dans des dalles (22) de béton placées sur la surface revêtue de la chaussée d'un pont. Dans une variante, des électrodes sont intégrées dans le béton conducteur. L'unité de contrôle pourvue de capteurs de température et d'humidité peut être couplée au chauffage de chaussée de pont.
