A method for thawing frozen road culverts. The first step involves positioning an electrically conductive cable in a road culvert prior to an ice blockage occurring. A connection end of the electrically conductive cable is anchored in an accessible location. The second step involves connecting a power source to the connection end of the electrically conductive cable after an ice blockage of the road culvert has occurred and supplying power to the electrically conductive cable, such that energy generated by power flowing through the electrically conductive cable causes a flow path to be created through the ice blockage in the road culvert.

Méthode de dégivrage d'ouvrages de drainage de routes. La première étape consiste à installer un câble électrique dans un ouvrage de drainage avant que la glace ne cause de blocage. Une extrémité de connexion du câble électrique est fixée dans un endroit accessible. La deuxième étape consiste à connecter une source d'énergie à l'extrémité de connexion du câble électrique après que la glace a bloqué l'ouvrage de drainage et à alimenter en énergie le câble électrique, de sorte que l'énergie générée par le courant passant dans le câble électrique crée un passage d'écoulement dans la glace qui bloque l'ouvrage de drainage.
