This invention provides a method for restoring at least one means defining a railroad spike hole located in a used railroad tie. In this way, the restored railroad tie can be reused in subsequent rail replacement operations. The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems. The used railroad tie provided has at least one spike hole located therein. In each the means defining a railroad spike hole is formed a polymeric plug. The polymeric plug comprises a substantially non-foaming, non-cellular polymeric material. The polymeric material preferably comprises a polyurethane. The polymeric plug infiltrates and tightly bonds with the railroad spike hole to prevent moisture infiltration. Thus, substantial tie rot due to moisture is impeded, and the leaky railroad spike hole is effectively and efficiently dammed to enable complete filling thereof. The polymeric plug is capable of penetration by and retention of the railroad spike therewithin.

La présente invention a trait à une méthode de remise en état de traverses de chemin de fer présentant au moins un trou de crampon. La traverse remise en état peut être réutilisée lors de travaux de remplacement de traverses. Il est possible de faire pénétrer un crampon dans la traverse remise en état et de le maintenir dans le trou réalisé pour son passage dans la traverse, sans risque important de courbure. La traverse usée présente au moins un trou de crampon pouvant recevoir un bouchon polymère. Ce dernier est constitué d'un matériau polymère généralement non expansible et non cellulaire comprenant un polyuréthane. Le bouchon pénètre dans le trou de crampon et assure une bonne étanchéité afin d'empêcher l'humidité de s'y infiltrer. Ainsi, la pourriture de la traverse par l'humidité est entravée et le trou de crampon est étanchéisé de façon efficace et efficiente, puisqu'il est entièrement comblé. Le crampon peut pénétrer dans le bouchon polymère et y être maintenu en place.
