Title
(EN) RAIL TREATMENT METHOD, COMPOSITION AND APPARATUS
(FR) SYSTÈME DE TRAITEMENT DE RAILS
Abstract
(EN) A method of treating a rail (R1, R2), e.g. of a railway track, for reducing its propensity for undergoing thermally-induced buckling, comprising applying to at least a portion of a surface of the rail (R1, R2) a thermally-insulating composition comprising particles of a thermally insulating material, e.g. porous expanded recycled glass particles, beads or granules, and a matrix material, e.g. a polymer resin or binder material.
(FR) L'invention concerne un procédé de traitement d'un rail (R1, R2), par exemple d'une voie ferrée, pour réduire sa propension à subir un flambage induit thermiquement, comprenant l'application sur au moins une partie d'une surface du rail (R1, R2) d'une composition thermiquement isolante comprenant des particules d'un matériau thermiquement isolant, par ex. des particules, billes ou granules de verre recyclées expansées poreuses, et un matériau matrice, par ex., une résine polymère ou un matériau liant.
