Summary: | The invention is applicable to rail infrastructures consisting of aggregates with a particle size distribution of between 25 mm and 100 mm, individually covered with a first solidified polymer layer (2) comprising an incorporated granular elastomer material (3) with granules smaller than 4 mm, preferably smaller than 2 mm, and optionally having a second covering polymer layer (4).
Aplicable a infraestructuras ferroviarias compuesto de áridos de granulometría seleccionada de entre 25 mm y 100 mm recubiertos individualmente con una primera capa polimérica solidificada integrando dicha primera capa polimérica (2) un material elastomérico (3) granular, con gránulos de un tamaño inferior a los 4 mm, y de forma preferida inferior a los 2 mm, y estando dotado opcionalmente de una segunda capa polimérica (4) de recubrimiento.
Ce ballast est applicable à des infrastructures ferroviaires, et se compose de granulats d'une granulométrie sélectionnée entre 25 mm y 100 mm, recouverts individuellement d'une première couche polymère (2) solidifiée laquelle contient un matériau élastomère (3) granulaire dont les grains ont une taille inférieure à 4 mm, et de préférence inférieure à 2 mm, et éventuellement dotés d'une seconde couche polymère (4) de revêtement. |
