Abstract

Un paso a nivel de concreto prefabricado incluye una pluralidad de miembros base (18) cada uno de los cuales tiene un hueco central formado en la superficie superior del mismo. Un par de rieles (12, 14) se encierran cada uno por una cubierta (48) de caucho que se extiende a través del cruce de una pieza continua individual. Los miembros encerrados en la cubierta se reciben en el hueco que incluye un resalto (52) a lo largo del lado exterior de cada riel (12, 14). El resalto (52) se soporta contra un borde (50) de la cubierta (48) que se extiende hacia arriba a lo largo del lado exterior de la cabeza del riel (12) para prevenir que la humedad entre al espacio entre la cubierta (48) y el riel (12) por abajo del resalto (52).
