Abstract

L'invention concerne un procédé destiné à comprimer un ballast (5) au moyen d'un groupe de bourrage (7) comprenant deux outils de bourrage opposés (8) qui, au cours d'un processus de bourrage (9), sont abaissés vers le ballast (5) sous l'action de vibrations (13) et rapprochés l'un de l'autre à l'aide d'un mouvement de serrage (18). À cet effet, au moyen de capteurs (20, 22, 24) disposés au niveau du groupe de bourrage (7) au moins pour un outil de bourrage (8) pendant un cycle de vibrations (29), une variation (28) d'une force (21) agissant sur l'outil de bourrage (8) sur un trajet (23, 27) parcouru par l'outil de bourrage (8) est détectée, dont découle au moins une grandeur caractéristique (31-40) au moyen de laquelle est réalisée une évaluation du processus de bourrage (9) et/ou d'un état du ballast (5). De cette manière, le groupe de bourrage (7) est utilisé en tant qu'appareil de mesure pendant une application opérationnelle.
