Abstract
A method for compaction of a track ballast bed uses a tamping unit including two oppositely positioned tamping tools which are actuated with vibrations and are lowered into the track ballast bed during a tamping operation and moved towards one another with a squeezing motion. A progression of a force acting upon the tamping tool over a path covered by the tamping tool is recorded during a vibration cycle by sensors disposed at the tamping unit for at least one tamping tool. At least one characteristic value is derived therefrom and used to carry out an evaluation of the tamping operation and/or of a quality of the track ballast bed. The tamping unit is thus used as a measuring apparatus during operative use. A device for performing the method is also provided.
