Compaction control with the DTS


Figure: Plasser & Theurer

The ballast of a railway track needs to bear heavy horizontal and vertical loads.

Therefore the ballast has to be very dense. If this is not the case – i.e. after tamping or when the railway track is new – speed restrictions are required.

To avoid these restrictions, the ballast can alternatively be compacted with the Dynamic Track Stabilizer (DTS).

Currently the only way to check the compaction of the ballast is the measurment of the static lateral resistence of a sleeper.

The aim of the research project is to develop a system for continuous compaction control of the ballast based on dynamic measurements on the DTS and to optimize the compaction process of the DTS.
