German Unity Transport Project 8

 Nuremberg – Erfurt – Halle/Leipzig – Berlin

The basic principle

The material excavated when cuttings are created is used to build new embankments. This is cohesive, clayey soil so it has to be improved before it is used. It is treated using binding agents to bring it up to the required quality for earthworks. The untreated soil and the subsequent mixture of soil and binding agent are examined and tested extensively in order to achieve this. The specific properties of the material are thus constantly monitored.
