The aim of this project is to test and verify the method from Optimass work package 3 and to further develop the method so it can be implemented in the material handling in Trafikverket. The project will focus on "Clean" masses. The method from Optimass will be tested and verified in the Project "Tv�rf�rbindelse S�dert�rn". In the Optimass project, tools and solutions are developed in order to contribute to a more effective soil and rock material handling in the built environment. The overall purpose were to promote reduced costs, optimize transports and to develop Swedish knowledge and environmental engineering.
