Capability Statement

GeoTT is a true triaxial testing rig used to test the performance of railway subgrade/ballast materials when exposed to railway traffic. It can apply unique loading conditions (rotation of principal stresses) to cubic material samples up to 400m3 in size. This simulates highly realistic moving train loads thus allowing for testing/validation of new subgrade materials. GeoTT is one of the largest true triaxial rigs in Europe.
