Physical Model for Studying the Migration of Fine

Aug 28, 2013In particular, the camera exposed the pumping up level of fine particles during the test, showing that the migration of fine particles was not only a result of the interpenetration of ballast particles and subsoil, but also of the pore water pressure that pushed the fine particle upward.

Ballast-Cleaning Machine Article about Ballast-Cleaning

Ballast-Cleaning Machine a track machine for cleaning ballast of contaminants, such as fine debris and dust, that lower the resiliency of the ballast layer and prevent the drainage of moisture. Ballast becomes contaminated because the gravel is abraded and crushed by the dynamic loads of passing trains and compacted under railroad ties during track
