On the other hand, with the faster traveling and more comfortable for passengers, railway in service have to be kept in a good state, which must be guaranteed by dynamic tests on their conditions and distress and related maintenances and repair in time. So that subgrade engineering has a bright future and Subgrade Web be found.
