Transverse strength of railway tracks: part 2. Test system for ballast resistance in line measurement
In the present paper, testing methods currently adopted to measure the in service ballast resistance are synthetically reviewed to identify the main sources of uncertainty influencing the test loads and to define an experimental methodology allowing the optimal control of the testing parameters with...

| description | In the present paper, testing methods currently adopted to measure the in service ballast resistance
are synthetically reviewed to identify the main sources of uncertainty influencing the test loads and to define an
experimental methodology allowing the optimal control of the testing parameters without the introduction of
spurious or parasitic actions on the track sample. An alternative testing system, which allows applying on a fullscale
sample of a railway track testing loads very close the real ones, is presented. Of the new system, both the
ways of use for measuring the transversal and axial ballast strength, the general procedure to carry out the
experimentation and its application to a real scenario are described, highlighting its main advantages in terms
both of modalities for applying the loads and of testing parameter control. |
