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