INVESTIGATION ON THE DURABILITY OF TEST RAIL PADS BY THE FIELD AND QUALITY TESTS

Tie pads for concrete cross ties and for concrete-slab track reduce track degradation and maintain resistivity to assure operation of the signal circuits. These pads, once made of natural rubber are now made primarily of synthetic rubber, were examined in the course of developing new rail fasteners and new track structures. Results of several quality tests and of the degradation of these pads in long field service are given.
