DEVELOPMENTAL TESTS OF CONCRETE TIE AND TIE FASTENING SYSTEMS

This report covers a series of laboratory investigations into improved techniques for fastening rails to concrete railroad cross ties. Past experience with several fastening designs in North America had pointed out certain areas of deficiency. Several concepts were developed which were intended to improve this performance. The laboratory experiments were a first step in testing these concepts. Some of the designs and concepts tested were found to be ready for field testing while others demanded further development efforts. The tests included measurements of vertical, longitudinal and lateral rail restraint, electrical characteristics and stress determinations. The results are given in tabular and graphical form.
