REPORT NUMBER: R-479
SUBJECT: Tracks & Structures
KEYWORDS: Bending Stiffness, Rotation Resistance, Torsional Rigidity
ABSTRACT: This report describes the test procedures and results from a series of tests on the physical properties of concrete ties, rails, joint bars and rail fasteners, conducted at the Association of American Railroad's Track Research Laboratory in Chicago, Illinois. The properties investigated were: torsional rail rigidity, bending stiffnesses of concrete ties and joint bars, and rail fastener resistance to rotation about the vertical, lateral and longitudinal axes. The tests involved 115RE and 136RE rail sections, six types of concrete ties, 136RE section joint bars, five fastener configurations for the two rail section on wooden ties, and two fastener configurations for two rail sections on concrete ties.
