JOINT BARS-DESIGN SPECIFICATIONS AND SERVICE TESTS INCLUDING INSULATED JOINTS AND COMPROMISE JOINTS

Various tests and application procedures of joints are discussed. Insulated joints, glued joints, web-contact joint bars, Huck fasteners, and joints with structural adhesives are studied in service tests, both in the laboratory and in field installations. The field installations are varied in location. Static stresses in rail and dynamic stresses in rail joint are studied in connection with field installations Huck fasteners. Among the conclusions are: 1)service tests of redesigned vulcabond insulated joints showed much chipping and flaking off; 2) Huck fasteners on polyurethane insulated joints were in satisfactory condition after two to twelve months installation; 3) Huck fasteners in standard head-free toeless angle bars would not satisfactorily restrain rail movement.
