RESULTS FROM CALDWELL, TEXAS GEOTEXTILE TESTS ON SOUTHERN PACIFIC

Because of evidence of the effectiveness of fabrics in track structures, but faced with a lack of knowledge of the precise mechanisms of fabric behavior in railroad applications, Monsanto Textiles approached Southern Pacific with a proposal for a full scale test program in which geotextiles would be evaluated using an instrumented track structure. A siding at Caldwell, TX, has six 300-ft test segments where four polyester and polypropylene fabrics are compared with a cement-stabilized section and a conventional track structure. Instrumentation is designed to follow loads from top of rail through the track structure and into subgrade. Fundamental mechanisms of fabric behavior are now being identified.
