- Description
- Railway transitions experience differential movements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade settlement. This differential movement is especially problematic for high speed rail infrastructure as the ‘bump’ at the transition is accentuated at high speeds. Identification of different factors contributing towards this differential movement, as well as development of design and maintenance strategies to mitigate the problem is imperative for the safe and economical operation of both freight and passenger rail networks. This paper presents the research framework and initial instrumentation details from an ongoing research effort at the University of Illinois at Urbana-Champaign. Three bridge approaches experiencing recurrent geometry problems were instrumented using multidepth deflectometers (MDDs) and strain gages to identify different factors contributing to the development
of differential movements.

- Description
- The objective of this paper is to present a procedure for high sheet temperature air channel testing of dual track thermal seams for 0.75 mm thick PVC geomembranes. This objective is accomplished by developing relationships between seam peel strength and seam burst pressure for sheet temperatures ranging from 46.7C to 62.8C during field air channel
testing. This paper extends the original relationships presented by Thomas et al. (2003a) and Stark et al. (2004) that only extend to 46.7C because a sheet temperature greater than 46.7C is frequently encountered during hot summer months. The original relationship is extended to 62.8C using the Arrhenius model and a polynomial equation is presented that can be used to convert the sheet temperature during field air channel testing to the air channel pressure required to ensure the specified seam peel strength of 2.6 N/mm (15 lb/in) is met or exceeded. Thus, the proposed relationship and equation allow the seam peel strength to be verified by field air channel testing without conducting destructive tests.
