Abstract:

In this report, an application using polyurethane void filling and particle bonding technology for stabilizing ballast is ; evaluated. Application of rigid-polyurethane foam (RPF) as an in situ stabilization method does not require premixing ; with aggregates, soil, or with water, would not require track shutdown, and reaches 90% full strength in 15 minutes after ; application. PSB is found to have suitable mechanical properties for use as a material in track-substructure. Ease of ; injection and negligible curing period for PSB makes it an attractive option for railway maintenance, especially for timesensitive ; maintenance activities, such as intersections and bridge approaches. Use of PSB stemming from the research ; presented in this report can serve as an economically feasible/favorable maintenance approach compared with traditional ; methods, such as undercutting, track raising and ballast addition, tamping, etc.; especially for preserving uninterrupted ; track operations during track stabilization/enhancement.
