Field Demonstration of Geocell Track Substructure Support System Under High-Speed Passenger Railroad Operations

Regions of track, which experience high rates of track geometry degradation, tend to require frequent maintenance interventions that are typically surfacing or tamping. Harsco Rail and the University of Delaware conducted a survey regarding this costly process that involved both machine time and track time to complete. A region of track on Amtrak’s Northeast Corridor (NEC) (Oakington Road, Havre de Grace, MD—Milepost 63.7) was selected to have a geocell-based subgrade stabilizing material installed as part of a subgrade renewal project. This report describes the renewal of the track region as well as the experimental setup, data, and results used to quantify the effectiveness of the geocell material and maintenance activity.
