GEOWEB 3D System Stabilizes Maintenance-Prone Ballast at Florida Bridge Abutment 

PROJECT OVERVIEW

Florida East Coast Railway (FEC) headquartered in Jacksonville, Florida operates 351 miles of mainline track along Florida’s east coast. FEC is the exclusive rail provider to South Florida’s ports and connects with other railway systems to move freight around the country.

A portion of FEC’s track along Griffin Road in Fort Lauderdale had been a high maintenance area for many years due to high impact loads from rail cars transitioning off of a concrete bridge abutment onto ballasted concrete ties placed over soft sub grade with a history of pumping. FEC required a solution to eliminate the maintenance area due to pumping of the soft sub grade.

GEOWEB® TRACK STABILIZATION SYSTEM

The GEOWEB system was selected by FEC based on Presto’s 30 years of rail industry use and independent testing conducted in 1998 at AAR FAST High Tonnage Loop in Pueblo, CO. The testing examined soft sub grade solutions for tracks subjected to heavy loads and determined that the GEOWEB load support system significantly improves load distribution, therefore reducing the vertical stresses reaching the sub grade. The system’s three-dimensional structure performs like a semi-rigid slab.

The end result is a more durable sub grade that increases railway life by preventing long term settlement and consolidation. The ability to quickly install GEOWEB panels and limit the track downtime was critical in maintaining operations.
