GEOWEB 3D System Stabilizes FEC Intermodal Container Transfer Facility

PROJECT SUMMARY

The GEOWEB® system, consisting of a 6-inch deep mid-size cell over a high strength woven geotextile, was installed on each side of the 4 roller compacted concrete (RCC) gantry crane ways at the Port of Everglades, FL intermodal container facility.  The GEOWEB system is used to control differential settlement on the areas adjacent to the crane ways.  The crane ways consist of 18 inches of RCC installed on sheet piles 7 ft. on center.  The infill specified for the GEOWEB system was ¾ inch limerock with limited fines to allow drainage.  With the unique benefits of GEOWEB confinement, the contractor was allowed to substitute a lesser quality, on-site fill material which  resulted in  of coarse, screened sand.

Maintenance Reduction in High Impact Zones

The FEC was one of the first port facilities in Southeast Florida to use roller-compacted concrete (RCC)

PROVEN SOLUTION

The GEOWEB system is a thirty year proven solution for heavy load applications over soft subgrades in the rail/intermodal industries. The 3D confinement system solves soft soil challenges for roadways, intermodal/port yard surfaces, bridge abutments and high-stiffness trackbed foundations.

PAVEMENT PERFORMANCE

The GEOWEB solution behaves like a semi-rigid slab which improves load distribution and reduces vertical stresses reaching the sub grade.  The end result will be a more durable sub grade that increases pavement life by preventing long term settlement and consolidation.

Presto Geosystems’ GEOWEB® system offered a solution for stabilizing sand infill and preventing long-term differential settlement in the gantry crane ways located under the Roller Compacted Concrete (RCC).
