Project Name: Cleveland Hopkins International Airport

Project Location: Cleveland, OH

PROJECT SCOPE

The GEOWEB® Load Support System was utilized for a 1.3 million sq ft. de-icing area at the Cleveland Hopkins Airport. The system serves as a construction support platform over marginal subgrades and a highly-permeable structural drainage layer for the 30-acre de-icing site. Confinement in the interconnected cells stabilizes aggregate so it can handle the heavy loads of construction and commercial aircraft.

  • Develops a structurally-stable aggregate drainage system for groundwater, and supports the impervious membranes that prevent the possibility of groundwater contamination.
  • Stabilizes aggregate so it can handle the heavy loads of construction and commercial aircraft.
  • Controls surface rutting and distribute heavy wheel loads.
  • Functions as a drainage layer when backfilled with an open aggregate.
  • Cost-effective alternative to conventional concrete or bituminous concrete.

GEOWEB LOAD SUPPORT SYSTEM STRUCTURAL BENEFITS

  • Confines aggregates, preventing shear failure and both lateral and vertical movement of the infill material.
  • Creates a stiff load distribution system, effectively reducing subgrade contact pressures and vertical deflections.
  • Controls differential and total settlement over low-strength subgrades.
  • Thickness and weight of confined vs. unconfined structural support systems may be reduced by 50 percent or more.

GEOWEB SYSTEM ENVIRONMENTAL BENEFITS

  • Eliminates the need for excessive excavation while increasing structural capacity, which saves construction costs.
  • Permeable system minimizes surface runoff and maximizes groundwater replenishment.
  • Functions as a natural storm water retention system with storage capacity, allowing water to fill the aggregate voids and permeate into the existing ground.
  • Supports the weight of vehicles and greatly reduces the compaction of underlying soils.
  • Cell wall perforations facilitate lateral cell-to-cell drainage beneath traffic areas, resulting in better performance over saturated soils.
  • Stability of the permeable pavement surface translates to a reduction in maintenance costs.
