Permeable Aggregate Roads Offer High Environmental Benefits; With Low Environmental Impact.

Presto Geosystems’ GEOWEB® Load Support System offered a load distribution system on two low water crossings for Florida Power & Light (FP&L). With FDOT #57 stone (crushed limestone) infill, the system creates a stable mat to support FP&L’s line trucks over wet, soft soil areas. The GEOWEB® 3D Confinement System creates a permeable pavement capable of supporting vehicular loads over non-load-supporting soils and functions as a stormwater retention system.

Geosynthetic Project Components:

• GEOWEB GW20V 6-inch Depth
• Geotextile Separation Layer

GEOWEB Low Water System Environmental Benefits

With Clean Aggregate Infill, the System:

• Confines granular infill, significantly improving load distribution.
• Reduces stormwater runoff, promoting groundwater replenishment.
• Functions as a natural stormwater retention system, allowing water to fill the aggregate voids and permeate into the existing ground.

Other Benefits:

• Cell wall perforations facilitate lateral cell‐to‐cell drainage beneath traffic areas, resulting in better performance in oversaturated soils.
• The stability of the pavement surface translates to a reduction in maintenance costs.
• Controls shearing and lateral movement of infill material.
• Supports the weight of vehicles and greatly reduces the compaction of underlying soils.
• Confinement provides additional structural strength allowing for a reduction in overall cross‐section (50% or more).
