Heavy-Duty Pavements

 

Heavy-duty pavement structures pose a particular set of challenges to the designer. These may include for example, accounting for an excessive number of equivalent standard axle passes (ESALs) in say a busy warehouse facility where heavily loaded trucks are coming in and out all day. Alternatively, the individual axle loads may themselves be excessive. In a port or intermodal facility for example, axle loads for front end loaders may be 10 to 15 times that for a conventional highway truck.

The use of geogrid technology to enhance the performance of these structures dates back more than thirty years. When used to reinforce the unbound aggregate base layer, the stiffness enhancement provided can be used to reduce the thickness of the pavement or extend its design life.

Scope

  • Warehouse facilities
  • Truck stops
  • Intermodal yards
  • Ports
  • Flexible or rigid pavements

Benefits

  • Reduce initial construction costs
  • Extend life of pavement structure
  • Develop cost-neutral road solutions with “free” life extension
