Horizontal Alignment - Minimum Radii
PermaTrak's skewed treads allow designers to incorporate curving sections of boardwalk into their trail or greenway projects. How can you know if a PermaTrak boardwalk will allow for a tight enough radius to match your trail's intended alignment?
Curved alignments are accommodated by creating a series of wedge shaped treads. The degree of a turn is unlimited and simply depends on the quantity of wedge shaped treads.
Horizontal alignment on a PermaTrak structure can be achieved with a curvilinear or deflection angle approach. A curvilinear approach uses wedge-shaped treads to approximate the trail alignment. A deflection angle approach uses sharp instantaneous turns to reroute the centerline.
PermaTrak has the flexibility to allow the design to decide which method is best for the project.
