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? Below is simple chart and accompanying sketches to show the minimum guidelines for radii for various PermaTrak tread sizes.
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.
