NATIONAL CENTER ON ACCESSIBILITY
The impetus for the National Trails Surface study was to investigate alternatives to the typical firm and stable surface materials of asphalt, concrete, or boardwalk. It is a common misconception that in order to make a trail surface firm and stable, it needs to be paved. Professionals have found that using soil stabilizers, or natural aggregates, can be effective alternatives to creating a trail surface that meets accessibility guidelines (Boone, 2008).
