This report provides the results of the longitudinal study of the firmness and stability of trail surface materials located at Bradford Woods, at Indiana University. It also provides the national survey results of trail managers administered by Oklahoma State University on the types and characteristics of trail surfaces currently being used around the country.
The following are the three research questions explored in “Section III: Result of the Study”:
- Does each of the 11 trail surface materials meet or exceed the classifications for firmness and stability as proposed by the US Access Board in their 2007 Notice of Proposed Rulemaking for Outdoor Developed Areas?
- When evaluating the firmness and stability of each of the 11 trail surface materials, how does each of the 11 trail surface materials compare to themselves over a 51 month time period?
- When evaluating the firmness and stability of each of the 11 trail surface materials, how does each surface compare to each of the other surfaces over a 51 month time period?
