  1. A Longitudinal Study of Playground Surfaces to Evaluate Accessibility: Final Report

    In 2008, the National Center on Accessibility (NCA) at Indiana University initiated a longitudinal study of playground surfaces with research funding by the U.S. Access Board.  The purpose of this longitudinal study was to evaluate a variety of playground surfaces, their costs, and their ability to meet accessibility requirements while documenting deficiencies that arise upon initial installation or those that might require maintenance after a 3-5 year period of use.

  2. National Trail Surfaces Study

    Trails provide opportunities for people to connect with the natural environment in a variety of settings and are places for all individuals, including people with disabilities.  Individuals with disabilities have the same desire to explore nature and physical barriers such as inaccessible surfaces and routes can hamper or even prevent opportunities to participate in the outdoor leisure experience for people with a disability. The purpose of the longitudinal surface study was to evaluate a variety of trail surface materials, and their ability to meet proposed accessibility requirements of firmness and stability from initial installation and maintenance over 51 months.  

  3. A Longitudinal Trail Research Program on Soil Stabilizers

    The purpose of this project is to compare the effectiveness of surface treatments for creating a trail accessible to people with mobility impairments. Specifically, this study is examining the longitudinal effects of surface treatments on surface firmness and stability, the costs of applying the treatments, and their relative maintenance demands.
