About This Item
ASTM E3028 is a technical standard for computing a wheelchair pathway roughness index from longitudinal profile measurements, helping quantify how a pathway may affect comfort, passability, and whole-body vibrations. It provides a consistent way to interpret surface profile data for wheelchair travel assessment, which can support more objective engineering and accessibility decisions. As an ASTM standard, it is especially useful when comparing pathway conditions using a repeatable calculation method.
What is ASTM E3028?
ASTM E3028, titled Standard Practice for Computing Wheelchair Pathway Roughness Index as Related to Comfort, Passability, and Whole-Body Vibrations from Longitudinal Profile Measurements, defines a practical approach for turning profile measurements into a roughness index. The standard is focused on evaluation rather than design, and it is intended to help users assess how a pathway’s longitudinal profile may influence wheelchair movement and rider experience. It is commonly used as a technical reference for consistent analysis and reporting.
Where is ASTM E3028 used?
ASTM E3028 is typically used in accessibility-related pathway assessment, especially where longitudinal surface profile data are collected and analyzed for wheelchair travel. It may be applied to sidewalks, ramps, routes, or other pedestrian surfaces where comfort and passability need to be evaluated in a consistent way. The standard is relevant in engineering reviews, inspection workflows, and performance assessments that depend on measured surface profile data rather than visual judgment alone.
Why is ASTM E3028 important?
This standard helps support more objective and repeatable evaluation of wheelchair pathway conditions. By using a common computation method, ASTM E3028 can improve consistency in testing, procurement, and quality control decisions related to accessible routes. It also helps reduce ambiguity when comparing different pathway sections or project outcomes. For organizations that review compliance or assess ride quality, the standard offers a clear technical basis for reporting roughness-related performance.
