Pervious Concrete Surface Characterization to Reduce Slip-Related Falls

Abstract

This paper presents results from a unique study that employed biomechanical evaluation techniques to assess the slipping behavior of traditional and pervious concrete pavements under icy conditions. Gait motion analysis using embedded force plates, electromyography, and tracking videography were used to analyze subject mobility of on icy and wet pervious concrete. Results show that pedestrian contact pressure on pervious concrete is more than twice the pressure on traditional impervious concrete. In slippery conditions, the pervious concrete specimens had more controlled gait cycles and reduced slipping. The unique surface characteristics combined with high permeability reduces surface icing, suggesting that pervious concrete offers superior slip resistance in inclement weather.
