  An Analysis of Walkway Surface Micro Roughness and its Impact on Human Slip Potential
  Author(s): Anthony Marletta*
  
  The purpose of this study was to analyze three different floor surfaces (ceramic tile with a polished finish, ceramic tile with a matte finish, and a porcelain enamel bathing surface) with varying degrees of floor surface microroughness measured in both the Rz and Ra roughness parameters to identify relative safety thresholds for various floor surfaces. Porcelain enamel and ceramic surfaces were sandblasted to systematically alter the microroughness on the surface samples. Twelve different surfaces were generated under the sand blasting process, with each sample type having four different levels of surface microroughness as measured by a stylus profilometer in both Ra and Rz parameters. This created 15 different surfaces in total to be measured by three tribometers (BOT 3000E, English XL VIT, and Slip-Test Mark IIIB) with four tribometer users. The surfaces were then measured by the t.. View More»
