A Functional Analysis of Slip Resistance Properties of the Floor Surfaces
This study was concerned with operationally modified geometric features of the floor surfaces during slip resistance measurements from a functional point of view. When analyzing surface structures of the floors, it was commonly found that measurements of surface profiles showed almost identical values of roughness parameters such as Ra (centre line average) and Rtm (maximum mean peak-to-valley height) but with different profile forms due to their distinctly different friction and wear characteristics. Hence, it would be desirable to find a systematic way to evaluate the surface profiles more accurately. A concept of the bearing area (BA) curve was applied to assess exclusively operating behaviors of the floor surfaces during slip resistance measurements. This concept was also aimed to identifying main tribological characteristics of the floor surfaces as a result of frictional interactions and wear developments during slip resistance measurements. For slip resistance measurements, ceramic plates were rubbed against two double density Polyurethane shoes under dry conditions. The overall results clearly showed that truncations took place at the actual contacting areas of the floor surfaces. It was also found that the bearing areas would provide vital information about the sliding mechanism of the interaction between shoe heels and floor surfaces during the slip resistance measurements.
