The skid resistance of road surfaces generally deteriorates over time. A number of laboratory tests have been developed to predict the long term in-field skid resistance of road surfaces, such as the Polished Stone Value (PSV) test, the Wehner/Schulze (WS) test and the Auckland Pavement Polishing Device (APPD) test (which is used in conjunction with the Dynamic Friction Tester (DFT)). Previous research conducted in France has shown that the WS test results reflect in-field skid resistance evolution. This finding has yet to be confirmed for New Zealand road surfaces. In New Zealand, routine skid resistance monitoring of state highways is undertaken annually using the Sideways Force Coefficient Routine Investigation Machine (SCRIM) device, which reports the skid resistance measured as the Sideways Force Coefficient (SFC). The historical annual surface condition data was extracted to obtain the in-field evolution relationships of a number of road sections in the Auckland and Waikato regions that were constructed using three geologically sourced natural aggregates; one Greywacke, one Basalt and one Andesite. SFC evolution curves were plotted against the accumulated heavy commercial vehicles (HCVs). A comparison was made between the in-field skid resistance and the predicted in-field skid resistance data derived either from WS or APPD laboratory tests. It was found that there is a good comparison between the two sets of data. Results are discussed in terms of using laboratory tests to predict in-field performance.
