Pavement Friction Measurement with Digital Imaging

The International Friction Index (IFI) provides a "universal translator" to allow comparison between results obtained with various measurement devices. Despite such advancements, actual testing of pavement frictional characteristics remains low, particularly at the municipal level that is collectively responsible for 75% of the total road network in Ontario. One problem is there are currently no measurement devices providing both high volume and low cost data collection under the erratic traffic flow found in the municipal environment. A multiphase effort is underway at Carleton University to address this issue using digital image analysis, which is able to capture all aspects of the pavement surface including micro and macrotexture, as well as provide an archival record. This paper includes the results of 2D analysis of historical asphalt pavement images using grey level co-occurrence matrices, as well as a multi-scale pattern analysis using sliding-box lacunarity. Results indicate that lacunarity analysis provides valuable information concerning the distribution and grouping of particle sizes at the pavement surface. Features of the lacunarity graphs are correlated with asphalt surface features, as well as locked-wheel skid numbers at 50 and 100 km/hr, although the correlation is less than desirable. Future work will involve 3D analysis to improve accuracy.
