Subject(s): Online resources: Abstract: The introduction of laser-based measurements of pavement texture has provided a more appropriate measurement as these can be carried out in normal traffic. Hence the use of texture measurements as a screening tool for friction measurements has been considered and implemented in Denmark, where Mean Profile Depth (MPD) in accordance with the ISO standard ISO 13473-2 is used as a representative of the pavement texture property. However, Danish experiences have shown that using MPD as a screening tool is related to a certain lack of precision, due to the different mechanisms affecting the physical friction properties between a pavement and rubber testing tyre. The Danish Road Institute (DRI) performed a series of tests in the Danish county of Vi-borg in 2002 and has worked on creating a better understanding and use of the information retrieved by the measured texture profile. This report describes the status of the work conducted at DRI and the recommendations for future work.
