ROSANNE is a Collaborative project in the Seventh EU Framework Programme which aims at developing/harmonising measurement methods for skid resistance, noise emission and rolling resistance of road pavements as a preparation for standardization. To achieve this, the project will follow the recommendations of key predecessor projects (like TYROSAFE, HERMES, SILVIA, SILENCE and MIRIAM), as well as consider ongoing work in CEN and ISO. The project will develop/improve standards in the field of working group CEN/TC 227/WG 5 and in some cases ISO groups with which CEN cooperates. Special focus on pre-normative research must be devoted to rolling resistance of pavements. More specific objectives are:

  1. Skid resistance: The harmonisation of skid resistance measurement following the TYROSAFE Roadmap, by deriving conversion factors for friction indices based on similar groups of devices, namely longitudinal and sideways skid resistance measurement devices.
  2. Noise emission: Combining the existing measurement methods (SPB and CPX) into a harmonised pavement noise emission characterisation method. An evaluation of its viability for acceptance testing, monitoring and compatibility with environmental noise calculation methods like CNOSSOS-EU will also be carried out. Remaining problems with the method, such as the influence of temperature, will be addressed and solved.
  3. Rolling resistance: building on the results obtained in MIRIAM and standardising trailer measurements of rolling resistance coefficients of road surfaces. To this end, it is also necessary to study the influencing road surface parameters and factors which disturb such measurements and in some cases to develop correction procedures for such influences.
  4. Texture: exploring the potential for recent developments in the measurement of surface texture to deliver parameters that better reflect the physical process of tyre/road interaction and that may improve our understanding of how the texture influences skid resistance, noise emission and rolling resistance.
  5. Reference tyres and pavements: Defining and investigating the performance of reference tyres and pavements necessary for the measurement of all three road surface properties. This is a prerequisite for the harmonization of all future measurements.
