Status of the EU-project ROSANNE

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 is following the recommendations of key predecessor projects like TYROSAFE, HERMES, SILVIA, SILENCE and MIRIAM as well as considering the ongoing work in CEN and ISO groups. Work package 1 deals with skid resistance and aims at the harmonization 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. During the first project year a first round robin test was carried out in Nantes, ten different devices participated to the test. The results of this test are collected in report D1.2 “Analysis of data from the first round of tests and initial development of the common scale”. Work package 2 is dealing with the pavement influence on road traffic noise emission: the main objective of this work package is to combine the existing measurement methods of SPB (ISO 11819-1) and CPX (ISO/DIS 11819-2) into a stable and reliable harmonised pavement noise emission characterisation method. The project is validating procedure incorporating correction mechanisms for temperature influence and investigating its potential use for noise calculation methods like the one proposed by the CNOSSOS-EU project. Work package 3 is dealing with rolling resistance, where the ROSANNE project is mainly building on the results obtained in the MIRIAM project and is considering standardized trailer measurements of rolling resistance coefficients of road surfaces. After a first report D3.1 “State of the art on rolling resistance measurement devices including draft standard outline” the following main report was produced “Parameters influencing rolling resistance and possible correction procedures”. In the frame of work package 4 the project is also exploring the potential for developments in the measurement of surface texture in order to find out parameters that better reflect the physical process of tyre/road interaction and that may improve the understanding of how the texture influences noise emission, skid resistance and rolling resistance. In addition to that this work package is also investigating the performance of reference tyres and pavements which are necessary for the measurement of all three road surface properties. The present paper summarizes the project status after the first 18 project months.
