This research is part of the MIRIAM project (Models for rolling resistance In Road Infrastructure Asset Management systems), which aims at developing methods for improved control of road transport carbon dioxide (CO2) emissions in order to obtain sustainable and environmental friendly road infrastructure.

As a first part of MIRIAM, a “Phase 1” was conducted in 2010-2011. It is planned to start a “Phase 2” in 2012.

MIRIAM is divided into five sub-projects. Sub-project number 1 (SP 1) is designated “Measurement methods and surface properties model”, and lead by Ulf Sandberg, VTI. Within SP 1, one of the major tasks is to study various measurement methods and the performance of available measurement equipment for rolling resistance, with a focus on measuring the pavement properties. As part of this task, in 2011 an international experiment was conducted to compare the measurement devices available within the MIRIAM project. This comparison experiment was popularly called “Round Robin Test” (RRT), which is the name used in this report.

The RRT was organized from 6 to 10 June 2011 on the test track owned by IFSTTAR in Nantes, France. Three institutes participated with their rolling resistance trailers: BASt, BRRC, and TUG. The practical organization was coordinated by IFSTTAR and the technical organization by BRRC. Texture measurements were performed by BRRC to verify the homogeneity of the test sections. Measurements on drums in laboratories were performed by BASt and TUG with the same tyres as used in the RRT.

At a later stage also truck rolling resistance measurements were carried out on a smaller selection of surfaces on the test track in Nantes. However, when this report was written these measurement results were not yet available.

This experiment was, as far as the authors are aware, the first time when this type of devices was compared.

This report presents the RRT in terms of how it was carried out and the results obtained.
