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 as well as consider ongoing work in CEN and ISO. The project wi...

This work develops a method to inspect the quality of pavement conditions based on images captured from moving vehicles. This task is challenging because the appearance of road surfaces varies tremendously, depending on the construction materials (e.g., concrete, asphalt), the weather conditions (e.g., rain, snow), the illumination conditions (e.g., sunny, shadow), and the interference of other...

Figure 31 TEM micrographs of water borne polymer nanocomposite (WB PNC) emulsions.49 Figure 34 The reaction of an isocyanate with a compound containing hydroxyl functionality results in the formation of a polyurethane.. Introduction Coal tar is derived from crude coke oven tar that is a by-product of the combustion of coal in steel manufacturing. The crude coke oven tar is then refined, through...

An analysis of the use-stage for pavement life-cycle assessment (LCA) is presented within a framework of an LCA tool developed for Illinois Tollway. Methodological choices that can significantly affect LCA results were evaluated in this study. The share of the use-stage in a comprehensive pavement LCA framework was evaluated with all life-cycle stages including materials, construction, use, mai...

Tire rolling resistance has a significant influence on fuel consumption in cars and trucks CO2 emissions. Rolling depends the tire construction, pavement texture stiffness, as well environmental traffic conditions. This article presents pilot study impact of passenger car tires. Reasons why Mean Profile Depth is not good descriptor characteristics from point view are presented, an experimental ...

This paper presents some results of a study, which aimed at modelling pavement evolution by different methods. In a first part, a database was constituted with data collected on French roads in the last decades. The database contains skid resistance values (Sideway Force Coefficient measured by SCRIM/Sideway force Coefficient Routine Investigation Machine), macrotexture values (Mean Profile Dep...
