The right choice of structure and constituent layers is a primary concern to designers in both the private (engineering consultants, architects) and the public sector (technical departments of municipalities, provinces and regions) who have to make designs for new roads or for maintenance, renovation and adaptation works to existing infrastructure.
The Portable Friction Tester allows continuous measurements of the skid resistance of road markings and road surfaces over a given distance, in situations where the British pendulum tester (portable skid resistance tester) cannot be used.
The everyday life of road workers is often fraught with danger. High travel speeds and disrespectful drivers are an unwanted component to the environment of road workers, making it difficult for them to accomplish their tasks. High speed means there is little time for the driver to detect the work zone and, in event of an accident, the consequences will be more severe.
After developing a harmonized frameword for collecting data on accidents (due to interaction with traffic) involving road workers, the BRoWSER project will provide road authorities with the necessary tools for collecting and presenting such data.
The ASAP project addresses the issues of speed management in work zones. Speed management of traffic in work zones is important for the safety of both the road user and road worker. A work zone will introduce deviations from normal travel in a discrete road section and appropriate speed is needed to ensure that the driver can navigate the vehicle through the work zone, particularly if there are abrupt lateral deviations from general road design standards.
The aim of STARs project was to optimize network availability, road worker safety and road user safety during road works. The objective was to develop a methodology to score road work schemes on these three interdependent risk areas which are usually considered in isolation, and to produce a practical tool for use particularly by contractors and contracting authorities in planning and assessing road work schemes and setting contractor targets. To achieve this objective, three risk equations for performance at road works have been developed and included in the STARs Evaluation Tool, together with a Multicriteria Solver Module to transform the scores into a “STARs” scale. This scale is used to produce an unbiased rating of individual management strategies.
• Iatroscan (picture: MK-6s TLC-FID Analyser) is a chromatographic analysis technique for the characterization of bituminous binders. This technique is based on the separation and quantification of the main components of bitumens (saturated compounds, aromatic fractions, resins, asphaltenes). This affords better understanding of the chemical composition of bitumens (origin, compatibility with polymer additives, etc.) and of modifications induced by external factors such as exposure to air (e.g., during the ageing of binders). The technique can also be used for the quantification of additives in (mastic) asphalt produced at a reduced temperature.
Iatroscan is complementary to other techniques for rheological or mechanical characterization available at BRRC.
