Toolbox, review of functional triggers : Selection of maintenance candidates
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- ToolBox aims at developing a “concept for proper maintenance planning” to assure the selection of adequate maintenance works (“schemes” or “objects”) to make effective use of the maintenance budget, based on available road condition data, to give minimal negative effects on road users, safety for road workers and the environment. This report covers the first phase of the ToolBox findings and development. In chapter 2 there are a discussion on technical parameters and the use of them. This is followed with a listing of available technical parameters in the partner countries, chapter 4. A state of the art covering how selections of maintenance candidates are done in the respective countries follows including a comprehensive reporting of indicators and parameters available. Finally the chapter 6 covers the selection of models that will be used to evaluate the functional performances decided.

Förslag till index för att beskriva belagda vägytors tillstånd
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Historiskt har tillståndet på det svenska statliga vägnätet redovisats med mått på ojämnheter i tvär- och längsled (Spårdjup max respektive IRI (International Roughness Index). Successivt har dock nya mått och flera mått utvecklats för att beskriva tillståndet, samtidigt som detaljeringsgraden ökat. Det innebär att komplexiteten ökar och att det blir svårare att få en överskådlig och lättfattlig bild av tillståndet. Graden av detalj beror ju på till vilket ändamål beskrivningen ska användas till. Det finns ett behov att kunna redovisa tillståndet på ett överskådligt sätt. Syftet med detta projekt är att med hjälp av index beskriva vägnätets tillstånd på ett enkelt och översiktlig sätt.

Konferensbidrag (refereegranskat)abstract
- Maintenance of paved roads is carried out to preserve and improve the pavement and reduce the deterioration process. An adapted treatment will make the pavement last for a certain time interval before next treatment is necessary. Pavement managers deal with complex decisions when identifying lengths of their networks in need of maintenance and selection of the appropriate maintenance treatments.Decades of road network monitoring and follow up projects have generated a huge volume of empirical data on pavement condition. To complement this information, several decades of research and development has accumulated a substantial volume of knowledge, models and tools that can use the information to assist in maintenance decisions. Even so, these support tools are not yet implemented to their full potential, and most tools do not address user expectations and new environmental impacts such as fuel consumption and emissions. This paper will demonstrate a tool to assist road authorities in optimising the maintenance of their road networks.
