21. Transportation asset management : Quality related accounting, measurements and use in road management processes
Abstract : Today there are shortcomings in monitoring, control, analyses, learning and reporting of the results of activities and operations in the road management processes. There are also shortcomings in transparency and verifiability, in knowledge of road management’s costs and life cycle costs, of the road capital’s standard and condition and in measures of quality deficiency costs, productivity and maintenance backlog.

22. Winter maintenance and cycleways
Abstract : Increasing cycling as a means of personal travel couldgenerate environmental benefits if associated with acorresponding decrease in car-based transport. In seeking topromote cycling in wintertime, it is desirable to understandhow important the road surface condition is compared to otherfactors in people's decision to cycle or not. READ MORE

23. Tyre-road Interaction: a holistic approach to noise and rolling resistance
Abstract : Energy dissipation, fuel consumption, real-estate property prices and health issues are some of the aspects related to the tyre/pavement interaction and its functional properties of rolling resistance and noise. The first two aspects are affected by the tyre/road interaction as energy is dissipated mostly by hysteretic losses as the tyre is subjected to dynamic deformations when contacting the pavement surface.

24. Utilizing solar energy for anti-icing road surfaces using hydronic heating pavement with low temperature
Abstract : During summer, the surface temperature of an asphalt road pavement can rise up to 70°C due to absorbed solar radiation. The high temperature degrades the performance of the asphalt concrete by accelerating the thermal oxidation and plastic deformation, especially under heavy traffic loads. READ MORE

25. Multi-year maintenance optimisation for paved public roads - segment based modelling and price-directive decomposition
Abstract : I avhandlingen studeras hur kostnadseffektiva underhålls- (uh-)planer för belagd väg kan genereras, på basis av information om aktuellt vägytetillstånd och funktionella modeller för kostnads- och tillståndsförändringar, delvis utvecklade i samarbete med svenska Vägverket (VV). Tilltänkt användning är på strategisk och programnivå, innan mer detaljerad objektinformation finns att tillgå. READ MORE
