1. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance
Abstract : Increased fuel consumption, increased greenhouse gas emission, diminishing real-estate prices and increased health issues are some of the negative effects on the climate, on the environment and on the society from tyre/road rolling resistance and noise. The first two aspects are affected by energy dissipation in the tyre/pavement contact and are related to rolling resistance. READ MORE

2. Road Surface and Tyre Interaction : Functional Properties affecting Road Dust Load Dynamics and Storage
Abstract : Luftburna partiklar (PM) är ett problem för människans hälsa, där flertalet samband mellan negativa hälsoeffekter finns mellan luftföroreningar finns, bland annat för respiratoriska sjukdomar, lungcancer och kardiovaskulära sjukdomar med flera. I länder där dubbdäck används, till exempel Sverige, Finland och Norge, och sandning av vägar och gator genomförs vintertid för att säkerställa god friktion kommer en betydande andel av partiklarna från vägslitage och nedkrossning av sand vilket bidrar till PM10.

3. Measurements for winter road maintenance
Abstract : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl). READ MORE

4. A Bayesian approach to retrospective detection of change-points in road surface measurements
Abstract : First-order autoregressive processes are analysed for sudden changes in parameter value. In its most general form, a multivariate vector of measurements is allowed, and no prior knowledge about the involved parameters is required. READ MORE

5. Cycle paths’ degradation processes and surface condition assessment
Abstract : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. READ MORE
