6. Road Surface and Tyre Interaction : Functional Properties affecting Road Dust Load Dynamics and Storage
Sammanfattning : 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.

7. Investigation of the structural response of pavements in cold region using instrumented test site data
Sammanfattning : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. LÄS MER
8. Validation of heavy vehicle loading responses and temperature predictions in flexible pavements using field data
Sammanfattning : It is well established that both traffic-related loading and environmental conditions influence the structural behaviour of pavements. Pavement design methods aim to consider the effect of traffic loading and environmental variables on pavement structure, foresee their changes during the lifetime of the pavement and predict the resulting distresses and pavement life.

9. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance
Sammanfattning : 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. LÄS MER
10. In-plane mechanical properties of birch plywood and its performance in adhesively bonded connections
Sammanfattning : Birch (Betula spp.) is a hardwood species with a wide natural distribution on the Eurasian continent, especially in northern Europe. LÄS MER
