    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.

  4. 3. Non-Exhaust PM10 and Road Dust

    Författare :Joacim Lundberg; Sigurdur Erlingsson; Mats Gustafsson; Sara Janhäll; Göran Blomqvist; Brynhild Snilsberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road Dust; Abrasion Wear; Road Surface Macro Texture; Mean Profile Depth; Mean Texture Depth; Emissions; Abrasion Wear Model; NORTRIP; PM10; Air Quality; Particles; Vägdamm; Vägslitage; Dubbslitage; Textur; Emissioner; Slitagemodell; NORTRIP; PM10; Partiklar; Luftkvalitet; Byggvetenskap; Civil and Architectural Engineering; 15 Road: Environment;

    Sammanfattning : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. LÄS MER

  5. 4. Tyre/road interaction : A holistic approach to the functional requirements of road surfaces regarding noise and rolling resistance

    Författare :Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Tony Parry; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; surface; noise; rolling resistance; tyre; mitigation; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Building Materials; Byggnadsmaterial;

    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

  7. 5. Tyre-road Interaction: a holistic approach to noise and rolling resistance

    Författare :Tiago Vieira; Sigurdur Erlingsson; Ulf Sandberg; Anders Genell; Hans Jonasson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement; surface; texture; noise; rolling resistance; tyre; Vägbeläggning; vägyta; textur; buller; rullmotstånd; däck; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : 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.
