مستخلص:	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. Mängden som icke-avgaspartiklar bidrar med till PM10 varierar med lägst nivåer på landsbygd och högst nivåer i vägnära miljöer. Avhandlingen har flertalet mål, där ett bredare mål är att undersöka det komplexa väg-ytadäcksystemet gällande vägslitage och dess inverkan på genererandet av slitagepartiklar och vägdamm, inklusive transporten och lagringen av vägdamm på vägytan. Avhandlingen syftar även att sätta in dessa aspekter i relation till andra lika komplexa funktionella parametrar som kommer av eller påverkas av vägyta-däckinteraktionen såsom bullergenerering, rullmotstånd och fiktion. Detta görs genom några mer specifika mål och begränsningar som beskrivs i avhandlingen. Avhandlingen har även det fundamentala syftet att agera som en start för att nå ett holistiskt helhetsgrepp för att förstå den funktionella prestandan som krävs för väg-ytadäckinteraktionen, vilket har genomförts i samarbete med Vieira och det som han publicerar i sin avhandling. Vägyta-däckinteraktionen utgörs av ett komplex kontaktsystem, som påverkas av både däckegenskaper och vägens egenskaper, dels ingående material och vägytans karaktär, samt omkringgivande miljö och eventuella mellanlager av till exempel vatten, slask, snö, is eller sand och grus med mera. Slitlagret, eller vägbeläggningen, har flera funktioner som beror på de ingående materialens egenskaper. Beläggningen måste motstå flertalet olika nedbrytningsprocesser, inklusive stensläpp, olika typer av deformation, olika typer av spr Particulate matter is a problem for human health, where several relationships between negative health effects and air pollution has been found, including, but not limited to, respiratory diseases, lung cancer and cardiovascular diseases. In countries where studded tyres are used, for example Sweden, Norway and Finland, and where traction sanding is used, particles from abrasion wear of pavements and crushing of traction sand contribute significantly to PM10. The thesis has several objectives, where a broader aim is to investigate the complex road surface and tyre system regarding abrasion wear of pavements and the impact on abrasion wear particles and road dust. The thesis also aims to put these aspects in relation to other, equally complex, aspects coming from or affected by the road surface and tyre interaction which include noise, rolling resistance and friction. This is done through some more specific objectives and limitations described in the thesis. The thesis also has the fundamental aim to act as a starting point to reach a more holistic approach to understand the functional performance of the road surface and tyre interaction which has been done in cooperation with Vieira and the results he publishes in his thesis. The road surface and tyre interaction consist of a complex contact system which is affected by both tyre properties and the road surface course properties, including both its inherent material properties and the road surface characteristics, as well as the surrounding environment and any interface consisting of for example water, slush, snow, ice or sand and so on. The surface wear course has several functions which is dependent on the inherent material properties. The wear course must resist several degradation processes, including chipping, different types of deformation, different types of cracking as well as abrasion wear due to studded tyres to mention some. The surface course construction and the traffic characteristics affect the particle
