Abstract Mechanically produced abrasion particles and resuspension processes are responsible for a significant part of the PM10 emissions of road traffic However specific differentiation between PM10 emissions due to abrasion and resuspension from road pavement is very difficult due to their similar elemental composition and highly correlated variation in time In this work Mobile Load Simulators were used to estimate PM10 emission factors for pavement abrasion and resuspension on different pavement types for light and heavy duty vehiclesFrom the experiments it was derived that particle emissions due to abrasion from pavements in good condition are quite low in the range of only a few mg km(-1) per vehicle if quantifiable at all Considerable abrasion emissions however can occur from damaged pavements Resuspension of deposited dust can cause high and extremely variable particle emissions depending strongly on the dirt load of the road surface Porous pavements seem to retain deposited dust better than dense pavements thus leading to lower emissions due to resuspension compared to pavements with a dense structure (e g asphalt concrete) Tyre wear seemed not to be a quantitatively significant source of PM10 emissions from road traffic.
