Considerable attention has been focused on particulate matter (PM) produced from paved road and construction activities because of its adverse effects on potential air quality. PM10 is a typical air pollution source produced emitted from paved road. Effectiveness of street sweeping for controlling ambient PM10 was evaluated by TOPAS and determining silt load from active traffic streets. A modified regenerative-air vacuum sweeper and a washer were used in this study. The sweeper made a pass followed by the washer. The sweeping efficiencies（ηs）were obtained based on the experimental data of silt loading and PM10. When a vacuum sweeper and a washer, respectively, did a good job collecting or cleaning the visible fine particles on roads, the method of sweeping tested in this work was effective at removing the sources of the road dust particles. This paper concludes that street sweeping followed by washing was found to offer a measurable reduction in PM10 emission potentials.
