Non-exhaust particles in Nordic countries : a collection of updated knowledge on short-term mitigation for road dust, factors affecting production, and strategies to handle different kinds of non-exhaust particles
Publication details: [Norden] : Nordiskt vägforum. NVF, 2024Description: 33 sSubject(s): Online resources: Abstract: This report addresses the significant impact of road traffic on local air pollution, particularly in densely populated areas, attributing it to mechanical wear of road surfaces, notably from studded tyres prevalent in Nordic countries during winter. Short-term mitigation measures on roads, such as road cleaning and dust binding, are highlighted as effective methods to reduce airborne particulate matter. Road cleaning involves the removal of dust from road surfaces and adjacent areas using various equipment and methods. Timing and planning of road cleaning operations are crucial. Dust binding operations aim to bind road dust to the surface before it becomes airborne, using chemicals. Various factors are affecting the effectiveness of dust binding operations, like street surface conditions, the dust load, weather conditions, type and concentration of chemical solution, and application method. Although dust binding is effective, it also poses environmental challenges. A review of different environmental and corrosion effects and price of different dust binding chemicals are given. Methods for managing unpaved roads are summarized. Other short-term actions discussed include reduced speed limits, traction sanding, even/odd numbered license plate restrictions, and temporary bans on studded tyres. The report discusses strategies to address non-exhaust particles generated by road traffic, focusing on factors influencing the production of these particles. Key factors affecting pavement wear include traffic volume, types of tyres (studded vs. non-studded), pavement material, driving speed, climate, winter maintenance practices, road design, and driving patterns.This report addresses the significant impact of road traffic on local air pollution, particularly in densely populated areas, attributing it to mechanical wear of road surfaces, notably from studded tyres prevalent in Nordic countries during winter.
