In northern latitudes mineral dust is
formed when cars use studded tyres and roads are
sanded to obtain more traction on the icy surfaces.
Anti-skid and asphalt aggregates with different
textural, mineralogical and mechanical properties
were tested with an indoor road simulator fitted with
studded and friction tyres. The particle size
distribution and proportions of dust from
pavement and anti-skid aggregate were analyzed
using SEM-EDX. The wear on the road pavement
depends on the properties of the anti-skid and
asphalt aggregate (particle size distribution,
mechanical/physical and textural properties). Antiskid
aggregates, which contain mainly hard minerals
(e.g. feldspars and quartz) and which have a low
resistance to fragmentation, should be used with
caution as they may break more easily into smaller
particles and are likely to wear the pavement. By
using high-quality anti-skid aggregates it is possible
to reduce the amount of urban dust.
