Particulate Emissions from Tire-Road Contact

TRCP (Tire-Road Contact Particles)

Particles resulting from tire/road interaction, including all particles (re)emitted at the rear of the wheel: wear particles resulting from abrasion of the tire and the road surface, the mixture of which forms TRWP (Tire-Road Wear Particles), plus contaminants present on the road surface and resuspended dust.

TRWP (Tire-Road Wear Particles)

Particles generated by wear on tire treads and road surfaces. They are produced mainly while driving, under the effect of friction and shear forces at the tire-road contact. TRWPs are a significant source of fine particle pollution (PM₁₀ and PM_2.5).

HVS (High Volume Sampler)

High-volume sampler used to collect and classify particles according to different size ranges, based on the inertial impaction technique where the most massive particles move away from the air stream...
