Wet Road Agglomerate
Wet road agglomerates are part of the road spray that is generated by traffic driving on wet roads.
The particles are a mixture of smaller particles containing road wear and particles that have settled
on the road. This sample contain a number of flyash particles (glassy spheres).

Wet road agglomerates are particle clusters that include tire wear, road debris, pollens, and other particles commonly
found on the surface of roads. The road debris may be from asphalt or cement roads. These particles are the road spray
residues formed when the road is wet and the normal road debris is agglomerated rather than free floating.
Significance in the Environment:
These particles indicate an essentially direct route for air to the indoor environment. Typically it's an open window or
proximity to an exterior door.
