Key Takeaway: Water is a short-term, daily dust control solution for unpaved roads in humid places with nearby water sources. Gravel for Dust Control. Applying gravel on an unpaved road can reduce dust by creating a buffer between the road and vehicles. This helps prevent cars from kicking up dust particles from the road into the air.
