Speed Wastes Salt, the Proof is in the Numbers (Individual)

We all know that when rock salt is spread from a truck, it "bounces and scatters" before settling on the pavement. For decades, it was assumed that pre-wetting the salt before spreading it was the best way to minimize bounce and scatter. But pre-wetting is actually only a small part of the solution.

In the summers of 2012 and 2013, the Michigan Department of Transportation’s Operations Field Services Division organized two hands-on research studies to determine exactly how prewetting, truck speed, and equipment type affect salt bounce and scatter.

This short presentation summarizes their findings. It's a perfect conversation-starter for an entire winter maintenance crew and a great first step toward more efficient and effective winter maintenance practices.
