In Illinois most of the wear on the asphalt surface occurs via ice and snow causing potholes. This happens over time regardless of heavy traffic.

If they used crumb rubber asphalt hybrid, it wouldn't be a problem, but the fucking unions lobbied and blocked it. I cant find that source but recall it was a story on the news years ago in Chicago. Unions said if that was used, they'd be out of jobs becuase roads would last longer... yeah.

While this may be true, big rigs and other ultra-heavy vehicles cause a disproportionate amount of wear as well.

The source for that data is a bicycling blog in Colorado which no longer exists. Without verifiable data, I'd ignore it.

Trucking and weather damage both contribute, and each exacerbates the other. On roads with lighter traffic, patches last longer, too.
