I also grew up in Iowa, and the difference between the gravel roads I took to get to my friends houses there, and the gravel roads we have here in AZ is night and day.
About a decade ago, I remember reading about a trial application near me for an unpaved road hardening agent called pavezyme, which I also believe was trialed not long ago in AZ.
Do you know if any in your area might have been a part of that, and if so, how it worked out?
An adjustment in the allocation of funds would allow counties to bring more road graders and operators online. Right now I believe they simply dont have the capacity to do proper maintenance on all of the level A roads on a frequent enough basis. This might also allow for the conversion of some state highway routes and level B roads to level A roads.
