They apply calcium chloride solution as a dust control agent. CaCl2, AKA “cackle 2”

I'm not sure they compact very many roads around here (CO). I have lived, or spent time in, rural parts of four states (MN, IA, OH and CO) and I have never seen an unpaved road compacted. They get graded once a year perhaps to remove the wash boards, and some have a coating of something applied to keep the dust down.
