I think I saw a youtube video once where the guys claimed the only way to prevent washboards from forming in the first place is to keep all vehicle speeds under ~3 mph. Anything above that and they'll form eventually. I think the same video said that you can lower your tire pressure so that the tire contact surface spans the width of the washboard and that makes them barely perceptible. I don't know about the feasibility of that, but lowering tire pressure does make them much more tolerable.
