Yeah.

Washboarding is actually caused by vehicles accelerating and braking. That's why it's more likely to occur near intersections, on hills, etc. The only way to get rid of it is to cut below the bottom of it.

What Jaden is referring to is known as a "Sandvick" blade mounted on the front of a road maintainer on the vee snowplow mounts. It's a vee blade with teeth to cut below the bottom of the Washboarding. Once the top several inches of surface are broken up, it can be bladed smooth again.

Next is a scarifier with coarser teeth, mounted the same way, for more severe cases.

The bottom line is, the only way to get rid of washboarding is to cut below the bottom of it and blade the surface smooth again. And, a lot of that depends on the skill level and work ethic of the machine operator. Our county has 16 precincts, with one machine and operator assigned to each precinct. And, each operator has his own skill level and work ethic, so some precincts have better roads than others. Some take great pride in the job they do, and others are "less dedicated", to be charitable. I ran across one machine, maybe 5-7 years old with a scarifier on the front. The scarifier still had the factory paint on it. In short, after all of the roads it had gone over, the scarifier had never been used.

The operator in the precinct where I live is great. We hired him away from the Nebraska Department of Roads. He said he was bored standing around all day at NDOR and wanted a job where he could keep busy.

Hope this info helps.
