Although fresh paved roads are nice it is always painful to see years of traverse sacrificed to the road grinders!:-D 
This is one reason I very rarely set a control point in AC pavement. There's plenty of concrete curbing there, which is where I would have set my traverse points. Concrete disappears too, but not nearly as often as AC. It also tends to be farther away from road traffic.
I feel your pain.

Then when a snowplow driver takes it upon himself to move your curb a little bit you are SOL with your POL.
Not too many snowplows in Yolo County although Route 16 has "Chains Required" signs so maybe it snows in the canyon north of the Capay Valley once every 20 years.
Here, most of them are paved over rather than ground out. Just take a metal detector, get over the spot....note it as signal found...and go back to work....
How soon we forget Mr. Geodesist, Bill Strange.
Your traverse isn't gone, it is simply monumented in another fashion. 🙂
