The above was: Repair damaged areas first, then two passes of two inch asphalt, freshly graded shoulders with fresh gravel cover, center lane stripes and border* line.

 I may have mentioned this before, but: A few years ago I stopped at the County Engineer's booth at our huge county fair. I wanted to learn how, over the years, the little rural roads went from gravel to "paved" - and I put that in quotes because they are often in bad shape, for at least a couple reasons. I was particularly curious about the base or foundation of the pavement, which I understand to be very important.
 The two young engineers looked at each other with raised eyebrows and told the tale. Decades ago whoever was County Engineer decided to make his name (and win reelection) by paving the maximum possible number of gravel roads. He had it done by doing essentially no preparation. They were scraped level and covered with asphalt. Supposedly, layer after layer has been paved on top ever since.
 Admittedly, I'm not a Civil Engineer. But I wonder what base preparation your local company did before laying down the asphalt. I do know that state or municipal pavement is supposed to be done to high standards. Civil Engineering students I knew got summer internships in which they took core samples and tested them to be sure the paving contractors were doing things according to contract specs.
 

I don't know but it's built like  Roman road, raised above surrounding fields with broad ditches  on both sides and culverts here and there. And dead straight, that is, planned as opposed to the curvy meandering ones which I assume started as cow paths.
