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.
