Sounds more like someone at the city government level selected the lowest bid contractor. You get what you pay for.
same with spacewalks.
So the Challenger and Citation owners sued the contractor........yes? You pay peanuts you get monkeys.
Cost me $2000 just last month to ripe out a replace a bad spot in my asphalt driveway, then recoat the entire top. Size of driveway was 20' by 50'n
Retired Air Force civil engineer here. I've got an awful lot of pavement experience on aircraft operating surfaces and still do pavement assessment all over the US. What most don't realize is that the single most important factor in aircraft pavement design isn't the overall weight of the aircraft, but rather the tire pressure. A Cessna Citation has a nose tire pressure of 120 psi. That is very hard on asphalt and is probably something the pavement designer didn't take into account when selecting the pavement mix.
