The ugly secret is that highway repair companies are often rotten, and they lobby state legislatures hard to keep repairs using cheap materials that only last a few years. They will fight to the death to prevent quality road repairs, because it would put them out of business.
Many years ago, Phillips Petroleum created what amounted to Kevlar road bed. When laid down before the asphalt, the roadway would last much longer. But road repair companies bitterly fought it, and even had it outlawed in several states.
Another issue is paved roads that don’t need to be paved.
Where I used to live the dirt roads were all paved to support trucks building oil infrastructure. 20 years later the heavy trucks are gone and those roads are still maintained as paved roads despite only seeing 10 or 15 cars per day.
I live on a dirt street and its just fine.
That wouldn’t surprise me one bit.
Pork has a pernicious effect on many things.
