There are many variables linked to the destruction of our Michigan Roads, These issues are mostly in metropolis areas, but more so in the Metro Detroit area.
In the 1970's Michigan Legislation increased the lode weight of trucking transportation.
There isn't any set guidelines on the quality of materials for paving new roads.
Newly poured concrete does not last as long as it used to. perhaps regulations in the concrete recipe should be followed?
Many suggest salting our roads causes problems, but look at how long the Davison freeway lasted, it was one of the first paved highways in MI.
Concrete paving has a higher price tag compared to asphalt paving.
Winter conditions add to the equation as well!
Water beneath the asphalt freezes and expands creating these potholes.
It seems this system is set up for continued employment of road construction workers.
