We build beautiful roads and bridges in other countries, just not our own.
In our 50 States road contracts go out to the lowest bidder who has to use the cheapest asphalt, the quickest methods and the lowest paid workers to get the contract. Roads fall apart as soon as they are built.
In Europe they use high-grade asphalt with rubber bits to keep the pavement from cracking and falling apart, they do not hire the cheapest bidder. Their roads look like Main Street Disneyland.
Ours are terrible. Our pavement ends at the white line, pavement needs to extend wider than the road as water damage occurs because there lacks margins. Many many problems
Road surfaces have a design life of somewhere around 20 years depending on materials and design criteria. Concrete lasts longer than asphalt.
In my opinion, asset management rather than a builders abilities is the bigger issue. In a perfect world, there are minimum standards (eg, asphalt mix design) that are included in contract specs, and qualified (hopefully) inspectors onsite to make sure that the materials and methods used actually meet those standards.
If infrastructure managers have no idea about the life of the different parts of their systems, then they may get caught with their pants down when the road fails, the bridge falls down, the water main breaks or runs out of capacity, and on and on.... If money is not set aside, and planning is not done to ensure a continuous replacement program, big trouble is sure to follow.
I have been over the bridge at Lake Charles, and later heard that it's condition was not far above condemn status. Scared the **** out of me........
Good asset management needs good funding, but unfortunately, the bean counters and politicians have different priorities because they don't understand the needs required to keep the real world running smoothly.
My opinion of course.
