Ever notice how crappy todays concrete is compared to old stuff?
What are you saying? That old concrete is better than new concrete? The Roman's invented concrete, both terrestrial concrete and underwater concrete. The Roman army built several bridges across the Rhine in the time of Marcus Aurelius, most of which were used for heavy foot traffic, cart traffic, and finally vehicle traffic. The last one was closed down in the 1970's, 1800 years after it'd been constructed. And of course there's the Pantheon. Roman concrete and its many applications by Roman engineers was so good, it still mystifies engineers to this day.
I'm saying the mix they use today is nowhere near as good as used when freeways were laid down, thus they need more fixing which is good for union workers not so good for taxpayers.
