Why does anyone use fragile asphalt (20 years) for busy roads when engineered concrete lasts 50 or more? Because the better option costs more.

This was a big point of contention when a local town announced it was replacing the failing asphalt on the section with the most traffic with slabs of concrete. [0] People complained about the price. Meanwhile, over a decade on, nearby asphalt laid with the same renewal project is already cracking while the busy main thoroughfare remains undisrupted by road work.

It's hard to persuade people that long-term investment is worthwhile.
