Why is it so expensive and is there an alternative out there that won’t break so easily especially in the winter? My state is spending like a billion dollars a year on roads that they’ll probably have to fix in 5 years, it really seems like a huge waste of money.
Good Public transportation would fix a lot of these costs I know but what other road materials/solutions are out there?
They are actually using asphalt under the balast at least in some European countries. Also, some HSL have the balast replaced by a concrete slab. It’s also the case for tunnels.
The new metro lines are often using concrete slab as well. Trams actually too.
