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?

Thank you for the answers and for putting up with my follow up questions. I’m learning a lot!

    Concrete is gravel, sand, cement, lyme, and water, mixed in various ratios.

    There’s a lot of variations and additives that can change how quickly it cures, often to speed it up or slow it down to account for weather (temperature and humidity play a huge part in how it cures), or to modify the pace of how it cures so you can keep building on it if you’re building vertically.

    It’s a simple concept that gets incredibly complicated very quickly.

    Big rocks, little rocks, cement, water.
