Many roads arent ready for climate change


Most road surfaces in the. Us look pretty similar. You might think they're all the same but they're not transportation. Engineers design asphalt roads specifically for the local climate considering temperature precipitation and humidity. The material that we use in arizona will be different than what we use. In minnesota the material arizona will be stiffer. it'll be able to withstand the high temperatures much better whereas the material in minnesota will be a bit more flexible and accommodate the cold weather much better that scene underwood of north carolina state university. He says that choosing materials engineers rely on climate data but that data is often decades old so as the climate warms engineers may unintentionally make poor choices underwood. Research suggests that about a third of the roads built in the us in the last twenty years were not made out of appropriate materials so some may wear out faster than expected instead of a pavement lasting twenty years. Maybe it only lasts fifteen years. Maybe it has more maintenance that means unexpected costs for communities. So when designing roads underwood's says it's important to account for the changing climate
