Why Portland’s roads exploded during the heat wave

The video discusses the impact of unprecedented heat on roads in the Pacific Northwest, particularly in Portland, Oregon. It explains how concrete roads, designed with gaps for normal temperature expansion, failed under extreme heat, causing buckling and breaking. Asphalt roads also suffered, becoming soft and deformed under heavy traffic. The video highlights the need for road designs that can withstand extreme weather conditions.

Why were Oregon's roadways not designed to survive extreme heat?

Describe the process that leads to road buckling in high temperatures.
