Sometimes in very hot weather here the highway surface will buckle upwards, making a ridge in the road.
Concrete buckles at 90 degrees? I’m no expert, but I do not believe the a 90 degree day made a steel and reinforced concrete bridge fall down. I’ll buy rust, faulty construction, bad materials and any number of reasons, but a hot day?
“Sometimes in very hot weather here the highway surface will buckle upwards, making a ridge in the road.”
Roads here, both tar and concrete buckle and blow up on a regular basis in the summer heat. Has a lot to do with how cold it gets here in the winter.
Expansion and contraction thing.....
Rain moving in, no warnings issued at this time despite newscasters saying otherwise.....
