Money_Pits Posted June 16, 2020 Share Posted June 16, 2020 Here in Missouri, I've seen that happen from heat buckling, but never quite that high. Link to comment Share on other sites More sharing options...
Pete M Posted June 16, 2020 Author Share Posted June 16, 2020 I'm used to the freeze/thaw cycle causing that in michigan on some of the more poorly built roads, but I've never seen anything even close to that high. Link to comment Share on other sites More sharing options...
Blue XJ Posted June 16, 2020 Share Posted June 16, 2020 That happened on I-69 up here a few years back, launched a few cars into the air pretty good! Link to comment Share on other sites More sharing options...

Dzimm Posted June 16, 2020 Share Posted June 16, 2020 Yeah that's heat buckling. Definitely quite tall. Must have been a hell of a ride for whoever is in the ditch up there. Link to comment Share on other sites More sharing options...
gogmorgo Posted June 16, 2020 Share Posted June 16, 2020 I’ve seen lake ice do it, and I’ve seen similar results with frost heaves in winter, but never on a concrete slab highway. That’s gnarly. Link to comment Share on other sites More sharing options...
derf Posted June 16, 2020 Share Posted June 16, 2020 Heat buckling that bad usually happens because of shortcuts taken or mistakes made during construction. It's a known phenomenon and dealing with it is pretty straightforward. You have to put enough room for expansion in the road bed. If you don't, you get buckling like that.

gogmorgo Posted June 17, 2020 Share Posted June 17, 2020 Would dust, sand, etc., getting into expansion joints contribute? Link to comment Share on other sites More sharing options...

Anything in the expansion joint can contribute. I used to be part of a highway maintenance crew and we'd see these come up every so often. Rigid (Concrete) pavements are the only ones that have the issue. Just like all materials, concrete expands and contracts in the heat. A prior repair adjacent to this section of pavement, the sun hitting it at just the right angle, ambient temps not cooling down enough during the prior evening, anything really that changes around it from year to year can contribute to the buckle. I used to know where a smaller one was on my daily commute during those years working on the roads 15 years ago and I would hit it at speed on my way home each night.

gogmorgo Posted June 18, 2020 Share Posted June 18, 2020 I actually work for a highway maintenance dept, which is why I’m curious. We don’t have any concrete highways out here, though. I have this feeling they wouldn’t hold up too well to the freeze-thaw cycles and road salt. Link to comment Share on other sites More sharing options...
