July 18, 20223 yr I recall there was some tarmac melting last summer. Gritters are out on roads aparently, dumping grit on the soft stuff. I suppose in very hot climates abroad they opt for concrete.

July 19, 20223 yr I live in a very hot climate. I also live on a corner. My front street is a residential street and the side street is a main thoroughfare. Both are asphalt. I've never heard of them softening. We got up to 40C this afternoon and traffic was moving normally. I never heard of gritters. What do you Britishers pave your roads with? Noel The tires are worn. The shocks are shot. The steering is wobbly. But the engine still runs fine.

Noel Air temp can be at high 20's but because the asphalt absorbs and retains heat it can be at high 40's. It softens at 50. Polymers are added to asphalt in hot climates to significantly raise melting point. They've done that in some locations in the UK. Probably applies to your roads. Lorry gritters are normally used in the UK winter to spread grit and salt on the road to combat ice. Edited July 19, 20223 yr by martin-w

In Toronto, the temperature can reach the low to mid 30s and the only problem we have is in bus bays ( bus lay-bys) where ridges are formed called "knuckles". I checked a few airports in hot climates and found Dubai, Riyadh and Nairobi have asphalt runways but Las Vegas has concrete. Edited July 19, 20223 yr by dmwalker Dugald Walker

Yes, I looked it up. https://www.bbc.com/news/magazine-23315384 Which is why our roads, and my street, cracks in very cold weather and the cracks are filled with tar in the spring. My street has quite a few such tar filled cracks. BTW...we are forecast to have a high today of 42.8C (109F) Noel Edited July 19, 20223 yr by birdguy The tires are worn. The shocks are shot.

There are ways of laying track to compensate for expansion and contraction. Check out the third picture in the link below that explains CWR. https://worldwiderails.com/how-do-railroads-deal-with-thermal-expansion/ Noel The tires are worn. The shocks are shot.

July 19, 20223 yr 1 hour ago, birdguy said: There are ways of laying track to compensate for expansion and contraction. Because such high temps used to be a less frequent, less severe issue, our tracks weren't laid that way. Same scenario as our roads, in that why would you lay tarmac with fancy polymers to prevent melting when its a very rare occurrence. Trouble is, that's no longer the case anymore. Clearly changes will be required.
