Actually Garak roads here are lucky to get 12 inches of packed sand or substrate an 3 inches of finished road surface.
27 inches is insanity.

I'm quite surprised. In Regina, they do a little more routinely, at least in the big, visible projects, since the amount of clay in the soil here is a little much, and they did an even deeper base for the highway in the valley.

I certainly haven't observed a lot of other highways in the province or roads in other cities, so it's certainly possible. Here, it would be a little problematic due to heaving. On Winnipeg St, a number of years ago, they went down a few feet and they still end up doing it almost every year it seems.

8th Avenue up here caused some trouble a number of years ago. They wanted to dig down there fairly deep, but they had just kept recapping in years past. The young city workers weren't aware there were streetcar tracks buried under all that pavement.

I spoke to a road engineer some years ago, and he said at least three feet should be done here due to the clay content. However, he said the amount of work and money that would drain would be a little much. He did indicate that the bus lanes were done with more caution than most other places.

I've got some pictures from the archives of the creation of the 401. It is impressive how much work went into the foundation of that road

That must have been quite the job. Here it's usually just paving on top of old pavement, with some being chewed down. I haven't observed much of the new construction, but I'm fairly certain a good portion is fairly shoddy. I noted how a couple streets here were definitely very deep, but some of the new areas have had less than a year of traffic and the roads are like roller coasters.

Hi,
OVERK1LL - These Pics look just like German Autobahn construction during the 1930s.......

We're still waiting to start in much of OZ - well here in QLD where I live

 

[Garak]

Definitely impressive!

Good thing you don't own a diesel engine then, I guess. You'd be changing your oil every 100 miles according to the above methodology.



Yeah, and since when is visual inspection the right way to determine an oil's status?

Good one. people on this site do everything but taste the oil to determine OCI's.

Nah, I can check my Na and Mg levels by taste
