Cycling in Waterloo Region

[tomh009]

I expect that the ground does not freeze in the Netherlands.

The depth of the freezing is clearly different but we do get frost on the ground some days.

But I’d never heard that it is about frost heaving in winter. Like, that’s usually something that affects subsurface structures mostly. The leaving of asphalt I’ve always been told was about letting the first layer settle and compress under loads before doing the final lift.

Frost on the pavement is not a problem.

Frozen ground absolutely can cause unevenness in the pavement. Not terrible in SW Ontario, but still there, depending on the winter and the location. Not paving the final coat until the following summer is a very logical thing to reduce the risk of frost damage to new pavement.
