Hmm, that's interesting. Don't you guys generally use concrete for paving in the US? In building construction, you're supposed to give concrete like a month to fully harden, even though it already looks firm after a day or so.
For paving, they're likely using a hardening accelerator, so the timelines wouldn't be the same, but if building construction is anything to go by, it seems like you'd want to give it as much time as possible, not send cars on there while it's still hot. 🥴
