Cycling in Waterloo Region

If you put on the top layer right as soon as the binding layer has cooled and hardened (3-4 days) it would just settle right along with the binding layer and your street, driveway, or parking lot would end up uneven. Plus, the dual-layer construction like that also helps it resist frost heave better.

This is the story I’ve heard for years from engineers. All I know for sure at this point is that the Netherlands does not do this. When a road is re-opened it is opened with the final asphalt coat. Maybe it’s a weather thing, or a traffic thing, or maybe the story about settling is just BS, who knows.

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