Thermal image of a road that was just repaved

I could feel the heat coming off it when I stood next to the repaved section. They didn't repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.
Even with accelerators it still needs a few days (usually about a week) to harden to 80% strength, and it will never be quite as strong as it would be without an accelerator.
I think that’s part of the reason we don’t use concrete pavement more often. It certainly lasts a lot longer, but laying it is way more time consuming. Asphalt is ready to go within a day, just needs to cool off.
