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.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Arent the majority of your freeways concrete?
Structure is concrete, road surface is asphalt.
For all freeways are all asphalt? Thats not correct Cali for a start has been moving to concrete.
Concrete is used for the top layer for higher load areas were budget and the foundations can support it as its more inflexible. Asphalt is used as its cheaper (initially, it will need renewing more often) and it will support more movement for the foundations and worse weather.
We (UK) had part of the M25 done in the same style, but it was shit as we cut the budget and its lots of small joined sections due to complexities of using larger slabs. The foundation has since moved about and the gaps get bigger.
