Both tarmac and concrete trap heat as they have a thin film of stagnant hot air over them.

Our highway surfaces are mainly and increasingly paved with a kind of pervious concrete called ZOAB for Zeer Open Asfaltbeton (very open asphalt concrete).
The main goal is to prevent spray and standing water during rain, and that works really nice like this morning; medium rain, no spray, 100% visibility, wipers on short interval.
Over bridges there are small sections of 'regular' tarmac; so the cars throw up spray there and my auto wipers flick into high gear.

The very open structure prevents the air film to form like it does on regular road surfaces; it vents itself so it does not get as hot and the open structure creates small sunny and shaded areas, further increasing convection.
As a bonus, it reflects less than any other road surface.

Such a pity that it is relatively expensive and not very resilient.
