Hello,
What is the maximum and the minimum temperature on the surface of the runway in the busy airports? If you know any study have been carried out about this, any published paper or article that can be useful.
Many thanks
Not an expert on this, but try this link.

I can imagine that some airports offer such information online equal to webcams.
There must be some guidelines/standards (FAA? ICAO?) for construction and operation of airports – sorry, I don’t know them. Depending on the surface of a runway I would assume that there are different limits for the surface temperature. Asphalt/bitumen will soften at certain temperatures. I guess that cement won’t.

All pavement surfaces heat and cool subject to thermal loading and surface material properties. Runways will follow the same thermodynamic rules and principles as roads. Asphalt is black to it absorbs heat and gets 'soft'. Concrete is light, so absorbs less heat and does not softened, as cement is not temperature dependent, like bitumen/asphalt is.
There are established models for estimating pavement temperature with depth, which are calibrated to local conditions based on real pavement measurements over time. The USA SHRP program extensively examined this for the introduction of the PG binder system. Computer program for temperature estimation at the first link below.
Also, good work applying this model to South Africa by Denneman at the second link below. And a FHWA report at the last link below.
In the end, the answer is 'location' dependent. I have measured, in Australia, surfaces from 0C to 78C. The change between high and low reduces with depth. Most people accept there is a relatively constant temperature below 150 mm from the surface.
Hope this helps.
Cheers, Greg
