=======Some of the old runways that i have landed on have ruts where years
of  landing have somewhat pounded down the surface...these ruts hold water
and cause severe hydroplaning problems on high speed landings.  Cost me at
least one set of skins on an F-4.  Most of the runways do seem to be
somewhat higher in the middle where the water will run of to each side.
There are also the ones that have grooves cut into the landing surface and
those that have porous asphalt surface that lets the water drain off of the
surface.  Interestingly, the water comes back to the top when it freezes,
giving a form of black ice...not nice.

Somehow we need some good all weather surfaces...Heated with drainage?
