What runway materials reduce skidding in wet conditions?
This question has kept industry awake at night for ages now. A good start is here. 

TL; DR: In addition to grooving, some runways (e.g. London City) apply a special surface material that is called a Porous Friction Course.


  An alternative to grooving as a means of facilitating surface water dispersal is the laying of a Porous Friction Course (PFC) which allows water to pass vertically through the surface layer and then move horizontally clear of the runway beneath, but essentially parallel to the surface. 


The trouble with all that is that if you test it, build it and then calculate performance taking credit for it, if it doesn’t work for real for whatever unknown unknown, you are likely to find out by having to remove an aircraft from the Thames river which is kind of frowned upon by most. You want to be a bit conservative with runway friction.
