I'm still not entirely sure what you want to do, but I'll take a stab.
It is reasonably easy to customise your own runway textures, but this is a global change -- that is, you can change the asphalt runway textures, for instance, but this will change every asphalt runway in the world.
I suspect, though, that you want to change one specific runway and one airport? This is trickier. The only way I know uses GMAX and the FS2002 gamepack.
