Firstly, this is how you should make your airbase:

with using this texture, don't see a reason to make another texture for yours?
Next your texture is most likely super shiny as you haven't made a spec map for the texture, which goes in the alpha channel Firstly, this is how you should make your airbase:

You're normal then doesn't at all work because it's firstly all over the place, it's like it was poured and then never smoothed over leaving a seriously uneven surface like the surface of the moon...
Finally your normal is the wrong way round for BF2, so your cracks are popping out and your slabs are sinking inwards, where they should be the other way around. While it's the correct way around for most games/engines, BF2 has the green channel flipped which IMO, makes more sense since then its a lot easier to see how the normal works just looking at the texture and here is yours flipped quickly, and now you can probably see the unevennesses more clearly:
In contrast here is the normal for my airfield texture (which is only used on "The Falklands" since there the airbases are totally built into the terrain, for making an airbase in the proper method, you can't use a normal) and you can see, it's very smooth in comparison, only with the cracks between the slabs and the tiny bumps in the concrete itself.
Finally as for why your UV is messed up, hard to say just from looking at the shot but could be exceeded tiling of the texture over 16 tiles, or could just be bad UVing
