Material models in a mess after importing to Unity 3d

Hi, I'm new to Unity 3d Project. I have a problem regarding importing 3d Models into Unity 3d Scene

When I import my street model into the scene, the materials and the textures are in a mess. I use multi sub-object material in 3ds max. Here is current scene in my 3ds max

After imported to unity, I have got this materials and texture in a mess

Some streets texture are not in correct direction. This only happens with materials that I have been set UVW to 0 0 90 deg
