Asphalt and concrete are the main two. Check out this page on Wikipedia for a lot of good information: http://en.wikipedia.org/wiki/Road_surface
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
how hard the surfaces push to gether the types of surfaces involved
The difference between trail and road surface for running is that trail is usually dirt roads as opposed to tarred (tarmac) surfaces associated with road surfaces.
Yes.
The Apparatus fixed to the wheels of a car to lessen the effects of rough road surfaces??? Answer: steering wheel
Earth's surfaces are affected by many types of movements and changes. The main effect on earth surfaces is caused by the movement of plate tectonics below the surface of the earth.
Any solid object has a surface, and there are almost as many types of surfaces as there are classifications of objects. Surfaces can be smooth, granular, abrasive, glossy, flat, curved, and in any shape or texture imaginable.

The force with which both surfaces are touching and the types of surfaces involved
Dark, rough, and/or porous surfaces absorb the most heat (ex. Asphalt)
If both of the surfaces on which friction is to be created are very rough, the friction will be more. The more rough the surfaces more friction we have.
This would be essentially impossible; each state has widely varying road surfaces within it, and road surfaces do not necessarily vary from state to state. Whether or not they can, however, is mostly irrelevant since it is much simpler for them to use their GPS which will give them information much more specific than what state they are over.
