RE: Pavement jointing
Stated simply, you should never "dead head" a joint. Always assume that a crack will form in a joint and that the crack will propigate beyond the joint where you stop it.

RE: Pavement jointing
If you are doing asphalt pavement, then vertical joints should be offset from the vertical joint in the lift below. I see no reason to line up asphalt joints from one street to another or at cold joints.
If you are doing an asphalt overlay on concrete, then no reason to line up the joints, same thing with a concrete overlay on asphalt.
