We all know that freeze thaw cycles cause immense damage to our roads, but just how much? All else being equal how much longer would a stretch of asphalt in Florida last than one in Maine?
In warm areas you have the tendency for asphalt to rut and deform. You see stuff like stop bars go wavy like it's silly putty.

Does that cancel out the effects of no freeze thaw cycles? Also, does rubberized asphalt, like they use in Arizona, help?

There are too many variables to give a simple answer. Other replies have cited some of them. Freeze/thaw cycles do damage, but are essentially irrelevant if you can prevent water infiltration, which is not impossible--it is just very difficult. You can also have binders that are more susceptible to stripping and other forms of chemical degradation in heat.
