Would it be so bad to use concrete instead? Sure the up front cost is higher, but it has a higher albedo and lasts longer, especially since Phoenix doesn't have snowplows tearing up the streets.
The total cost of ownership differences between asphalt and concrete roads is astronomical.
A single pothole in concrete is a very invasive fix with significant amount of debris, but asphalt can be almost infinitely recycled.
Replacing asphalt means eating up the debris and putting it right back in the ground. Replacing concrete means toting truck loads of the stuff _somewhere else_ to sit

Road concrete gets crushed and used as road base.
Not the exact, perfect reuse of Asphalt but it does end up used as fill.
