Is it absolutely necessary to mill prior to a bituminous surface course overlay? Are there other reliable methods to ensure long-term viability of the overlay aside from milling?

For example, you have an old road which was paved over several times without change of curb. The curb became from 12 in tall to 2 in tall. Another paving will make curb invisible, so you mill to allow more top to be put down.
Milling, specifically, for a better binding action is a waste of money (unless you really wanna do it), most of the time it is not done. Besides, you will still need to put tack coat on a milled surface before top course.
I mean, a price of milling is about $2/SY these days. Do you want to charge/pay $12000 for 0.5 mile stretch of 2-lane road if it's not worth it?!
No peeling, unless it is poorly paved (tack coat)
