leaching from Asphalt
The use of recycled asphalt pavement (RAP) as road base material is an increasing trend in the road construction business.
... When subjected to rain water, these heavy metals and PAHs have the ability to leach out of the road base and
infiltrate into the water table, potentially impacting the quality of drinking water.

I suspect your contractor gets the asphalt millings far cheaper than gravel or any other product but I suspect he is not passing that saving on to you.

I would use asphalt millings. In fact I have done so, filling in a couple pot holes at the end of my driveway. My reasoning is they already exist and they are leaching somewhere already. Might as well be doing something useful since it's not like they are gonna shoot 'em into the sun if I don't use 'em. I am not growing food in my driveway so I am not worried about it too much but I sure wouldn't use grindings for my garden paths... I know that often you (or your contractor in this case) can get the grindings for free or next to it so that will save money for sure but rock is already cheap. I would definitely not make this decision until you get a quote for both. It's the delivery that you are gonna pay for either way.
Also, they last longer? Than rocks?

Any hole you have now will simply reform again if you keep filling them.
Also, somehow enforce a speed limit .
I have tried on mine and failed.
Speeding vehicles will trash a driveway.
Best equipment a grader and multi tyred roller.
If you put gravel over it then, the best tool may be a box grader.
Watch box grader
