Curious...when asphalt contractors come in to put down a driveway must they kill the green grassy/broadleaf plant life before asphalting the area....because if they dont it will just weaken the asphalt overtime?

Or is this optional?

I am a 17 year civil engineer with many miles of street design and construction.
1. Spray ALL weeds with a heavy duty weed killer 4 days prior to paving.
2. If rain withn 48 hours of weed killer application, reapply.
3. Gravel is not always necessary if AC is thick enough.
A driveway needs only a 4" thich asphalt over compacted dirt.
4. Make sure contractor levels and compacts the surface thourougly.
5. Spray a layer of tack coat, this makes the AC stick much better thna without.
6. Roll well after applying AC.

I think most asphalt pavers for driveways are liars. All the ones that come by my house say" we have some left over from a big job & will make a deal".
I've seen some of their work. They pave over anything that won't move out of the way.

The concrete will require less maintenance. The asphalt needs sealing and such every year or so. The concrete is more prone to cracks and can become severely cracked if the small cracks aren't filled properly. I have had both and still believe a concrete driveway if properly cared for will last the longest.

One would hope that any decent contractor would grade the area, probably below ground level; add crushed lime rock, or other appropriate base, then blacktop.

It's doubtful they would do any other form of foliage barrier.

It might also depend, in part; on your ability to choose the height above ground level you want the driveway to be.

If they dont kill the broadleaf stuff it will just grow back up thru the asphalt over time,

no, the area must be properly prepped with a layer of gravel mix first..

they have to dig a foundation of some kind or scrape it, and that removes any plant life and seeds...
