Driveway replacement question

Errrr,
I'm not a road expert - but from the contractors I've discussed with, the road base is usually aggregate (rock).
I don't know if sand will work. (seriously, I have no idea)

Depending on where you live, and the soil types you have - you can always contact your local city roads department. I've found the city engineers are usually very helpful and easy to talk to.

I'm no road expert either, but maybe aggregate is less expensive and easier to "apply" than sand? I do know that if one doesn't want something to settle, put sand in first and pack it.

Dang we use 10" concrete often for interstates lol.

Back when I was driving a few trips back and forth to commiefornia they were replacing I-40 before or after (don't remember which) Amarillo. I swear that it looked like the new pavement was all of 18" thick or close and had serious steel rebar in it in copious amounts. It was big s***. Seriously stout! :ooh2:

Never seen it done like that in Oklahoma.

I know some road builders use fly ash from coal burner power plants to mix into the soil on road beds to stabilize it before adding base.
When I worked at Sooner Power plant we had trucks transporting that ash out of the plant 24/7, 365. A truck about every two hours. Some were headed to concrete plants where it was used as an additive in the concrete mix.

yep, fly ash or lime, depending on if the soil is clay or more sandy. every road I ever designed, the pavement engineer would always tell us to use on of these sub base treatments and at what percentage.

Never seen 18" in OK but its common to have 10" concrete on top of 4" asphalt base for full depth reconstruction.
Airports are typically around 24" thick if they are built for large planes to use.
