How long to let residential concrete driveway sit before driving on?

Assuming it's 4 or 5 inch thick concrete, 7 days is reasonable.

We drive 18 wheelers on 6" 3500 psi paving with a good compressive strength test after 5 days.

This is a good conservative timeline. If you have batch reports from the mix you can get a better idea of when it should reach 75% of the design capacity.

Generally speaking, you will reach 35-40% strength after 3 days and around 70% at 7 days. So depending on the mix strength, that will tell you when you reach around 2,500k psi which is what you want for a vehicle load. You are 10 days out so unless you poured a light strength mix, you are good.

Some pretty smart sounding dudes in this thread….I am impressed!

My dad always said, you should wait 2 weeks before driving on a freshly poured concrete driveway.
