How long before you can use the driveway once it has been paved?
Keep vehicles off of it for a week. Heavy trucks for at least a month. For at least a year don't turn your front tires with out the vehicle in motion. Ya wanna backfill the edges before you drive anything on it. You can walk on it the next day.
Give the harding at least two weeks.
24 hours but take your shoes off when u go in the bottom will b black
24 hours but just to make sure take a garden hose to help cool it down and harden.
Give it a week, time to properly set, but can be used after 24 hours , depend on the weight of the vehicle. Concrete usually take 3 to 4 weeks to fully set.
