Concrete hardens to 600PSI (Minimum) after 24 hours. This means that 5 three grown men could all stand on a pogo stick (if that were possible) who's base covers 1 square inch without harming the concrete. You walking with shoes on exert about 10 PSI, well below anything that could damage the new pour. Just don't drag anything heavy across it, or place anything with sharp points on it.

There are several things you need to do to maintain your driveway and keep it from cracking. First, remove any vegetation that is close to your driveway. Trees and bushes may send roots out that will eventually grow underneath the concrete and cause it to crack. You should also edge your driveway. Make sure your water disposal systems are kept in good working order. Water flowing under your concrete can cause freezing in the winter. Finally, use a concrete water sealant.
The minimum compressive strength required for a concrete driveway is typically around 3,000 to 4,000 psi (pounds per square inch). This strength ensures the driveway can withstand the weight of vehicles and resist cracking over time. Additionally, the thickness of the concrete should be at least 4 inches for standard residential driveways to provide adequate support.
