For any newly paved driveway, it is important to wait at least 3 days before you drive on it. If the temperature outside is 20Â°C or more, it would be advisable to wait for a longer period of time.

You should try to stay away from the edges of the fresh concrete because the concrete in this area is weaker. In one month, the fresh concrete will have developed the proper strength and hardness.
