Is rain good for new asphalt driveway?
When rain comes into contact with fresh asphalt, it causes the oil to rise to the surface which can affect the curing time and the finished product. If asphalt is paved while it’s raining, it can reduce the overall quality of the asphalt. Rain also jeopardizes the stability of the subsoil.
