Since asphalt needs time to harden and cure, usually 6-12 months, your parking lot or driveway will remain soft and pliable until then. You may walk on the new pavement immediately, but keep automobile traffic off of it for at least 3 full days and longer in hotter temperatures.
How long does it take for street asphalt to dry?
Asphalt takes six to twelve months to fully cure, and remains a little more susceptible to damage for that time. However, it takes 48 to 72 hours to “dry” enough for foot and vehicle traffic. This is for new asphalt. Resurfaced asphalt can be dry in as soon as a few hours.
What happens if it rains on fresh asphalt?
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.
How long does asphalt need to dry before rain?

Does asphalt cure in cold weather?
During installation, cold temperatures can prevent asphalt from properly binding which causes raveling. On the opposite end of the spectrum, extreme heat is an enemy of freshly laid asphalt too. Extreme heat can cause new asphalt to melt, slough, bruise and won’t allow asphalt to properly cure.
Does rain cure asphalt?
Does rain help asphalt cure? The rain does not help cure asphalt. Asphalt cannot be installed during the rainy season. This is because asphalt mixtures contain oil and as it gets wet, the oil reacts with the rain which affects not only the curing time but also the durability and quality of the asphalt.
Why do you water new asphalt?
When the temperature is high, the asphalt will become more pliable and will scar easily if you drive over it. Watering the new asphalt is a way to harden the asphalt again in hot weather so it is usable.
How soon after asphalt is laid should it be sealed?

How long does a driveway take to dry?

What temperature does asphalt cure?
Asphalt starts to cure once it cools, typically at about 220 degrees Fahrenheit; once it reaches 185 degrees, asphalt becomes too stiff and dense for proper compaction.
What is the lowest temperature to lay asphalt?
During initial application, the asphalt should still be at least 220 to 290-degrees Fahrenheit. If the asphalt dips below approximately 185-degrees Fahrenheit before compaction is complete, its consistency stiffens up too much to finish the job properly.
At what temperature does asphalt soften?
According to various sources, including Yahoo.com, on a 108 degree day the asphalt surface can become as hot as 160 degrees. By the way human skin can begin to seriously burn at 140, enough heat to cause injury. With pavement anywhere from 140-160 it will begin to get soft.

How does asphalt cure?
