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 a paved road 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.
How soon can you drive on asphalt?

How long does asphalt need to dry before rain?
Generally, new asphalt can get wet after 24 hours, with two to three days being ideal. Rain is the enemy of asphalt when paving. Rain will make asphalt dry slower, and working during rain will damage asphalt in most cases. So, when paving, try to look for a few sunny days before rain.
Will rain ruin new asphalt?
In general, asphalt cannot be installed when it is raining. 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.
How long does it take for asphalt millings to harden?
Expect to wait at least 24 hours before standing on your new asphalt. You can walk on the asphalt the next day, as the drying process continues. However, high heels and cleats can leave imprints in your day-old asphalt, so avoid these shoes, car traffic, and any other heavy or sharp objects for at least three days.
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.
Why do they put sand on new asphalt?
Asphalt cement is the binder, or glue, that holds together the sand and stones that make up a blacktop drive, road or parking lot. The stones and sand in blacktop are immune to UV damage from the sun.
How soon after asphalt is laid should it be sealed?
After laying asphalt, you should wait at least 30 days before sealing your commercial parking lot. For residential parking lots, it is best to wait 90 days. Otherwise, you risk sealing your new asphalt before it is hard enough to withstand elements like power steering.
How long does it take for cold patch to harden?
Avoid getting Asphalt Cold Patch on hands or clothing. Avoid dry turning tires on patched area until the material has hardened sufficiently (certain weather conditions may extend this period). Allow repaired area to cure for a minimum of 30 days (preferably 90 days or more) before applying driveway sealer.
Should you water fresh asphalt?
Even when cured, asphalt can sometimes soften in extremely hot weather and harden as temperatures fall. To temporarily harden hot asphalt, you can water it down with a garden hose. Do not be alarmed if soapsuds appear. Large, heavy vehicles can depress your new asphalt and create ruts in your new blacktop.
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 does asphalt smell in rain?
It is caused by the water from the rain, along with certain compounds like ozone, geosmin, and plant oils. and in soil. When it rains, these compounds are released into the air to add to the earthy smell of petrichor.
Does asphalt milling Harden?
It is basically a ‘cold mix’ asphalt laid and rectified at the surrounding outdoor temperature. Once the asphalt millings are laid perfectly, a steamroller is used to compact it to get the best finish. After getting it properly compacted, the surface will harden quickly within a few days.
How thick should asphalt millings be?
For the record, for parking areas and driveways on soil, millings are usually at least 4, but preferably more than 6 inches thick, and should be compacted thoroughly before exposed to traffic.
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.
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 cold is too cold for 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.
