1. Wait at least 3 full days before allowing traffic on the new asphalt. Since asphalt needs time to harden and cure, usually 6-12 months, your parking lot or driveway will remain soft and pliable until then.
Is 2 inches of asphalt enough for a driveway?
Residential driveways typically use 2 to 3 inches of asphalt with 3 being suitable for occasional large trucks or heavy equipment. Underneath the asphalt you should have 6 to 8 inches of granular base aggregate. Underneath this you have soil.
What happens if it rains on my new asphalt driveway?
So when rain comes into contact with fresh asphalt, it causes the oil to rise to the surface. In the case that newly-laid asphalt is subjected to rainfall or water, holes and cracks can form, eventually leading to a crumbling mess of potholes and other major pavement damages.
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.
Should I hose down my new asphalt driveway?
Even when fully cured, asphalt pavement can sometimes soften in extreme heat, or harden faster as temperatures drop. To temporarily harden the pavement, you can water down the surface with a garden hose. If soapsuds appear, don’t be worried. This is a reaction between the chlorine in the water and the asphalt.
How do you prepare the ground for an asphalt driveway?
The Complete 7-Step Process for Asphalt Pavement Installation Step 1: Demolition and Removal. Step 2: Grading and Sloping. Step 3: Prepare the Sub Base. Step 4: Proof Roll, Undercutting and Sub Base Repair. Step 5: Binder and Surface Course. Step 6: Install New Asphalt Surface. Step 7: Butt Joints and Transitions.
Does thicker asphalt last longer?
Adding extra blacktop thickness will not significantly extend the life of the surface. Keep in mind that blacktop is available in many different blends and mixtures. Each mixture has its own recipe of the sand, gravel and liquid asphalt components. Talk with each contractor and ask which blend is best for your area.
How long do you have to stay off fresh asphalt?
Normally, 24-hours is all that is required to use your new asphalt surface. In very warm weather, we recommend staying off the fresh asphalt for 1 – 2 days, as the surface cools.
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.
Is water bad for new 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 after rain can you lay asphalt?
Typically, you want to keep the pavement dry for at least two days, minimally, so make sure that rain isn’t going to be an issue before you start your driveway paving in this situation. Many homeowners may also want to talk about this problem with their paving experts before they even start.
What happens if you seal asphalt too soon?
If you seal too soon, you risk trapping the chemicals that make the asphalt flexible and more susceptible to tire marks, imprints, and cracking. Simply rolling a sealcoating machine onto soft asphalt has enough weight to leave an imprint.
Should I spray my new asphalt driveway with water?
Watering a New Asphalt Driveway Cooling down your asphalt driveway with water is recommended when outside temperatures are over 80°, as when it’s as hot as this, the asphalt can soften. Cold water will effectively stop the softening, and harden your driveway temporarily.
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.
Can you pressure wash new asphalt?
Homeowners can use a pressure washer to clean their asphalt but should always use caution to not damage the asphalt and should always reseal after a thorough cleaning.
Can you put asphalt over dirt?
Yes, you can blacktop over gravel. If anything, Over 90 percent of the roads in the US are surfaced with blacktop (preferably known as asphalt).
Can you pour asphalt over gravel?
Yes, it’s possible to get your gravel driveway paved with asphalt. The process requires a few reasonably easy steps that need to be implemented to complete the paving project. You can pave straight over gravel or strip the gravel and start new based on the situation.
Is asphalt better than concrete?
Concrete is more durable than asphalt. Because it is a less flexible material, it cracks in freezing temperatures, and many people turn to concrete patching products. Though it is more durable overall, when damages do occur, concrete repair is harder and costlier than asphalt repair.
Can you put asphalt over concrete?
It is safe to pave asphalt over concrete. Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. In fact, many miles of concrete roads are paved over with asphalt every year.
How thick is the asphalt on a highway?
For standard commercial jobs, the dense-graded aggregate layer is typically about 8” thick. On top of the base, we typically recommend applying two 1.5” layers of asphalt. The first binder layer of 1.5” would be a thicker stone.
Are there different grades of asphalt?
The Asphalt Institute specifies four penetration grades: 60-70, 85-100, 120-150, and 200-300. The 60-70 grade is usually used only in pavements where traffic is very heavy such as principle city streets and very heavily trafficked rural highways.
