How Long Should I Wait To Pave My Driveway?

How long should I wait to pave my driveway? In general, a driveway should settle for six months before paving. This recommended time span will vary according to soil and weather conditions, and proper compaction can allow you to pave far sooner.

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.

What temperature can you blacktop driveway?

Ideally you want to install asphalt when both ground and air temperature are anywhere between 50 and 90 degrees. Anything below 50 or above 90 can cause a poor pour that will give you issues down the road.

What time of year should you seal your asphalt driveway?

Spring Is The Best Time To Seal Coat Your Asphalt

It means your driveways and parking lots look great for the entire year, and warm spring weather is the perfect temperature for a well-set coat. Plus, a fresh seal coat is easily damaged by winter machinery, like snow plows.

What if it rains on 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 before you can walk on a new asphalt driveway?

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.

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 are 3 types of asphalt?

There are three main types of asphalt: Hot Asphalt, MC Cold Mix, and UPM. There are also different varieties of these asphalts for summer and winter use. Below is a brief overview of each type of asphalt.

Can you asphalt in the winter?

The short answer is “no.” But we are sometimes able to start asphalt paving in late fall or early spring if the weather cooperates. The ground must be dry and not frozen for us to pave asphalt surfaces. This means no snow or rain.

Does asphalt cure faster in cold weather?

In terms of cold weather paving, what a contractor should be most interested in is the time they have available to achieve compaction. During cold weather, all things being equal, the asphalt mat will cool much faster than it will during warmer weather, shrinking the available compaction time.

How much does it cost to asphalt a driveway?

Paving an asphalt driveway costs $4,737 on average, with a range between $2,932 and $6,568. This project runs $7 to $13 per square foot, including $2 to $6 per square foot for materials and $5 to $7 per square foot for labor. If replacing asphalt, it will cost $8 to $15 per square foot.

How can I speed up my asphalt cure?

Asphalt cold patch mix cures by having contact with air. You can speed up the drying process by using hair dryers or commercial paint dryers. If you are going to use a hair dryer, you will need to manually operate it in a steady, sweeping motion to ensure even curing.

What is the best temperature to seal a driveway?

What's the best temperature to seal a driveway? The ideal conditions for application are during the day when pavement and ambient temperatures are at least 50°F and rising, and no rain is forecasted for 24 hours. If these recommendations are not followed, the procedure will not yield desired results.

Is asphalt sealing worth it?

Sealing an asphalt driveway gives it a fresh, black finish, but the job should be done only once every two or three years. Sealing the driveway yearly can lead to unsightly hairline cracks and peeling. Many people believe that concrete driveways don't need maintenance, so they may never apply a sealer.

How often should a blacktop driveway be resealed?

The process of curing enables oils to escape and prepares the pavement for the sealer. Once cured, a sealcoat should be applied promptly to protect asphalt from sunlight, extreme temperatures and other preliminary threats. After the initial seal, asphalt should be resealed once every three to five years.

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.

Should new asphalt be watered?

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.

How long does it take for asphalt to harden?

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.

Why is my new asphalt driveway not smooth?

If your asphalt isn't smooth and there are loose rocks scattered over the surface, or if you can kick loose small bits of asphalt or aggregate, it's very likely your pavement wasn't compacted properly. Asphalt compaction is extremely important because it removes the air from your asphalt.

How long does it take for asphalt to dry after rain?

While your driveway may be dry a day after paving, it still needs some time to cure. 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.

How thick should asphalt be?

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 is the best grade of asphalt?

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. The second grade, 85-100, is by far the most widely used material for plant mixes and is suitable for most pavements.

What type of asphalt is best for driveways?

Hot mix asphalt is considered best for driveways, because construction and design features are suitable to giving it a finished appearance that complements the home.

How can you tell the quality of asphalt?

  • Penetration test.
  • Ductility test.
  • Softening point test.
  • Specific gravity test.
  • Viscosity test.
  • Flash and Fire point test.
  • Float test.
  • Water content test.

  • Should you pave in the winter?

    In general, it is best to hold off on paving projects until we have gotten through the winter. However, we can pave in the winter as long as weather conditions are dry and the ground isn't frozen. In other words, cold weather asphalt paving can be done during mild winters or in late fall.

    Can you patch asphalt in winter?

    Cold patch asphalt can be installed in cold temperatures. The oils in the cold patch asphalt keep the mixture malleable enough to use in cold weather. While cold patch asphalt isn't a permanent solution, it should hold until the weather is warm enough to install hot-mix asphalt.

    How do you keep asphalt warm?

    As previously stated, hot asphalt will begin cooling as soon as it's deposited into the dump truck. As such, you, as the operator, must do all you can to keep it warm and mailable for a smooth delivery. One way to do this is by covering the top of the dump truck bed with a tarp or specially-designed cover.

    How hot is asphalt when it is laid?

    Asphalt Mix Temperature

    Not surprisingly, hot-mix asphalt is delivered to job sites at high temperatures. It usually arrives at temps between 275 and 300 degrees Fahrenheit.

    Is asphalt better in the winter?

    Asphalt paving projects utilize hot-mix asphalt, so it is not ideal to pave in the winter. If the ambient and ground temperatures are too low, they will chill the hot-mix asphalt while it is in transport from the production plant to your property. This is not good. The other type of asphalt is cold-mix asphalt.

    How can you tell the temperature of asphalt?

    Monitoring the base (ground or existing pavement) temperatures can be accomplished with an infrared thermometer (purchased at an instrument outlet, Sears, Home Depot, etc.) to assure the base temperature is 50° F and rising.

    Is 3 inches of asphalt enough for a driveway?

    Thus, a compacted asphalt thickness of 2.5 to 3 inches may be more than sufficient for a residential driveway, but a busy mixed-use lot may need a compacted asphalt thickness of 4 inches or more.

    Can you put new asphalt over old asphalt?

    The short answer is yes, you can put new asphalt over old asphalt. This can add several years to the surface. An asphalt overlay can last between eight to fifteen years on the surface. When applying asphalt over an old layer, make sure the new layer is at least 1.5 times thicker than the old one.
