Are you planning an asphalt project? Whether paving a driveway or resurfacing a parking lot, you need to know how long it will take for the asphalt to dry. In this blog post, we’ll discuss the factors that affect drying time and provide tips on how to get your project done quickly and safely.

What Is Asphalt

Asphalt is a mix of bitumen, a petroleum by-product, and crushed stone or gravel. It is used to make pavements, driveways, and parking lots because it is strong and durable. Asphalt is also easy to install, which makes it a popular choice for many construction projects.

It is applied in layers; each layer needs to dry before being covered with the next layer. To ensure that asphalt is properly laid and cured, it is important to know how long asphalt takes to dry.

How Long Does Asphalt Take to Dry?

Generally, you can expect new asphalt to take anywhere from 48-72 hours to dry completely. However, the exact drying time will depend on the weather conditions. If the weather is particularly humid or there is a lot of precipitation, the asphalt will take longer to dry.

The Ideal Weather Conditions for Laying Asphalt

The ideal weather conditions for laying asphalt are dry and sunny. The temperature should be at least 55°F (13°C) during the day and not drop below 40°F (4°C) at night. The asphalt should also be laid during a dry period of at least 3 days without rain. This will ensure that the asphalt has enough time to dry and cure properly, allowing it to last for years.

How Temperature Affects the Drying Time of Asphalt

Temperature plays a critical role in the drying time of the asphalt. The warmer the temperature, the faster the asphalt will dry. In warm weather conditions, asphalt can fully dry in as little as 2 hours. However, the asphalt may take up to 48-72 hours to dry in cooler temperatures.

Also, the temperature is too hot can cause the asphalt to crack or become brittle. For this reason, it’s important to ensure the temperature is just right when laying asphalt so that it dries properly.

The Effects of Humidity on the Drying Time of Asphalt

Humidity can have a significant effect on the drying time of the asphalt. If the humidity levels are high, the asphalt takes longer to dry. This is because the moisture in the air prevents the asphalt from evaporating and drying quickly.

Humidity can also cause asphalt to cool more slowly, making it harder to set and dry properly. To ensure proper drying of asphalt, ensure that the humidity is not too high when paving or resurfacing a parking lot or driveway. Additionally, high humidity levels can prevent it from drying completely if using a curing compound to seal your asphalt.

Factors Impacting the Drying Time of Curing Compounds

Curing compounds are often used when installing asphalt to help reduce drying time. These compounds help to bond the asphalt together and reduce the moisture content in the mix. They can also help protect the asphalt from cracking or crumbling due to extreme temperatures.

However, if you’re using a curing compound with a slow-drying formula, it may take up to seven days before your asphalt is ready. You can take a few simple tests to check if your asphalt is dry enough for use. The first is to touch the surface and feel for any stickiness or give. If there’s no stickiness or give, your asphalt should be dry enough for use.

What You Need to Do to Help Speed Up the Process

Once you’ve got the ideal weather conditions for laying asphalt, you can do a few things to help speed up the drying process. If you’re using a curing compound, it’s always best to apply a thicker coating. This will help the compound dry faster since the thicker coating will absorb more heat from the sun.

You can use heaters or fans to help speed up the drying process. The combination of heat and airflow will help evaporate any standing water and help your asphalt dry faster. You should also ensure that any vehicles or heavy equipment are kept off the freshly laid asphalt until it is completely dry. This will help prevent any damage and ensure that your asphalt is properly cured before it is used.

Using a Combination of Heat and Airflow to Quicken Drying Times

Combining heat and airflow can greatly reduce freshly laid asphalt drying time. The heat from the sun and air from a fan or blower can help to speed up the evaporation of the liquid tar contained in asphalt.

This can reduce the drying time from two or three days to just two or three hours. However, it is important to remember that this does not mean that your asphalt is cured and ready for use. The asphalt still needs time to harden and cure before it is safe to walk or drive on.

How To Tell If Your Asphalt Is Ready For Use

You can try the “footprint test” by pressing your foot down on the asphalt. The asphalt is still too soft for use if the footprint remains visible and doesn’t fill in after a few seconds. Finally, you can try the “water test” by sprinkling water on the asphalt surface. If the water beads up and doesn’t soak in, your asphalt is still too wet for use.

The Best Way To Make Sure Your Asphalt Is Fully Cured Before Use

The best way to ensure your asphalt is fully cured before use is to wait for the recommended time before allowing foot and vehicle traffic on it. This period is usually between 48-72 hours for fresh asphalt and 2-3 hours for resurfaced asphalt.

Waiting for the recommended period allows the asphalt to dry properly and cure, making it much more durable and resilient. Additionally, it’s important to consider your environment’s temperature and humidity when determining your asphalt’s drying time.

If the weather conditions are not ideal, you may need to wait an extra few days before allowing traffic on your new asphalt. Finally, it’s important to note that asphalt takes at least 6-12 months to cure and reach its maximum durability completely, so be sure to maintain proper care of your asphalt surface to ensure its longevity.

Preventing Damage During and After Installation

Installing asphalt correctly is key to ensuring that it dries and cures properly. When laying down asphalt, it is important to avoid overworking the material, as this can cause it to dry too quickly and become brittle. If the temperature is too high, the asphalt may not be able to cure before it is used properly. Additionally, any large objects, such as vehicles, should not be driven over asphalt until it has fully cured.

It is important to use a curing compound to help prevent damage during and after installation. A curing compound is a liquid material that helps keep moisture in the freshly laid asphalt and prevents it from drying too quickly. It also helps protect against UV damage and keeps the asphalt flexible, which can help prevent cracking.

Tips To Help Maintain Properly Installed and Cured Asphalt Surfaces

Maintaining asphalt surfaces is essential for ensuring they last as long as possible. Properly installed and cured asphalt surfaces will stay in better condition for longer, but there are some tips you can follow to help maintain them.

Make sure to clean your asphalt regularly. This will help prevent dirt, debris, and moss buildup, which can lead to cracks and other damage. De-icing salts should also be avoided, if possible, as they can erode the surface of the asphalt over time.

Seal coating your asphalt every few years is important for protecting it from the elements and helping to keep it looking its best. You should also strive to keep the surface level throughout its lifetime. If you must make repairs, use materials compatible with your existing asphalt.

It’s also a good idea to regularly check the surface for any signs of wear, tears, or cracking. If you notice any damage, it’s important to address it as soon as possible to prevent further deterioration.

Finally, keep the area around your asphalt clean and free of any objects that could damage the surface. This includes tree roots and large rocks, which can cause cracks and other damage over time.

Following these tips can help you maintain your asphalt surfaces for years to come, ensuring they stay looking their best for as long as possible.


When it comes to asphalt, it’s important to understand how long it takes for the material to dry before use. Depending on the weather conditions, the process can take anywhere from 48-72 hours for a fresh installation and up to a week for a resurfaced installation.

The ideal conditions for laying asphalt are dry, mild temperatures, and low humidity. If you take the necessary steps to ensure that your asphalt is properly cured and sealed before use, you can prevent any potentially costly damage to your surface. Your asphalt should last for at least 30 years with proper maintenance and care.
