Sealcoating for Winter Asphalt Protection

Water is the enemy of asphalt. When water seeps into and under asphalt, it can cause deterioration, settling and other problems. Winter can be the worst time for water penetration into asphalt. If it is in or under the asphalt, it can freeze, expanding and contracting. This can cause cracking and premature wear on asphalt. To protect asphalt from winter damage, routine sealcoating can be the best option.

What Is Sealcoating?

Sealcoating is the best way to extend the life of asphalt surfaces, including driveways, parking lots and basketball courts. This process should be done for the first time a few months after asphalt is installed, then every 2-3 years afterward. This coating seals the asphalt and protects it from water penetration. As the sealcoating wears off, the asphalt becomes vulnerable to moisture. If it has been over two years since the last sealcoating, it is a good idea to perform this process before the next winter arrives.

Sealcoat Asphalt in Mild Temperatures

While sealcoating is needed for winter protection of asphalt, it needs to be done when it is dry and warm. It is best to have this service performed before temperatures drop too low or wet weather is the norm. You should have a stretch of 3-4 dry days with temperatures above 50 degrees to ensure the sealcoating process is completed correctly. Besides protecting the asphalt, sealcoating can make the surface look new again, an extra benefit of this procedure.

Sealcoating can help asphalt surfaces last for 20 years or more, surviving decades of wet or cold winters. Make sure your asphalt surfaces are protected with routine sealcoating every few years.

Summer Is A Great Time To Apply Seal Coating

If you have a new asphalt driveway or parking lot, or an older asphalt surface which is beginning to show signs of wear, now is the time to apply seal coating. Seal coating can extend the life of your paved surface for many years to come, plus make it look like new if it’s starting to fade. For effective seal coating, the temperature must be warm enough for it to adhere, so summer is a great time to schedule your service. 

Can I Do Seal Coating Myself?

Although there are do-it-yourself products to apply asphalt sealcoating on your own, it is best to let professional paving contractors perform this task for you. For one, the monetary savings is not usually very substantial when you consider the time and effort it will cost you to do on your own. In addition, paving contractors use professional equipment to ensure that the seal coating is evenly spread without pooling. They also will know which seal coating products work best in your region, making it worth the extra cost to have them get the job done right the first time. 

How Often Should I Have Seal Coating Applied?

There is not a set amount of time that seal coating should be applied to asphalt. It all depends upon the weather where the asphalt is located and the amount of traffic the surface must handle. In general, every 2-4 years, seal coating can be added. However, you should have a professional inspect your surface before adding more seal coating. Adding it too often can be harmful to your asphalt. 

Call your local paving contractor today to have your asphalt inspected if you think it may need seal coating. They can let you know whether it is a good time to add new seal coating or if you should wait until next summer.

The Benefits of Asphalt Seal Coating and Crack Filling

The longevity of your asphalt surface (parking lot, etc.) can be extended through maintenance. 

Three excellent ways to get the most out of your asphalt are:

  • Seal coating
  • Crack filling (sealing)
  • Patching

Seal Coating

When compared to replacing your entire asphalt surface, sealcoating is very inexpensive.  In fact, the replacement of your asphalt surface will likely cost you twenty (20) times more money than simply applying seal coating on a regular basis. You can extend the longevity of your asphalt surface by as much as two to three times just with an application of seal coating every two years. 

Seal coating does the following:

  • Naturally fills the porous areas of your asphalt to provide protection against the erosive effects of salt, water, chemicals, and oil
  • Reduces weather damage, especially damage caused by the freezing and expansion of water.
  • Protects your asphalt against the sun, which tends to dry out the asphalt surface
  • Gives your asphalt a beautiful, new look

Crack filling (sealing)

Filling or sealing cracks in asphalt is one of the primary ways to stop deterioration.  By regularly inspecting and repairing cracks, you prevent the problem from becoming worse. Thus, you save yourself a lot of money from more costly repairs or resurfacing. 

Other benefits include:

  • Prevention of water from infiltrating and weakening your asphalt’s base
  • Preservation of the pavement next to the cracks
  • Prevention of dirt, sand, and stones from causing additional stress and larger cracks
  • Extension of your asphalt pavement’s longevity by combating the growth of cracks

Sealcoating

Sealcoating is a thick mixture of liquid coal tar or asphalt that is applied as a protective coating to asphalt pavement.  Asphalt is an excellent paving choice for driveways, parking lots, and roads. It is waterproof, flexible, and adhesive so it binds together the aggregates in the pavement.  It is by far the most popular choice for roads, parking lots and driveways. 

Asphalt pavement consists of a roadbed made of stone aggregate covered by a layer of asphalt cement mixed with aggregate.  This top layer is often called “blacktop.” The underlying stone aggregate carries the weight of the vehicles and the blacktop provides a smooth surface and protects the roadbed from water.  Protecting the stone aggregate layer from water intrusion is one of the most important jobs for the blacktop asphalt surface.

Exposure to sun, rain, petroleum products, salt, and other chemical causes asphalt to deteriorate over time.  As asphalt deteriorates, cracks form that allow water to intrude into the roadbed below.  Once the roadbed gets wet, it its ability to support the weight of vehicles will diminish causing dips and ruts which will cause further damage to the asphalt surface. Freezing weather conditions will accelerate the process. 

Regular asphalt sealcoating adds a protective coating to the surface of the asphalt which helps protect the asphalt from the elements and prevents water from intruding into the roadbed below.  An asphalt driveway or parking lot should be sealed whenever it starts looking weathered.  This will depend on a lot of factors including exposure to the elements, usage, whether it has been sealed before, the quality of the initial installation and the sealant used.  In general, sealing an asphalt surface every one to three years is typical.
