Common Asphalt Driveway Questions?

EARTHTEKNovember 14, 2022

When installing a new residential driveway, it's normal to have questions. For example, residents want to know if specific driveway materials, suit their homes or businesses. Besides cost-effectiveness, factors like curb appeal also play a role. 

In this guide, we'll answer some common asphalt driveway installation questions we get the most. 

How Long Should an Asphalt Driveway Last?

Many people ask, "How long does an asphalt driveway last?" Following the proper asphalt driveway installation, you can expect your driveway to last between 15 to 20 years.

Extending your asphalt driveway's durability and lifespan requires regular maintenance. 

Can You Put Asphalt Over Old Asphalt?

Suddenly seeing cracks on your asphalt's surface may make you want to replace your asphalt. However, installing an asphalt overlay is possible if your driveway is still maintaining its structural integrity. 

Before installing the overlay, a contractor must first repair any damage. Sometimes this process only involves releveling (milling) your asphalt driveway surface. Other times, however, it requires extensive repairs. 

Depending on the driveway, you can expect an overlay depth of around 1.5 to two inches. Many people pursue overlays because they're far cheaper and less time-consuming than asphalt replacements. 

Is It Necessary to Seal an Asphalt Driveway?

Applying a driveway sealcoating is strongly recommended for regular driveway maintenance. Driveway sealcoating provides many benefits. 

Sealcoating can protect your asphalt from the sun's ultraviolet rays. It also protects your asphalt driveway from the air's oxygen, which can make it brittle. Brittle asphalt looses its flexibility thus more prone to cracking. Additionally, this coating can protect your driveway from car fluids like antifreeze, oil, and gas. 

Is It Normal for Asphalt to Crack?

Even with proper installation, sealcoating, and maintenance, your asphalt is still susceptible to cracking. Many issues can lead to your asphalt cracking, including the following: 

  • Sun exposure 
  • The ground shifting 
  • Traffic from heavy vehicles or equipment 
  • Your asphalt's age
  • How much you use your asphalt driveway 
  • Dramatic changes in temperature and humidity 
  • Weather events like high winds, rain, and snow

While there's no way to completely prevent a driveway from cracking, some solutions exist. Alongside regularly sealing your driveway, monitor for cracks and sealing cracks.. 

How Thick Should a Driveway be?

For residential asphalt driveways, you should aim for two or three inches. However, using three inches for heavy trucks or equipment is better. Underneath your asphalt driveway, you'll also want to add a six to eight-inch granular base aggregate. 

Use at least four to 8 inches of asphalt with an eight-inch granular base aggregate for commercial parking lots paving

What Is the Best Time of Year to Pave a Driveway?

The best time to call a driveway paving contractor is summer or spring. During these seasons, temperatures are hotter, and it's better to pave asphalt driveways at 70 degrees Fahrenheit or more.  

Should I Seal the Cracks in My Driveway?

Although cracks in your driveway are common, they also indicate structural weaknesses. So to save money, driveway owners sometimes fill these cracks. 

However, while less expensive, filling cracks is only a temporary solution. Sealing cracks can significantly extend your driveway's lifespan.  

How Often Should I Sealcoat My Driveway?

There's no one rule on how often you should sealcoat your asphalt driveway. This timeframe depends on factors like how much you use your driveway, your area's temperature, etc. 

While there's no hard rule on when to sealcoat your driveway, our team recommends this process every three to four years.
