4 Key Causes Of Asphalt Deterioration

4 Key Causes Of Asphalt Deterioration

Asphalt is one of the most preferred paving materials across the US. Around 94% of the paved roads are made of asphalt, as its durable, resistant, and robust nature entice many property owners to opt for asphalt.

However, despite its long-wearing characteristics, asphalt is not immune to damage and deterioration. Any asphalt pavement that is not adequately maintained will start showing signs of degradation and ultimately break if not repaired on time.

At Quality Asphalt, we make sure your asphalt pavement stays in prime condition for several years. Our professional paving contractors in Howard use advanced maintenance techniques to protect the asphalt from harmful elements and prevent early degradation. With our help, you can maximize your asphalt’s life with relative ease. Connect with us today!

In today’s blog post, we’ll uncover the top four causes of asphalt deterioration.

1. Water Pooling

An efficient drainage system plays a significant role in maintaining the condition and performance of asphalt. Otherwise, water starts pooling over the asphalt, which compromises the pavement’s structural integrity and ends up cracking/breaking the asphalt.

Therefore, make sure all drains are in good working condition for efficient water flow. You can also sealcoat the pavement to form a protective layer over asphalt to prevent water from seeping under the surface.

2. Heavy Materials/Traffic Load

As much as water is harmful to asphalt, so is heavy material or traffic load. So, whether you have newly paved asphalt or old pavement, make sure not to expose the pavement to heavy material or traffic load. These can cause stress on asphalt surfaces, which leads to unevenness, cracks, or potholes.

If the placement of the material or vehicle is necessary, remember to change their positions throughout the day. This will distribute the pressure/load, and your asphalt will remain intact for a more extended period.  

3. Chemicals / Oil Stains

Chemicals or motor oil have the tendency to penetrate and break down asphalt. If not cleaned on time, they leave stains on the pavement, weaken the top layer of asphalt, and compromise the elasticity of the liquid asphalt binder.

You can mitigate the risk of damages by cleaning up all chemical or oil spills and stains. Moreover, sealcoating can help slow down the asphalt aging process.  

4. Oxidation

Excessive oxygen exposure hardens asphalt and makes it less flexible. So, when asphalt contracts and expands during the winter and summer season, respectively, it starts to crack.

You can prevent this by sealcoating the surface every two to three years. Sealcoating prevents oxidation and extends the lifespan of your asphalt in a very cost-effective manner.
