Potholes and Repair

Wednesday, March 30th, 2011

How do potholes happen?

Potholes are severe manifestations of pavement fatigue cracking resulting in a total loss of asphalt integrity in a localized area. This creates a hole in the road. It is not uncommon to have a pothole extend through or into the aggregate stone base. Potholes occur when water seeps into cracks in the asphalt surface of a road or driveway. This water will freeze and expand in the cold weather. A pothole forms when dirt and gravel are forced out leaving a hole. The ice will eventually melt away, leaving a pothole.

How can you quickly fix a pothole in your driveway?

For a very wide crack or pothole, shovel in packaged cold-patch blacktop, leveling large areas with an iron rake. Compact the material with a rented tamper or the end of a 4-by-4. Add more material until the hole is slightly overfilled. Cover it with scrap plywood and drive over it.

If you are looking to fix a pothole on a commercial parking surface or if you want a top quality repair, it is probably best to call a professional.

What does My Pavement Guy have to say on the subject?

In the winter, potholes should be temporarily filled with a cold-patch mix material to protect against vehicle damage and/or lawsuits. Please note that this is only a temporary fix and left untreated correctly the pothole will most likely reappear. In the spring and summer months, potholes should be permanently patched.

Full-Depth Patching is the most common type of patching. This is where the pavement is completely removed in the troubled area and replaced. These areas are usually suffering from severe distress and / or sub-base failure. This is a permanent fix.

Pavement Maintenance

Wednesday, March 23rd, 2011

From the moment your asphalt is installed, it begins to deteriorate. This means that to ensure you have a top-notch parking lot for years to come, you will need to take certain steps to maintain that asphalt. This preventative maintenance will not only make your parking lot last longer, but, in the long run, it will save you money.

Here are a few simple steps you should take to keep your lot looking pristine.

Crackfill

Properly filling cracks is a job of tremendous importance. By filling a small crack properly, you will prevent that fissure from growing and becoming too big to handle by yourself. Filling small cracks saves you from paying to have large cracks repaired.

Sealcoating

This is another great way to improve the overall look of you lot while going the extra mile to protect your parking surface.

Re-Striping

Once the original lines are painted on the asphalt, constant re-striping is required ever 12-18 months.

Signage

Not only will your lot begin to deteriorate, but often signs are knocked down, dented, vandalized or even stolen. It is important to properly maintain your signs – not only for that instant curb appeal, but also for safety.

Wheel Stops

Wheel stops play an integral role in maintaining clear sidewalks and protecting signs. If your wheel stops are damaged, it could negatively affect everything around them.

Now you are well on your way to a beautiful, long lasting parking surface.

Benefits of Sealcoating/Resurfacing Treatment

Monday, March 21st, 2011

No matter what material your parking surface is made from, it can benefit from sealcoating or resurfacing treatment.

Unsealed pavement can allow water and other foreign materials to penetrate into its surface – leading to base erosion, freeze-thaw damage and pavement failure. Sealcoating provides your pavement with a protective barrier, which will not only make your lot last longer, but will also give your parking surface some instant curb appeal.

The Asphalt Institue states that, “The accumulation of moisture in pavement is probably the greatest cause of pavement distress.”

So do not wait for your lot to start cracking before you address the situation. Be proactive and sealcoat your parking surface as soon as possible.

As pavement cures, the sun’s rays dry out the asphalt – making the surface brittle. This oxidation causes accelerated erosion and if left untreated it can reduce asphalt thickness by as much as half within five years.

Take the necessary steps to keep your parking surface in great condition. A new sealcoat can restore that fresh black color to your lot. Not only will it last longer, but it will also look better.

Asphalt Causes Less Carbon footprint than Other Pavements

Friday, February 18th, 2011

The production and installation of asphalt emits less greenhouse gases than other surfaces, reports this article. According to a recent study, asphalt pavements require about 20 percent less energy to produce and construct than other pavements. The less fuel that is used in the process—the less carbon dioxide that gets released into the air.

The article goes on to say that “Between 1970 and 1999, the asphalt industry decreased total emissions from plants by 97 percent while increasing production by 250 percent. Emissions from asphalt plants are so low, the EPA considers them as only minor sources of industrial pollution.”

Warm mix asphalt is another way that asphalt is cutting down on its emissions. The asphalt is mixed at a lower temperature than before, thus needing less energy to heat up.  Asphalt also helps to move traffic along quickly, allowing drivers to get to their destination rapidly. The process for applying asphalt is very fast so traffic does not usually result. This saves drivers time and also helps cut down on carbon dioxide released into the air.

The urban heat island (UHI) effect—the phenomenon that makes cities 2° to 10°F warmer than nearby rural areas on a hot summer day is another issue to consider. However, recently it has been proven that it is not necessarily the color of the pavement in the city that causes this effect but also the texture and thickness of the pavement.  This can affect the way a pavement retains, radiates, and/or releases heat. Research is being done to now to look into more porous surfaces that can help lessen this effect.
