Sealcoating: Protecting Your Asphalt Pavement from Water Infiltration

Wednesday, June 12th, 2013

PTG Enterprises is a full service commercial asphalt contractor in the Baltimore, Maryland area. We have been in the asphalt paving business for more than a decade, paving thousands of miles of asphalt lots during that time. And while asphalt may seem tough and durable, the effects of traffic and the elements take their toll, slowly breaking down the pavement over time. This is why Sealcoating is so important. Contrary to popular belief, sealcoating does a lot more than give your asphalt parking lot add aesthetic appeal.

Protecting Your Asphalt Pavement

Sealcoating: Protecting Your Asphalt Pavement from Water Infiltration

The biggest benefit of sealcoating is its ability to protect your parking lot or other asphalt surface from water infiltration. When water finds its way into the cracks and crevices in the surface of your asphalt, it works its way to the base, slowly eroding your parking lot from beneath. The end results are cracks, pot holes, and, eventually, premature pavement failure.

Sealcoating, which is essentially a thin liquid layer added over a paved surface, is designed to block water infiltration, protecting your asphalt surface and extending its useful life.

Additional Benefits of Sealcoating

  1. Fresh sealcoating has several benefits that will help protect your asphalt. However, there is one benefit of sealcoating that has nothing to do with asphalt longevity: Aesthetics. Simply put, fresh sealcoating will make your asphalt look great, giving it a dark black color. Plus, sealcoating makes your asphalt much easier to clean, allowing you to keep your parking lot looking its best.
  2. Over exposure to oxygen will harden asphalt binders, resulting in brittle pavement prone to cracking. Sealcoating can help.
  3. Sealcoating will help keep small cracks and asphalt degradation from growing and causing premature failure.
  4. Sealcoating will help block harmful UV rays, which can damage your asphalt surface.
  5. Sealcoating will also help protect your asphalt from damaging chemicals, like gasoline and oil.
  6. Sealcoating costs pennies per square foot. Asphalt repairs cost dollars per square foot. Needless to say, it is far less expensive to sealcoat your parking lot every few years than it would be to overlay or completely replace your parking surface.

How Does the Pavement Deteriorate?

Friday, June 8th, 2012

It has been estimated that ninety percent (90%) of asphalt roads in the United Sates have significant problems due to the deterioration of the base and sub-base material because of water infiltration.

Pavements where cracks have not been sealed, offer many routes for water entry into the base and sub-base courses. Water will penetrate through cracks that are over 1/8th to ¼ inch wide. Finer cracks also allow water infiltration into the pavement through the pumping action of the traffic; the surface water is pushed into the cracks when vehicles pass over the cracks. For cracks larger than ¼ inch, water flows in under gravity into the surface and the base course. Once water enters the base, the aggregate (limestone) absorb the water expand in volume and become soft, thus causing internal stress which accelerates the development of more and larger cracks.

There is no assurance that the pavement is not damaged if it looks fine on the surface. Not all deterioration will be visible. A study by Ontario’s Ministry of Transpiration, reported that on heavy traffic roads, half or more of the original asphalt pavement may disintegrate from the bottom up. In regions with extensive freeze-thaw cycles, with continuous thermal expansion and contraction of the pavement, the base and sub-base deteriorate much faster than in regions with moderate climates.

De-icing salts used in winter months further aggravate the problem. De-icing salt mixes with snow and forms a brine solution, which gets into the pavement and slightly melts ice in the base course. This produces even more thermal movement within the crack. The pavement weakened by a saturated base may experience localized failures when subjected to traffic. All cracked pavements will disintegrate and spall to various degrees depending upon the traffic volume or weight of the traffic load.

The Ins & Outs of Crack Sealing :: Pavement Maintenance Tips

Friday, May 25th, 2012

Asphalt may seem tough and durable, but add up the effects of traffic and the elements, and you’ll see how quickly commercial asphalt can wear down. So, like it or not, your asphalt pavement will eventually crack. That is just the nature of asphalt. What you do after your pavement cracks, though, is entirely up to you. And you have two choices:

  1. Do nothing and watch that small pavement crack quickly grow into a large problem. Once cracks develop, water easily penetrates into the base and sub-base of the pavement and damages the structural integrity of the aggregate materials.
  2. Crack Sealing!

Crack sealing is designed to minimizing water infiltration, thus protecting your pavement. In fact, crack sealing is one of the most cost-effective ways to prolong the pavement life. While crack sealing is a more costly option than crack filling, it does provide a longer life expectancy – lasting as much as 8 years or more.

Crack sealing – which utilizes a flexible, specially prepared hot pour rubberized sealant – is considered a permanent treatment and is the only effective treatment for active cracks that contract and expand between seasons.
