What Causes Asphalt Pavement Deterioration?

Thursday, November 29th, 2012

Asphalt pavement is both durable and resilient. And it has to be. Asphalt pavement takes a beating on a daily basis. Between regular traffic and Mother Nature, your pavement needs to be strong. However, over time, even the toughest asphalt will start to deteriorate.

What Causes Asphalt Pavement Deterioration?

There are actually a few likely causes of pavement deterioration, including:

  1. Natural Wear and Tear: Over time, the materials that make up asphalt begin to deteriorate. The liquid asphalt binder, the glue that holds the pavement together, begins to lose its natural elasticity and starts to break down. During this process, the asphalt also loses its natural resistance to water, making the pavement even more susceptible to rain, snow, freezing and thawing, and more. Once this happens, cracking and other forms of deterioration are not far behind.
  2. Failures in Construction: Improperly installed asphalt can be a large reason for the deterioration of your pavement. Failures in construction can include: improperly compacted base, over or under compaction of the asphalt, improper temperature during application, poor drainage, and so much more.

Types of Asphalt Deterioration

  1. 1. Cracking: Cracking comes in many different forms, from alligatoring and edge cracks to slippage, reflection, and more.
  2. 2. Disintegration: This type of deterioration includes potholes, raveling, and the like.
  3. 3. Distortion: The result of improper pavement construction and the deterioration of the underlying base, distortion includes channels or ruts, corrugations and shoving, grade depressions, upheaval, and utility cut depressions.

When asphalt is installed properly and well maintained, it can last for 25 years or more! So trust your asphalt to a contractor with a proven track record of success, a contractor like Patrick Gillen of PTG Enterprises.

Asphalt Pavement Deterioration: Maryland DC, & Virginia Asphalt Contractor

Friday, September 14th, 2012

Asphalt is used everywhere, from roads and parking lots to runways and more. And why not? Asphalt boasts several benefits, including:

  • Asphalt has excellent waterproofing properties.
  • Asphalt has excellent binding (or cementing) properties to hold the aggregates in the pavement.
  • Asphalt pavement has a long life & resurfacing is quick.
  • Asphalt is America’s most recycled material.
  • Asphalt is the most sustainable and environmentally-friendly pavement on the market.
  • And more!

Still, asphalt has a few major deficiencies as well. Asphalt has very poor resistance to weathering and is easily attacked by chemicals, gasoline, oils, and deicing salts. All of these elements work together to break down the asphalt, degrading the asphaltic oils from the surface as chemicals dissolve them away. And with the loss of asphalt cement, the aggregates in the top layer begin unraveling and develop the first sign of pavement deterioration; the appearance of minor surface cracks.

Over time, cracking will become more prevalent. And if not repaired, these cracks will allow water to penetrate sub-base and base layers, causing them to lose their ability to effectively bear traffic loads. Eventually, this will cause the asphalt pavement to fail.

To prevent further erosion of your asphalt pavement, or to fix a problem so it does not get any worse before winter, call PTG Enterprises for a property evaluation. You can expect a fair proposal, professionalism and quality work.  A good contractor is hard to find!

What is Asphalt Maintenance? My Pavement Guy Answers FAQs

Friday, July 20th, 2012

Over time, even professionally installed asphalt undergoes a tremendous wear and tear, causing it to crack and fail. Asphalt maintenance refers to the methods and techniques used to prolong the useful life of asphalt pavement.

Types of Asphalt Maintenance

  • Asphalt Patching: his 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.
  • Asphalt Crack Filling: Crack sealing can reduce pavement deterioration by restricting water penetration into underlying base and sub-base layers. As part of a preventative pavement maintenance program, crack sealing / crack filling extends the life of your pavement surface.
  • Asphalt Overlay: An overlay is when a new and additional layer of asphalt is installed over what is already there.
  • Asphalt Sealcoating: Sealcoating is a preventative maintenance measure that helps safeguard a parking lot against the harsh effects of gas, oil, salt, weather conditions and oxidation. When applied properly, a sealcoat cures on your parking lot leaving a fresh black finish (protective layer).

If you notice your parking lot or any asphalt pavement displaying signs of deterioration, it is probably time to call an asphalt contractor, like PTG Enterprises, to help prevent further damage. Do not put this off and let small cracks become major problems.

Sealcoating Performance: Frequently Asked Questions (FAQs)

Friday, June 15th, 2012

I have had the opportunity to respond to many questions pertaining to sealcoatings, based both on refined tar and asphalt, during my many years of lecturing and day to day service to our customers. The following is a condensed list of questions and my answers which are frequently asked.

Q.1. Why are two thin coats of a sealcoating is better than one thick coat?

A.1. Sealcoatings applied in two coats dries and cures much better than one thick coat application. Sealcoatings are commonly water-based coatings, which cure through the process of water release (evaporation). Also, sealcoating film dries from top to bottom, meaning top layers dry faster then from the bottom layers. A thin coat will release water much faster than a thick coat. If the sealcoating is applied in one thick coat instead of the recommended two coats, it will have a tendency to hold water and stay soft for a longer period of time, possibly causing tracking.

Q.2. Why apply two coats, when one coat looks good enough?

A.2. Appearance is only part of the benefits. The sole purpose of sealcoating is to protect and preserve the asphalt. One coat will possibly provide only half of the protection and will wear out in less than half the time. You will have to sealcoat more frequently if you used only one coat.

Q.3. Why did the sealcoating fail or peel?

A.3. Peeling is caused by sealcoating not bonding to oil spots or any other surface contaminants like dirt, grease, etc. or oxidized pavements. Prior to sealcoating application, the pavement surface shall be thoroughly cleaned, oil spots be treated with an oil spot primer. And oxidized surface be primed either with a specialty primer or a thin coat of the sealer or a tack coat.

Peeing and dis-bonding, may also be caused by freezing temperatures during the final cure process, before the film was fully cured. Freezing temperatures will shatter the sealcoating bonds from the bottom layers of the sealer film.
Deposit of tree sap in the pavement profile. The failure is seen as the flaking of the sealer.

Sealcoating over a very hard coating, e.g. Gilsonite-based. The failure appears as chipping because the top coat does not bond and flex with the bottom coat.

Q.4. What causes white streaks in the sealcoating?

A.4. It may be an indication of a problem with the base itself. The limestone from the base may be coming up with water though pre-existing cracks in the pavement. (details in a previous article published here).

If not, then contact your sealer manufacturer to be assured that that the material in question was processed adequately to mix the clay and fillers during the processing.

Q.5. Why does the sealcoating dry gray?

A.5. The graying is caused by sealcoating drying under less than ideal conditions, e.g. shaded areas, cooler temperatures, high humidity, etc. The problem is mostly temporary i.e. after a few days in full sun it will cure to its normal color. Temporary graying can also be eliminated through the use of specialty additive that helps sealcoating dry faster and at a uniform rate. If the problem persists and the sealcoating does dry to its characteristic charcoal black color, the manufacturer should be consulted.

Q.6. Why does the sealcoating wear out faster in traffic lanes, entrances and exits?

A.7. Aside from the obvious reason of more traffic in those areas, it could be an adhesion problem, If the wear is excessive. The surface aggregates in these areas become smooth (polished) over the years of usage. For any coating, including sealcoatings, to bond properly, it is imperative that the surface be sufficiently rough. Our recommendation is to use a specialty primer to prime faster traffic lanes, exits and entrances. These primers penetrate the smooth polished aggregates and allow the sealcoating to bond effectively.

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.

The Asphalt Driveway Repair Process

Friday, November 25th, 2011

Is your asphalt driveway in desperate need of repair? Well, the only way to truly rehabilitate your parking pad is to hire a professional asphalt contractor to come in, assess the situation, and repair the problem.

While you can attempt small do-it-yourself asphalt patching jobs on your own, these will be little more than temporary solutions. In the end, the only way to truly repair your driveway is to have an asphalt professional, like PTG Enterprises, handle the project.

Here at PTG Enterprises, we adhere to the following Asphalt Driveway Repair Process:

1. Pre-Construction

The purpose of a pre-construction meeting is to clearly communicate expectation levels and set a time to allow a question and answer session. A successful pre-construction meeting results in everyone leaving with a clear understanding of what’s going to happen and when it’s happening. Most of the time, this information is discussed at the time of estimate.

2. Traffic Controls

Usually this consists of cones and caution tape. We will place cones around construction vehicles and at both ends of the work zone. Maintaining the safety on a work zone is of the utmost importance. Once the driveway repairs have been completed, caution tape will be placed across the entrance to allow the asphalt time to cure.

3. Base Patching – (IF NEEDED)

As described in several places through-out this website, most patching is conducted the same way. The damaged asphalt is excavated, in this case to the sub-grade stone, and all damaged asphalt is removed from site and disposed of at a recycling plant. Assuming the sub-grade is stable, (see “Undercutting” if not), new asphalt is installed within the excavated area and compacted within industry standards. With base patching, the finished grade of the patch is even with either the old existing pavement that is about to be overlaid or even with the milled out elevation of the parking lot. In both cases, base patching is designed to repair isolated damaged areas prior to an overlay.

4. Undercutting / Stone Replacement – (IF NEEDED)

Soft spot or unstable soil is usually easy to see and evaluate. A simple on-site test is a proof roll. For this you take a fully loaded dump truck (approx. 50,000 pounds) and drive it over the area. In smaller areas, a bobcat will work. If the truck / bobcat cause deflections or makes deep wheel rut impressions in the sub-grade, you have a soft spot. The area is excavated as needed until a stable soil is reached and all debris is removed from site. New stone is then reinstalled in lifts, building the area back up to pre-construction elevations. The area is then capped with base course asphalt if overlay is to follow or base and surface course asphalt if it is to be a finished patch.

5. Asphalt Installation

The paving machine, paired with an experienced operator and a trained crew, will make paving look easy – it’s not. Assuming fabric was not in the scope of work, than the paving team will have a man designated to either spray or spot apply tack coat material. Another ground personnel will be responsible for controlling the movement of trucks. It’s crucially important that the trucks stay in order and the next one up is always ready to go. The hotter the asphalt, the easier it is to work with, hence the longer a truck sits, the cooler the asphalt gets. The asphalt is dumped from the truck to the paver where two men control each side. One man is responsible to make sure the joint lines up with the previous paving pull and the other side is responsible for determining thickness, grade, pitch and fall. Accompanying the paver are usually two ground personnel known as “Lute men”. They take direction from the paving foreman and will spread / rake high and low spots out of areas that were just paved but need minor adjustments. Finally, there is the roller man. He is responsible for the compaction of the freshly laid asphalt. Usually this person will work the roller and also plate tampers and hand tampers in the tight areas where pavers cannot go.

I started my career in 1996 working on driveways. I learned how to work with homeowners and how to successfully manage driveway projects. Since then I have completed more than 2,000 driveway projects. Although the majority of my work today is parking lot or roadway oriented, I have never lost touch with my roots and have maintained and kept my Home Improvement License current, ( MHIC # 51204 ). I know driveways and understand driveway issues. I have crews that specialize in driveway installations and repairs. They are also committed to my ideals that “Attention to Detail” is the key to a successful driveway project.
