Learn what causes asphalt cracks and the steps you can take to repair your asphalt pavement.

Commercial asphalt parking lots are especially vulnerable to developing cracks during cold weather seasons. These cracks develop from the excess water vapor in the air, as well as snow, ice, and rain that frequently fall during late autumn and winter. However, if asphalt cracks develop, there are some solutions that PTG Enterprises is eager to provide to retain the integrity of your asphalt pavement. Read on to learn the specific asphalt repair jobs required to fix those pesky asphalt cracks.  (more…)

Crack Sealing: Combating the Effects of Freeze-Thaw Damage

Wednesday, January 28th, 2015

Crack SealingWith the impending snow storm coming through Maryland, it is necessary to prepare to repair freeze-thaw damage to your concrete pavement. Freeze-thaw damage is done when water seeps into small cracks in the pavement, freezes, and expands the crack. The resulting larger spaces in the concrete will then thaw when the temperature goes up, displaying a bigger problem than you had before. Sealing these gaps is a common maintenance activity done by PTG Enterprises.

Crack sealing the asphalt prevents water and other materials from seeping into the cracks. Filling the concrete should be done before it snows or before a rainy season. The idea behind this is that there will be less repair work to complete. If no preventative maintenance is done, larger gaps in the concrete will need to be filled, which is more costly. Filling cracks will happen a few times over the winter since water will sneak through each time there is a snow day.

The Federal Highway Administration did an extensive study on what type of materials should be used to effectively seal cracks in the pavement and to what magnitude these materials should be used. The findings for normal cracks (2.5-5 millimeters) are as follows.

  1. Short-term crack sealing: Rubberized asphalt should be positioned in “Band-Aid” arrangement if the pavement has ordinary cracks, to perform for a term between one and three years. The study also found that this will work with average traffic levels.
  2. Medium-term crack sealing: This time span will be between three and five years, with moderate traffic and two varying types of asphalt. Rubberized asphalt may be placed in the cracks in a recessed “Band-Aid” configuration or a modified rubberized asphalt can be inserted in a simple “Band-Aid” alignment.
  3. Long-term crack sealing: A modified rubberized asphalt sealant is to be used in a simple or shallow recessed “Band-Aid” configuration. This would be for a time span of five to eight years in moderate traffic.

The study revealed that quality control is essential, and crack sealing should be done precisely and carefully. Water that penetrates these normal cracks will soften the stone and shorten the lifespan of the asphalt pavement. More damage can be done if not taken care of such as pot holes; common in Baltimore City. This winter, freeze-thaw destruction will create these large openings and should be fixed as soon as possible.

Crack Sealing vs. Crack Filling: Your Baltimore Asphalt Contractor explains

Friday, February 8th, 2013

As we explained last week, first impressions mean everything in business. Because of this, it is important to keep your parking lot in tip top shape. Still, no matter how much preventative maintenance you perform, your asphalt will eventually crack. The key to preserving your parking lot is to repair small asphalt cracks before they spiral out of control, eventually leading to more serious issues, like potholes or even total asphalt failure occur.

Crack Sealing vs. Crack Filling

There are two primary methods for dealing with asphalt cracks, crack sealing and crack filling. This prevents water and other foreign substances, like sand and dirt, from penetrating the asphalt surface and degrading the asphalt from beneath. Crack sealing and crack filling are the most cost effective pavement repair and maintenance techniques available. But which is better?

  1. Crack Filling: The less expensive of the two methods, crack filling may not last as long as crack sealing.
  2. Crack Sealing: Crack sealing is the more expensive method, but also the more durable method. While crack filling may only last one or two seasons, crack sealing can last up to 8 years or more.

So what matters more to you, initial expense or longevity?

Crack Seal or Crack Fill – How to Decide?

Friday, August 3rd, 2012

When it comes to asphalt pavement maintenance and dealing with cracks, you have two basic options: crack sealing and crack filling. But which is best? Well, that all depends on the situation. So before we get into crack filling vs. crack sealing, we must first address the different types of asphalt cracks.

Types of Asphalt Cracks

  • Transverse Cracks: These cracks are caused by reflective cracks from an underlying layer, daily temperature cycles, and poor construction due to improper operation of the paver.
  • Longitudinal Cracks: These are cracks that are parallel to the pavements centerline or laydown direction and are the result of pavement fatigue, reflective cracking, and/or poor joint construction.
  • Edge Cracks: These cracks appear along the inside edge of a pavement surface within one or two feet and are commonly caused by poor drainage conditions and lack of support at the pavement edge.
  • Seam Cracks: These cracks occur along the paving joints and are typically caused by improper hot mix paving procedures.
  • Block Cracks: These cracks look like large interconnected rectangles, hence their name. Block cracking is generally caused by shrinkage of the asphalt pavement due to an inability of asphalt binder to expand and contract with temperature cycles.
  • Reflective Cracks: These cracks appear when the surface material cannot adjust to the changes in the movement of the sub-surface courses.
  • Alligator Cracks: Alligator cracking is a load associated structural failure due to weakness in the surface, base or sub grade; a surface or base that is too thin; poor drainage or the combination of all three.

When deciding whether crack filling or crack sealing is best, your asphalt contractor will take the expected movement of the cracks in the pavement into carefully consideration.

  1. Crack Filling: Generally, crack filling will be used for non-working cracks with moderate to no edge deterioration.
  2. Crack Sealing: Generally, crack sealing is used for cracks with limited edge deterioration

Experienced personnel – like the ones found at PTG Enterprises – can usually identify the crack type; working or non-working and take the appropriate action.

Crack Sealing: An indispensable pavement protection procedure

Thursday, May 31st, 2012

There is no argument that all asphalt cement (AC) pavements crack. Cracks in asphalt pavements are inevitable. Neglect and lack of proper maintenance lead to accelerated cracking and/or potholing, further reducing the serviceability of the pavement. There are numerous reasons, which can be broadly categorized, in four distinct classes.

  • Pavement Construction: Examples in this category include flaws in the selection of the right type of asphalt mix, poor mix design, engineering defects, unsuitable ambient conditions, etc. If all of these factors meet design criteria, bpoor workmanship may be considered as a cause for premature failure of the pavement.
  • Traffic Frequency & Load: Fatigue cracking and rutting are the two principal considerations in the pavement design process because they are the primary mode of deterioration of asphalt pavements.
  • Deterioration of the asphalt cement binder, primarily due to weathering under the degrading effects of ultraviolet radiation.
  • Climatic conditions, and pavement expansion and contractions due to temperature variations, and freeze thaw cycles.

Once cracks develop, water easily penetrates into the base and sub-base of the pavement and damages the structural integrity of the aggregate materials. Pavement joint and crack sealants are designed to protect the pavement by minimizing water infiltration and by preventing the accumulation of debris. It has been amply demonstrated and documented that sealing cracks in flexible pavements is a sound preventive maintenance procedure, which adds many years to the life of the pavement, especially when used in conjunction with other preventive techniques such as slurry seal, chip seals and sealcoating.

  • Crack sealing is one of the most cost-effective ways to prolong the pavement life, as much as 3- 8 years.

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 Importance of Crackfilling: Don’t Let Your Parking Lot Waste Away

Friday, November 11th, 2011

Cracks in your asphalt parking surface are an immediate cause for alarm. If left untreated, cracks will allow water to penetrate the surface, softening the stone base and leading to alligator cracking, spider webbing, pot holes and other forms of parking lot degradation. And as the weather quickly begins to cool this time of year, these problems are compounded. The freezing and thawing cycle can turn even the smallest of crack into a big problem.

If you don’t attack cracks while you have the chance, you may find yourself paying for premature and costly resurfacing. Crack filling may be your best solution. It can reduce pavement deterioration by restricting water penetration into the base and sub-base layers.

Crack sealing/crack filling of your asphalt pavement – driveways, parking lots and roads – is a necessary preventative maintenance measure, extending the useful life of your pavement and yielding long-term financial savings.

However, to experience the best results possible, you should leave your asphalt maintenance to a proven pavement professional with a track record for quality work, like PTG Enterprises, Inc.

“Properly crackfilling your parking lot is the single best thing you can do to maintain its life,” says PTG Enterprises owner, Patrick T. Gillen III. “Left untreated, small cracks will allow water in and become big cracks eventually penetrating through the asphalt and contaminating the sub-grade.”

The Basics of Crack Filling

Asphalt Crack Sealing

Thursday, September 29th, 2011

Asphalt cracks do not form over night. They slowly grow, sneaking up on you until that tiny crack becomes a major problem. Asphalt cracks slowly elongate and widen during weather changes such as freezing and thawing or intense periods of heat.

However, if you monitor your parking lot carefully and catch these tiny cracks early enough, you can patch the problem before it gets any worse.

Asphalt crack sealing is the solution. Some fillers require special equipment for heating and applying and some are ready to go out of the box or can for the do-it-yourselfer. But to get that professional look, you should probably use a professional asphalt contractor, like PTG Enterprises.

They will be able to properly apply your sealcoat, ensuring your parking surface remains crack free for as long as possible. They will also be able to answer any questions you may have, such as…

What is Sealcoating?

Sealcoating is a widely used and accepted preventative measure that helps safeguard a parking lot against the harsh effects of gas, oil, salt, weather conditions and oxidation. This coating will significantly reduce the impact of these harsh effects. When applied properly, a sealcoat cures on your parking lot leaving a fresh black finish. There are many ways that sealer may be applied and material mixes may vary as well.

How often should you have your parking lot sealcoated?
One of the most important things you can do to ensure a long life for your parking lot is to fill cracks and seal it every two years.

A newly laid asphalt parking lot should be sealed within the first 12 months. Because of the ever increasing costs of asphalt, many business owners now seal every other year. This has proven to be an excellent approach to avoid expensive repairs and maintain an aesthetically pleasing parking lot. There are many factors to consider when deciding how often to sealcoat.

Crack Sealing versus Crack Filling

Thursday, July 28th, 2011

Your pavement will eventually fail. It doesn’t matter how well you maintain your paved surface, it will eventually deteriorate and crack. However, how you deal with those cracks will determine how long your pavement will last. Sealing and/or filling cracks in existing pavement is the single the most effective procedure that can be performed to extend pavement’s lifecycle. This will prevent water and other foreign materials – sand, dirt, et.c – from seeping down into the asphalt where it can cause major distress and failures by weakening the base and sub-base.

This article from PaveManPro.com explains how filling or sealing pavement cracks is the most cost effective way to extend the life of your asphalt pavement.

Crack filling and crack sealing, while similar in nature, offer very different benefits.

Crack filling is less costly and will require less initial investment, but this solution may only be a temporary fix. Once the crack begins to move or expand, the crack filling material will lose its effectiveness and the crack will need to be re-filled. For this reason, crack filling is more effective in milder climates with less temperature change.

Crack filling materials include liquid asphalt, asphalt emulsions and cutbacks.

Crack sealing is a more costly option, but provides a longer life expectancy than crack filling – lasting 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.

Crack sealing materials include asphalt rubber, rubberized asphalt, low-modulus rubberized asphalt and self-leveling silicone.

So explain your situation and budget to your pavement specialist and come up with a solution that meets your needs and your budget. If you have any questions, contact PTG Enterprises aka My Pavement Guy by calling 410-636-8777 or click here
