How to Know When to Seal Coat or Repave Asphalt Pavements

What is the most cost-effective resurfacing solution after repairing cracks, potholes and depressions in asphalt driveways and parking lots


By Jeff Lax

When it comes to old, worn asphalt driveways and parking lots, commercial real estate owners, property managers, and even owners of single-family homes struggle with the same questions: Do we repave or sealcoat after making repairs to cracks, potholes, and depressions? What is the most cost-effective and durable solution?

The industry has debated this issue for decades, and what has been learned is that each option has lasting, dramatic effects and that they actually complement one another. That’s the information pavement maintenance contractors need to convey to their clients who are trying to decide which pavement maintenance option best suits their needs and property.

Sealing

Sealcoating is one of the most important steps to protecting an owner’s investment in an asphalt driveway or parking lot. Sealers consist of emulsions that combine asphalt or refined coal tar with clays, mineral fillers, and water. Once applied, the water evaporates and the emulsion hardens to form a protective coating. It also becomes a beautiful black surface that adds curb appeal, giving a single-family home, multi-family residence, or commercial or industrial property a polished look. Industry experts agree that driveways or parking lots lacking the sealer can generally last only five to six years before the beginning stages of breakdown.

Initial sealing should occur six to 12 months after the asphalt surface is laid to allow the pavement to “cure” so oils can escape and the surface becomes ready for sealer. The initial sealer application forms a barrier to prevent water penetration and to inhibit deterioration of the asphalt binder by oxidation and over-drying.

As unprotected pavement ages, the asphalt binder hardens, losing flexibility and becoming increasingly brittle. Ultraviolet rays from the sun break down the carbon bonds in asphalt, further weakening the pavement. Also, daily and seasonal cycles of heating and cooling cause the pavement to expand and contract. These stresses eventually exceed the pavement’s ability to flex, and cracks form. If water seeps into the cracks and freezes, the cracks expand, allowing more water to penetrate, making the cracks wider and deeper. This cycle leads to accelerated deterioration of the parking lot surface. Early sealcoating can prevent all these preliminary dangers to the life of the asphalt.

Sealer is typically the most cost-effective solution and should be reapplied every two to three years as preventative maintenance. In fact, several government and Asphalt Institute studies have shown that neglected asphalt pavement can cost up to five times as much to repair as asphalt that has had a regular maintenance program, including sealcoating.

Pavement maintenance begins by filling cracks, patching deteriorated areas, and cleaning (and possibly priming) oil-saturated spots on the pavement surface. The asphalt also must be cleaned of dirt and debris before sealer can be applied.

While some homeowners sealcoat their driveways themselves, professional contractors not only apply a high-quality sealer material but also have professional equipment such as crack cleaners and power blowers that often enable them to perform a longer-lasting, high-quality job. Plus, professional contractors can handle other pavement repairs that a homeowner won’t be aware of, so property managers at any level will be best served by hiring a pavement maintenance professional to handle their pavement.

Repaving

Repaving is the only decision for driveways or parking lots that have severe deterioration, deep wide cracks, subsided depressions and numerous potholes.

An asphalt overlay consists of a compacted layer of one-and-a-half to two inches of hot mix asphalt being placed over the existing asphalt, essentially giving the driveway a new surface. Just as with sealcoating, the first task is repair of existing pavement. Areas, where the pavement surface has slumped, indicate failure of the stone foundation supporting the pavement. These areas require digging out existing asphalt, and repair and compaction of the stone base with new material before patching with asphalt mix to prevent trouble spots from returning after repaving. Then an overlay is placed over the old surface. No sealcoating should be added for six months to a year, just as with any newly constructed pavement.

And while an asphalt overlay can begin to deteriorate within five to six years without maintenance, it could last up to 25 years with regular upkeep. The upside to installing an overlay is the pavement has a renewed wearing course, providing a pliable, flexible surface. Also after the overlay, the maintenance program can start over, leading to a virtually brand new drive or lot. However, extreme weather, heavy loads, and shortcuts during construction could lead to premature wear and failure. The downside of repaving is that it is expensive (typically thousands of dollars more than sealing). Plus, if the original asphalt isn’t properly cleaned and prepared, cracks and uneven sections may return, as well as other problems that may not have previously existed such as delamination of the overlay because of poor adhesion to the old pavement.

What’s Better for your customer?

The amount and regularity of repaving will differ from climate to climate, and even when asphalt is maintained properly an asphalt overlay will be needed every 20 to 25 years.

Regardless of whether you repave or repair, sealcoating is one of the most important aspects of any pavement maintenance effort as it protects asphalt from weathering and degradation and extends pavement life. Without sealer, the asphalt could require an overlay in as little as five to six years, costing thousands of dollars. When comparing costs, industry experts believe the best investment a homeowner or commercial property owner can make is a well-tailored maintenance program that includes regular sealcoating.

Benefits of Installing an Asphalt Parking Lot for Your Business


If you are a business owner, chances are that you have given the interior of your business more weight in terms of finishing and overall appeal while you have neglected the surrounding areas. Even then, you will be surprised to learn how important facade is when it comes to attracting customers.

As such, it is advisable to pay attention to the exteriors, such as driveways by making them appealing to the eye. In most instances, the majority of residential and commercial driveways are finished with concrete or asphalt. Asphalt is particularly a preferred choice for many people, as it is about 30-40 percent cheaper compared to concrete.

The benefits of asphalt are much greater than concrete. Here are some reasons why asphalt driveways are a must for your business:

Flexibility – When compared with concrete, asphalt is more elastic and able to withstand severe weather conditions. The liquid asphalt component allows asphalt to remain flexible, and better able to handle expansion and contraction.

Resilient – Asphalt is best equipped to withstand wear and tear resulting from high traffic that is common in many commercial establishments. Furthermore, it requires less maintenance making it an ideal choice of materials for your surface.

Aesthetic value – Not only does asphalt have a smooth surface, but it also looks cleaner. Asphalt can also be freshened up with a coat of asphalt sealer, restoring its original appearance. In addition, it is liquefied making it customizable. Thus, you can easily stamp in designs as well as decorations.

Environmental friendly – Asphalt driveways contain reclaimed asphalt pavement (RAP) that is 100% recyclable. RAP refers to old asphalt that is usually milled from pavements that have reached the end of their service life. Asphalt binder is used in the RAP meaning that a minimal amount of virgin asphalt and petroleum are used. Consequently, less mining aggregates are used. Other environmental benefits include cooler asphalt temperatures and reduction of storm system basins. Moreover, when in its porous form, asphalt requires less energy for manufacturing, significantly reducing odor, emissions as well as smoke.

Economical – Asphalt paving is usually less costly upfront compared to concrete paving. In addition, choosing asphalt for your driveway is cost-effective in the long run. That is, it reduces the overall lifetime cost of a paving project. Asphalt helps to reduce the demand on storm sewers effectively eliminating some of the local government impact fees. Apart from a quick installation that allows traffic to return in the shortest time possible, the long-term repairs and maintenance costs of asphalt are also low. On the other hand, concrete takes long to lay and set, this can result in loss of business. In terms of repairs, a crack on asphalt can be repaired inexpensively and quickly.

Versatile – The installation of asphalt driveways can be done over time depending on availability of funds. Thus, when traffic loading increases, installation can be done at night or during off-peak times when there is minimal disruption of traffic. Asphalt layers may be on a needs basis.

Safe – Asphalt driveway construction can only mean shorter lane closures translating to more safety for vehicles as well as workers within the work zone.

When completed, asphalt driveways offer other benefits over concrete driveways that include the following:

  • They are skid resistant as they offer high friction due to the use of durable aggregates.
  • The surface is smoother compared to cement.
  • The surfaces greatly reduce the degree of spraying and splashing during storms. This improves driver visibility.
  • The black asphalt surface also aids in a visible delineation of pavement markings and lanes.

Investing in an asphalt driveway is a good move as the benefits far outweigh the initial investment. If anything, asphalt driveways will attract potential customers to come to your business where they can engage you more thus, adding value to your business.

How to Keep Asphalt From Deteriorating: Sealcoating Your Paved Driveway or Parking Lot Can Help


When you're spending the money to have your driveway or parking lot professionally paved, you don't want the asphalt to deteriorate any sooner than necessary. Sealcoat the surface to protect your walking and driving areas from wear and tear.

Have you noticed cracks or holes forming in your asphalt driveway or parking lot, thanks to years of car and foot traffic? Or are you laying down new pavement and want to make it last as long as possible? Professional pavers employ a process known as sealcoating to lengthen the life of an asphalt surface. Sealcoating will not only make your driveway or parking lot more durable but will also help it maintain its clean, smooth look in the face of repeated use. Contact a paving contractor in your area to discuss whether sealcoating is right for your new or existing asphalt surface.

How It Works

As tough as it is, asphalt can be damaged by sun exposure, excessive rain, ice, and temperature changes. Years of gasoline and oil drippings from cars can also cause surface deterioration. Not only will deteriorating asphalt fade from a crisp black to an ugly gray, but it can also become rough and crack open-and water accumulating in pavement cracks or holes can lead to further damage. Sealcoating a pavement area approximately 60 days after the initial asphalt application will protect it from weather and car fluid damage in the years ahead, lengthening the overall life of your paving. Driveway sealer is composed of a coal-tar emulsion, sometimes fortified with rubber or silica sand for increased durability. A paving contractor will apply sealer either by brush or by spraying it over the area; the method may depend upon the size of the area to be sealed, or upon the individual contractor's preference.

Repair and Resealing

If you want to seal a driveway or parking lot that is several years old and has already begun to deteriorate, the paving contractor must first repair the damaged asphalt. This may involve filling any holes or cracks in the pavement, as well as smoothing out rough areas. It's also a good idea to clean up any oil stains before applying sealcoating, as once they're sealed in, those stains are permanent. In general, you should apply a new coat of driveway sealer every two to three years. Resealing and minor repairs will almost always be less expensive than having to completely replace the pavement.

Benefits

Having a sealed driveway or parking lot surface has benefits far beyond the money saved on re-paving. For starters, the smooth, sealed finish will be easier to clean than cracked, stained asphalt, enabling you to keep your property looking its best. Even more importantly, sealed pavement is safer to walk and drive on. Large cracks and holes can pose a tripping hazard for individuals of all ages. Meanwhile, brittle, deteriorating asphalt can form potholes, which can prove hazardous to drivers. Properly maintaining your driveway or parking lot area by sealcoating the asphalt will protect both your investment and the individuals who use the space. Contact a parking lot or driveway paving specialist near you to learn more about your sealcoating options.

Asphalt Paving and Sealcoating - The Hard Facts of Asphalt Repair


Asphalt Pavement begins to deteriorate as soon as it is laid down. Fuel and lubricants dissolve it, water softens it and sunlight accelerates oxidation to break down the binder. Unsealed blacktop can lose half its thickness in twenty years.

Within a year or so, the original black color begins to pale. The binder asphalt begins to lose plasticity. Hairline cracks form. After five years the entire thickness has oxidized and become brittle. The color is light gray. By the eighth year, cracks extend clear through the pavement. Material is loose on the top. The base fails as water soaks through. Within a year or so, areas with alligatoring cracks become potholes. After fifteen years, the entire surface will have broken up.

DOES YOUR ASPHALT PARKING LOT NEED REPAIRING?

"IMPORTANT REPAIR TIPS"

When was the last time that you thought about your asphalt parking lot and its upkeep? This is the same place where you park your car everyday and the entrance to your home or office. It is a known fact that first impressions are lasting and this is true for your clients or friends when they drive into your parking lot. They are either encouraged to come and visit you or turn around and drive away, depending on the look of your surroundings and yes, this includes your parking lot!

We will first start with a few statistics of asphalt parking lot upkeep. If your asphalt is sealcoated every three years, it will have an average life span of thirty years! If your asphalt is not sealcoated, it will have an average life span of fifteen years. Asphalt repairs can cost as much as much as $6.00 per square foot. Sealcoat can be applied for as little as 8 cents per square foot. It doesn't take a genius to figure out that sealcoating your asphalt every three years prevents major repair costs in future years.
To determine if your parking lot needs any repairing, go take a look at it. Here are a few signs to look for:

1. Rough Asphalt - Is the surface of your asphalt not smooth? Can you see the tops of the rock or aggregate showing through? Are pieces of rock coming out of your asphalt? These are all signs that you need to have your parking lot sealed and repaired. Excessively rough areas usually require installing a new asphalt skin patch prior to sealcoating so that the sealcoat will last when being applied to these areas.

2. Cracked Asphalt - Do you have cracks appearing in your asphalt? These can be caused by either excess water under the parking area or lack of proper sealcoat maintenance over the years. These areas can be repaired by either rubber crack filling or removing and replacing them with new asphalt depending on how severe the damage has been. Cracks can also be caused by tree root pressure.

3. Worn Stripes - Is your parking space striping and stenciling looking worn? Are the old lines appearing through your old sealcoat? These are signs that it is time to sealcoat and re-stripe the parking area. Striping is the most noticeable part of the parking lot and it is very important that you have a neatly done job.

When choosing an asphalt contractor to do the work, make sure you ask for references to previous jobs that were completed. Call those people to see if they were satisfied with the asphalt contractor's work. Remember, price is not everything! Some contractors use better materials and do better work than other contractors.

As a rule of thumb, make sure that the asphalt contractor dilutes the sealcoat with a maximum of 10% water. This way you will get a thicker coat of sealer- and that will last a long time. When your asphalt is severely cracked (alligatored) and needs to be removed and replaced with new asphalt, make sure that the new asphalt is installed to a depth of at least 3 inches. This will usually give you a good solid patch. Remember, first impressions are lasting. People like a clean and well kept parking lot.
Stop... Think About Your Asphalt Driveway!

When was the last time that you thought about your asphalt driveway (the path that leads to your humble home and the place where you park your car)? This article will give you the in's and out's on caring for your asphalt driveway, whether it is new or otherwise.

If you have an asphalt driveway, seal it! The sun and water are your driveway's worst enemies. If you do not regularly seal your driveway, the surface will become rough and the asphalt will start to crack, causing further damage. If your driveway is older, has started to get rough, and is forming small cracks it is even more urgent that you seal it to protect your investment.

If you decide to do the job yourself, you can buy asphalt sealer in five-gallon containers at any of your local lumber companies or home improvement stores. You also need to purchase a special sealer broom to apply the sealer and a paintbrush to cut in along walls and tight areas. Applying the sealer to your driveway can be tricky. You need to apply it in even brush strokes. When it dries it will look just the way you brushed it on. The sealer will dry very fast so you need to work very quickly.

There is a big difference between the sealers that YOU can buy and the sealers that are used by asphalt contractors who seal driveways for a living. The sealers that the asphalt contractors use contain silica sand and/or slate which allows the seal to last about twice as long as the kind purchased at the store. The asphalt contractor uses a mixer machine to keep the aggregates agitated. Otherwise, it would stick like lead to the bottom of the container. If you seal your own driveway, it's good to do it about every year. If you have a contractor do it, have him seal it every three years.

If your driveway is older and has some cracks, it is recommended to fix them before any more damage occurs. Asphalt cracking is caused primarily by the effects of the sun and by moisture. Proper attention to cracks will prevent your driveway from breaking down further and will double the life of your asphalt. If you seal your own cracks, make sure that you buy a crack sealer that has rubber compounds. This type of product allows the crack to expand and contract without breaking open. Rubber crack sealer will flex with the movement of the asphalt and will help prevent water from seeping into the crack. Always seal the cracks before you seal your asphalt driveway. If you hire a contractor to seal your cracks, make sure he uses a rubber based sealer. (Some do not!)

Your driveway is an investment. The better you take care of it, the less it will cost you in the long run. The best thing about a well-maintained driveway is that it looks great and enhances the look of your home.

Does Your Parking Lot Sing the Trash Truck Blues?

I can't count the amount of phone calls that we have received from irate apartment owners. The conversation usually starts out by the owner saying, "Those darn trash trucks are ruining my asphalt parking lot. There are cracks as far as the eye can see and the ground is starting to heave. I'm afraid that one of my tenants is going to fall and brake a leg." As you know, these are all very valid concerns.

Trash trucks are the leading cause of asphalt parking lot damage. Generally, parking lots are not constructed to handle heavy truck traffic. Usually the base material (decomposed granite) on older parking lots has not been installed or has been installed in a very thin layer. The pavement that is laid on top of this base is only as strong as the base material. This can cause premature stress on the asphalt pavement when a heavy truck passes over the surface.

Think about it! One pass of an 18,000 pound load on a single axle truck has the same effect on an asphalt parking lot as 9,600 automobile passes. What does your local trash truck weigh when it is full of wet, smelly, compacted garbage? It usually weighs more than 18,000 pounds. If your trash truck shows up once or twice a week, the damage load can be the equivalent of between 10,000 and 20,000 cars. That's a lot of traffic!

By now, you are probably wondering what you can do about this problem. Depending on your property, there are several measures that you can take to help repair the current damage and limit future trash truck damage.

The first thing that you should do is to repair the damage that the trash truck has caused. This usually requires saw-cutting and removing the damaged asphalt and replacing it with new asphalt to a depth of not less than four inches. The new asphalt patch should always be deeper than your existing asphalt.

If your trash truck damage is not too severe, you can have your damaged areas overlaid with a new layer of Petromat and asphalt. This is less expensive than removing and replacing your asphalt. Petromat is made out of fiberglass and is designed to help prevent your old pavement cracks from coming through the new layer of asphalt. The new layer of asphalt must be a minimum of 1.5 inches deep over the Petromat for maximum effectiveness. Since the level of your existing parking lot will be raised by Petromat patches, you have to make sure that water puddling will not become a problem.
After your asphalt patches have been completed, you should sealcoat and re-stripe your parking lot to keep it looking nice and to help keep your patches tightly locked and waterproof.

The second thing that you should do is to figure out how to help prevent the damage from occurring again! One way to do this is to install concrete pads where the trash trucks cause the most damage. Usually this is in the FRONT of your trash dumpsters. The concrete pads I see are usually too small or are in the wrong location. You need to make sure that the concrete pad is longer than the trash truck and is installed where he stops and picks up your trash dumpster. The reason that this area is subject to the most damage is that the trash truck is stopped causing the most down pressure on your pavement. The truck also shakes and shudders when it is dumping your dumpster which causes additional stress on the area. The concrete pad should be a minimum of six inches deep, using steel rebar and 3,000 PSI concrete.

The third thing that you should do is to review the existing locations of your trash dumpsters. Closer is better! Some apartment properties are situated so that the dumpster areas can be moved closer to the street. Just remember, the closer to the street that you can locate your trash dumpsters, the less it will cost you in parking lot repairs. In most apartment owner cases, this means thousands of dollars $$$ in long term savings.

Explaining Tire Scuff Marks on New Asphalt Pavement


Did you just have your driveway repaved with a brand new asphalt overlay? Or maybe a new layer of sealcoat? Or perhaps you are a company owner that just finished construction on a new commercial parking lot? Either way, you may start to notice tire marks as business or traffic picks up. Tire scuff marks are a common occurrence to newly-paved or seal-coated asphalt, and for many reasons. Before you pick up the phone to have a word with your paving company, it is encouraged to investigate a bit further, and find out why tire marks appear on newly-paved asphalt in the first place. Continue reading to learn what causes asphalt tire scuffing, and gain a better understanding of what to expect from your pavement.

Tire Scuffing

Fortunately, there is no need to panic about tire marks since they will eventually fade after a few months. There are several reasons why freshly-paved or seal-coated asphalt is subject to tire scuffing, but they can all be narrowed down to five specific ones. If you have questions about any of these causes, feel free to contact your paving company afterwards to discuss them in detail. They can give you expert information, answers, and advice regarding asphalt paving, sealcoating, and more. For now, start by reviewing the 5 most common factors that cause asphalt tire marks, below.

1. The Age of Pavement - New pavement, or pavement with a new layer of sealcoat, is more susceptible to tire scuff marks since it is still soft and malleable. As it hardens, tire marks begin to disappear. Asphalt requires flexibility to maintain maximum durability, but as it ages, it loses this attribute.

2. Outdoor Temperatures - The time of year affects the rate at which asphalt hardens after being laid. Hot weather will slow the curing process, keeping pavement soft and flexible a little longer than usual. And we already mentioned that soft pavement allows for tire marks. This is why most paving jobs are carried out in the fall and winter, when temperatures are cooler and pavement cures faster.

3. Vehicle Weight - New asphalt pavement that experiences frequent traffic from heavy vehicles, like trucks, buses, and vans, is more susceptible to tire scuffing. Stationary 180-degree turns, sudden braking, sharp turns, and trucks with power steering are common causes for tire marks..

4. Type of Tires - The type and size of tires play a major role in producing tire scuff marks in new pavement. Most standard tires can and will cause this to happen, but tires with aggressive tread patterns, steel-belted radial tires, and off-road trucks and SUVs will guarantee it.

5. Type of Asphalt - The type of asphalt will also influence the likelihood of tire scuffing on new pavement. Course aggregate is less likely to scuff, whereas, a thin sealcoat will.

Asphalt Pavement Checklist for Facilities Maintenance


Most property managers have facilities maintenance checklists for the interior and exterior of their buildings including the landscaping and parking lots. On a regular basis, the items on these checklists are reviewed; repairs are noted and performed to keep the property in pristine condition. In this article, we'll focus on the items on those checklists that refer to the upkeep of a facilities parking lot.

Asphalt Pavement Checklist

1) Asphalt Sealing

Why should I sealcoat my asphalt?

Sealcoating asphalt pavement protects the surface of a parking lot from oxidation and damage from oil, gas, and salt. It also minimizes the need for asphalt repairs by weatherizing the surface which helps prevent water from being able to seep into cracks. If not properly sealed, pavement starts to unravel and potholes form.

After installation, asphalt should be sealed between six months and a year and then approximately every two years after depending on weather conditions, traffic patterns, and wear and tear.

2) Crack Filling

What should be done about cracks in your asphalt?

Each year, your parking lot should be inspected for asphalt cracks. Sealing cracks in asphalt prevents moisture from degrading the structural components of the surface. For asphalt cracks that are smaller than a quarter of an inch wide, sealcoat can be used. However, cracks that exceed these dimensions will require your paving contractor to apply a crack sealer.

To perform this necessary maintenance, the crack should be cleaned of all debris, including loose asphalt, vegetation, and other foreign objects. Once the crack sealer is applied and has set, the pavement should be properly sealcoated for ultimate protection.

3) Pothole Repair

Why do potholes form?

Potholes occur when water permeates asphalt pavement through a crack in the surface. Combined with wear and tear, the soil beneath the crack will soften, and eventually create a depression. Over time, the asphalt will unravel and break down into its sub-particles - gravel, sand, and stones.
In northern states, asphalt patches applied in winter months typically do not hold up as well as potholes repairs that were made during warmer months. Due to the mild temperatures in Florida, pothole repairs can be completed almost year-round.

4) Asphalt Pavement Replacement

When should I replace asphalt pavement?

Often it's difficult for someone without years of asphalt pavement experience to determine just by looking at a parking lot whether it can be repaired or, due to the cost of repairs, it is a better financial decision to replace it entirely. That's where the professionals come into play.

Over time, even a parking lot that has been well-maintained over the years will eventually deteriorate and need replacement. Asphalt experts will analyze the entire paved area for the current conditions. A few other factors that need consideration are drainage, traffic load and any issues caused by landscape - such as a large tree with roots wreaking havoc under a pavements surface.
