Why You Sealcoat Your Asphalt Driveway
Do you own a commercial property with an asphalt parking lot or a private residence with an asphalt driveway? If you do own or manage some type of asphalt pavement you will need to take proper care of the surface. In the long run, it will save you time and money. While taking proper care of the pavement does have some cost associated with it, it is not near the cost of having to later fix any damage that has already occurred to the asphalt. If you notice that you already have potholes or large cracks starting to appear, it is in your best interest to address the issues as soon as possible.
The first step in maintaining an asphalt pavement is crack sealing, crack sealing prevents water from entering the pavements sub-base through cracks in the asphalt surface. If these cracks are left untreated they will eventually turn into potholes and destroy the asphalt surface and the base beneath the asphalt. Once you allow this to happen there is no maintaining the asphalt, you are now looking at having to replace the pavement. It is important to clean the cracks thoroughly before filling them. You will need to clean out any and all debris. This will help ensure the material adheres to the surface correctly. Once all of the cracks are completely cleaned and filled with the asphalt fill material, water will no longer be able to enter beneath the pavement down to the sub-base material. By using this technique you have increased the lifespan of your asphalt pavement in the most beneficial and cost-effective way.
Sealcoating your parking lot is definitely a great way to protect your asphalt surface as well. Sealcoating your asphalt will help protect against the suns ultraviolet rays and also keep any water from entering small cracks in the pavement. The asphalt sealcoating material needs to be mixed to the manufactures specifications. The sealcoat material needs to be applied in two coats. The first coat of sealer should be applied with a squeegee to push the sealer into the cracks of the pavement. The next coat may be applied using a spray technique. The spray of the sealcoat ensures a uniform coat over the entire asphalt surface. Be sure to allow the proper drying time of the sealcoat before using the asphalt pavement. Sealcoating of the asphalt surface should be done as necessary to help ensure the lifespan of your asphalt surface.

Parking Lot Striping and Maintenance Increases Customer Safety
In business, it is important to always put your best foot
forward, and that step can start with fresh parking lot striping. Fresh
paint provides a good first impression for arriving customers. Faded and
cracked lines, potholes, and crumbling chocks are not only an eyesore,
but can also be a safety hazard as well. To ensure customers can park
their cars with ease and navigate the car park without any confusion,
regular maintenance is crucial.
Clear parking lot striping will not only help visitors navigate easily, but well-planned spacing can also help maximize a small area, squeezing in extra spots for cars so that you don't unintentionally lose business. Most car parks are also required by local regulations to meet certain codes which include a specific number of designated handicap spaces for disabled individuals (how many will depend on the location and size of the area). These will require an extra wide border to be clearly marked, allowing for room to remove wheelchairs or other necessary mobility devices. Codes may also require specific stenciling and marked fire lanes.
If the area is jointly operated by several businesses, it can be helpful to designate specific spots directly in front of doors exclusively to one shop. This is particularly useful for quick-stop stores located next to businesses with longer transactions such as restaurants or movie theaters. Keeping a few spaces free and marked for fifteen minutes or less is another way to keep traffic flowing, turning away fewer customers during peak periods. Spaces can be stencil-painted and bordered in a different color to distinguish it from others.
Proper parking lot striping is also a valuable safety tool that can help you cut back on collisions, slip and falls, or other potential hazards. In addition to keeping the paint fresh and direction arrows clear to improve traffic flow, consider re-paving the entire car park if it is extremely damaged. Large holes and cracks can not only damage vehicles, but people can fall and hurt themselves. And if it happened on your property, you may have a lawsuit on your hands. Smashed chocks are another common problem that is often overlooked. Chocks are the bumpers located between spaces or in front of sidewalks to prevent vehicles from moving too far. Over time, the constant stress from car bumps, or even just a single hard hit can result in them cracking and shifting. The rubble left behind can be dangerous to pedestrians and cyclists.
Parking lot striping professionals generally offer several other benefits in addition to their painting skills. Included in their services are often a cleaning of the area using power washing to lift and blast away long-standing grime, a basic warranty covering unexpected fading or stains for the first few months or longer, and help re-planning the area if needed. Most paints are fast-drying, so you won't have to worry about closing off the area for long. Always choose a company that is licensed, experienced, and fully insured so that you will receive quality work that you can depend on.

Will I See the Asphalt Repairs When They’re Done?
One of the most common questions that I'm asked is, “Will I see the repairs when they're done?” My answer is always the same - yes. It's impossible to match old asphalt using new asphalt, even with infrared repairs. How well a repair blends with the surrounding asphalt depends on one main factor, how many times the surrounding asphalt has been sealed. Each time you sealcoat your asphalt, the voids between the aggregate get filled in a little more. The more times a driveway has been sealed, the less texture it has, leaving little chance it will match up with new asphalt that has more texture. Just imagine your old driveway next to a new driveway, that's the difference you will see.
A follow up question I hear a lot is, “Won't it blend in after I sealcoat?” It will blend better with a sealcoat (same color), but the textures will still be different and the repairs will be visible. Asphalt surfaces that have only been sealed a few times can eventually blend in pretty well with a few sealcoats, over a few years. If a new driveway is what you're looking for, you’ll need a paving company that can give you a new driveway. Infrared repairs are a nice option if a large portion of your asphalt is in good shape and you can accept that the repairs will not be invisible.

When Should I Restripe My Parking Lot?
Typically it's a good idea to restripe your parking lot every 18 to 24 months, depending on your location and climate. Restriping your parking lot enhances curb appeal and the safety of your customers.
If you own a parking lot, it is important to make sure that the lot is always in the best shape possible, naturally. You want it asphalt to be intact and sealed, and you want the stripes and spaces in the lot to be clear and bright. It offers a range of benefits for your parking lot and business. There are many times that you should consider restriping the parking lot.
Typically, it is going to be a good idea to restripe about every 18 to 24 months, at least. However, it will also depend on the location of your business, and a host of other factors.
For example, if you live in a climate where it snows, you probably rely on snowplows to come along and remove the snow from your parking lot. While this is beneficial to ensure that your parking lot is up and usable for the customers, it also means that there is the potential for those plows to scrape away some of the lines in the parking lot. In those cases, it is generally going to be a good idea to restripe annually. After the last snow of the year has gone, set up an appointment to have your parking lot restriped or paint new parking lot lines yourself.
After Sealcoating
If you have had asphalt repairs and sealcoating on your parking lot, then you are certainly going to need to have restriping completed before you can open up the parking lot to your customers. The sealcoating is going to cover up the lines, so once it has dried, you will need to make sure that you have someone come out to add the stripes to the parking lot.
Keep Up With the ADA Code
In addition, you will want to be sure that you keep up with the requirements from the American Disability Act. This will indicate what you are going to need in terms of disabled parking spaces, and you need to be sure your parking lot is fully compliant. In some cases, this might mean having a striping company come out to your parking lot as soon as possible to make the updates to help bring the parking lot up to code.
What Are the Benefits of Regular Restriping?
For starters, you want to think about the curb appeal of the property. Having nice clean and easy to see lines in the parking lot is going to make it look better. We’ve all seen old parking lots that don’t have lines or whose lines have faded over the years. They look neglected. If the owner doesn’t care enough to take care of the parking lot striping, it typically means they do not care much about the buildings and stores that are in the parking lot, or the rest of the upkeep they should be taking care of.
If you are planning to resell the property, not painting the strips and improving that curb appeal is going to hurt the resale value. It might seem like a small thing, but it is very important. It will help to show that the business is well cared for, and that can help to make getting a sale easier.
In addition, there is a safety factor that you have to think about when it comes to the parking lot. If the parking lot has not properly been striped, it means that people are not going to know where to park properly, and this can cause confusion and an element of danger in the parking lot. You need to have clear parking spots and directional lines in your parking lot for the safety of the vehicles and drivers, as well as pedestrians that are walking through the parking lot.
And if you've ever been in a parking lot in a snowstorm, you know that not being able to see the parking lot lines means people put a lot of space between their cars and you get fewer of them in a lot. If you have a busy business, using every parking space affects your bottom line: make it clear to your customers where they can park.
High traffic parking areas often add reflective glass beads in the stripes, which are going to be easier to see in the evening when headlights hit them. These can add an extra layer of safety, and they can be a nice solution for many types of parking lots, including airports and hospitals.
Get In Touch With Professionals Or Do It Yourself
Now that you know why and when you should be restriping your parking lot, it is time to get in touch with a company that can take care of the restriping for you. Always make sure that you are dealing with professionals who have the right equipment and who understand ADA compliancy. Many times, the same company that you hire to take care of the asphalt repair and the sealcoating will be able to offer the restriping services you need. It could be a good idea to have one company that can take care of everything needed for your parking lot.

3 Types of Damage Asphalt Sealing Prevents
Asphalt sealing is an important part of maintaining a driveway or parking lot made of this material. It should be performed every two to three years to protect the pavement from developing damage that could shorten its life span. If you miss this maintenance, you could develop one or more of the issues below.
What Can Happen When You Skip Asphalt Sealing
1. Freeze-Thaw Expansion & Fracturing
The winter can be absolutely brutal on asphalt, particularly due to the freeze-thaw cycle. This occurs when water seeps down into the pavement, freezes, and expands — resulting in cracks. As the water thaws, it will then creep even deeper into the material, repeating this process and leading to numerous fractures. Asphalt sealing prevents this by covering any small cracks in the material and keeping water out year-round.
2. Sun Drying
asphalt sealing cookeville tnWhen the sun’s harmful ultraviolet rays beat down on asphalt, they damage it in a way similar to how they affect your skin. The chemical bonds in the pavement begin to deteriorate, leading to cracks and other damage on the surface. Asphalt sealing prevents this by covering the blacktop in anti-oxidation additives and other aggregates that act as a barrier.
3. Surface Softening
Since asphalt pavement is predominantly used by vehicles, it will most likely experience some auto fluid spills. When oil, gas, and similar liquids fall onto the surface, they will be absorbed by the asphalt and cause it to soften. While these spills can be easily cleaned up in most cases, overtime they can result in cracks or a deterioration of the aggregates comprising the blacktop.

Asphalt: Best Choice for Driveway Pavers
Oftentimes, when you travel, you see well-paved roads which make the trip a whole lot easier and comfortable. Ever wonder how these roads are built? Well, it is apparent that most of the roads around the country are part of an asphalt paving project that was completed sometime in the past. It's not surprising that among numerous choices for paving, asphalt is often the top and the most popular option. It clearly differs from other paving materials, such as concrete, simply because it's more versatile and economical too. Definitely, it is among the most common substances in use today. Not only is it used in paving roads, parking lots and driveways; it is also used in coatings, batteries, adhesives and asphalt shingles in roofs.
Like other paving materials, asphalt requires a specific process and skilled workers to apply the material properly to achieve a smoothly paved surface. It is also durable and waterproof in nature. Apart from being a bit messy, it is relatively easy to pour, flatten, shape and finish. It's notable that it hardens quickly, too. Ideally, it is used in regions where the weather is dominantly cold throughout the year. This would prevent the paving material from softening, which happens only if used in places with extremely hot climates.
A good number of homeowners choose to have asphalt in paving or repaving their driveways. Apparently, it is the most economical among all driveway options. It won't be hard to install as well. However, hiring highly skilled and experienced paving contractors can be quite a challenge. Make sure that the company has a good reputation and previous projects which are exceptionally done. Don't simply trust the contractor who offers the cheapest price. Remember that among them all, a percentage is scam artists.
It is best to hire contractors who are certainly up to the job so your paving project can be completed right on schedule. Some of these companies even offer free estimates. Keep in mind that while you're concerned with the job done on time, it is also vital that the workmanship is indeed good. It will ensure that you don't have to repeat the project and you won't worry about repaving your driveway for a long time.
The advantages of using asphalt apart from other pavers are quite evident. Its being cost-effective is perhaps its best benefit. Other pavers such as concrete are also a good choice, but it's mostly good for warm regions. And if you'd rather go for a stylish option, you can have bricks as pavers.
Choosing pavers is totally up to you, but you can definitely opt for asphalt if you want a quality and practical choice for your paving project.

Repair or Replace? What To Do About Your Aging Asphalt Parking Lot
Nothing lasts forever, and asphalt is no exception. There comes a time with every parking lot where you need to ask whether it’s time to repair it, or replace it altogether.
A properly paved asphalt lot can last 20 – 30 years, but the lifespan and condition of any lot depend on many factors. Let’s take a look at the various kinds of damage and repairs, and when you should replace a lot entirely.
The Types of Asphalt Damage
Cracking
Cracking can take many forms, including shrinkage, widening, edge cracks, slippage, alligator cracks, and reflection. Cracks are caused by many different factors, such as water penetration, oxidation from the sun, freezing, and thawing, and poor initial construction. Even the most minor cracks should be sealed as soon as possible, as small cracks can grow into bigger problems. Water or other debris can settle inside, causing the crack to grow, softening the base, and further threatening the integrity of the pavement. Larger cracks may be a warning sign of deeper issues.
Rutting
Rutting is when the pavement shows depressions, or grooves, from wear and tear caused by wheel loads. Ruts can be dangerous, leading to vehicles hydroplaning (from ponded water) that can result in loss of driver control. They can also be a result of deeper sub-soil or design problems, and lead to further deterioration. Ruts less than ⅓ inch deep can generally be left as is, but deeper ruts should be leveled and resurfaced.
When It’s Time To Repair
Crack Sealing
Crack sealing is exactly what it sounds like – filling small cracks to prevent further damage. Cracks that are straight or less than a quarter-inch wide can easily be repaired with a liquid filler. Before sealcoating or resurfacing, all cracks and existing damage must be repaired, so crack sealing is the first step towards further repair and necessary ongoing maintenance responsibility. A yearly schedule of crack sealing is best to prolong the life of your lot.
Seal Coating
After you’ve filled any cracks, you can apply a layer of sealcoating. Sealant keeps the lot looking new and prevents corrosion from a variety of elements, including water, oxidation, UV rays, and oil and gas spills. The ideal time to seal asphalt pavement is when deterioration is first discovered. A new asphalt lot should not be sealed until it is at least 6 months old, and should be resealed every 2 – 4 years, depending on weather and amount of traffic.
Resurfacing (aka overlaying)
Resurfacing, also known as overlaying, adds a new layer of asphalt, generally 1.5 – 2 inches in depth, on top of the older one. If done right, a new layer of asphalt can add 8 – 15 years to your current lot and costs less than a full replacement. All cracks and damage to the old layer need to be repaired before resurfacing, as un-repaired cracks will undermine the new layer. Resurfacing in cold weather can lead to premature deterioration, so the rule of thumb is to pave when temperatures are 50° F and above. Just because a lot is showing serious wear and tear and cracking, that doesn’t mean it needs to be replaced. Resurfacing is a great option to improve the condition of your lot without spending a lot of money.
Mill and Resurface
Resurfacing sometimes is not an option due to existing drainage patterns. When this is an issue milling and resurfacing may be a viable choice. Milling the surface involves the removal of the top layer of asphalt (usually 1” to 1.5”). Once the asphalt is removed, it is then replaced with a new layer of asphalt. Though this is one of the more expensive repairs, the quality of the final product and the service life can rival that of a new parking lot.
When It’s Time to Replace
Sometimes, a parking lot is beyond the point where even resurfacing will help. The answer to whether you should repair or replace essentially comes down to the condition of the lot’s base. Resurfacing is only as good as the surface it is layered on top of. If your parking lot is failing due to an underlying design, structural, sub-soil, or construction issue, none of the resurfacing options listed above will solve the problem in the long term. Though the parking lot will initially look better, the “repair” will be short-lived.
If a parking lot is approaching 20 years of age, or if 25-35% of the total surface area is in need of removal due to significant damage, it is generally more economical and effective to completely reconstruct the parking lot. With proper maintenance, your new lot can last another 20 – 30 years.
Proper evaluation and recommendations are critical to avoid any financial missteps in getting your parking lot back on-line.

Asphalt Maintenance Aspects For Commercial Property Managers
Asphalt maintenance is one facet of property management that is overlooked on a regular basis. If a property owner has a hole in their parking lot, it is not treated with the same urgency that a hole in their roof would require. Unfortunately, this neglect of their asphalt leads to more costly repairs in the future that could have been avoided if the property owner would have followed a preventative maintenance plan for their asphalt.
What is asphalt maintenance? Asphalt maintenance consists of protecting asphalt by employing the following methods (asphalt seal coating, crack repair and asphalt repair) to prevent damage to the existing asphalt.
So why should a property owner have their asphalt seal coated? From the very first moment that asphalt is installed, it starts a deterioration process. The asphalt is diminished when the binder that holds all of the aggregate (stone) together begins to oxide from sunlight, water, and other external conditions. Through the seal coating process, the asphaltic binder is now protected from the aforementioned external conditions. An additional benefit from asphalt seal coating is that the asphalt is now protected from the damaging effects from gasoline, oil, and de-icing salts. The most obvious benefit from asphalt seal coating is the restoration of the original color of the asphalt. The asphalt regains that new appearance for a fraction of the original cost.
Asphalt seal coating is a process in which coal tar emulsion or asphalt emulsion is sprayed or brushed on the asphalt surface. The seal coat material should be applied in two coats in general areas and three coats in the high traffic areas, such as drive lanes.
There is much debate as to what is the best application method for the seal coat material. There is a predominant mindset amongst "old school" seal coaters that brushing the seal coat material is the only way to go. However, there are some shortcomings in the brushing technique. By brushing the seal coat material the natural indentations of the asphalt are filled in and the asphalt loses its traction. Also, contrary to popular belief thicker is not better when applying the seal coat material. The sealcoat material should be applied at .17 gal/sq. yd. and should never exceed .51 gal/sq. yd. total.
With the shortcomings of brushing the seal coat material being stated, there is a better alternative. That alternative is spraying the seal coat material. This method allows the seal coat material to be applied evenly without filling the natural grooves of the asphalt. If a contractor states that they brush exclusively, take caution in dealing with these companies. Many times these companies have not invested in updated equipment, which will prevent them from completing the bigger seal coating jobs.
Another aspect of seal coating that is overlooked by customers is the mixture of the seal coat material itself. The material is should be mixed at 25 to 35 gallons of water per 100 gallons of concentrated sealer. Also, the seal coat material should be enhanced with 2-5 pounds of sand per every gallon of sealer. The sand is used to restore traction to the surface after the asphalt has been treated. When creating work specifications make sure to include the amount of desired sand required per gallon of sealer. The smoother the existing surface or the higher the traffic volume will require higher volumes of sand in the seal coat material.
In addition to asphalt seal coating, crack repair is vital to properly caring for asphalt. Due to the settling of the ground, poor base design and asphalt oxidation asphalt will crack. When the asphalt cracks it is exposed to water damage. Water penetrates the cracks and gravity pulls it into the sub-base (stones) which deteriorates that support structure. This deterioration leads to asphalt depressions, potholes, and further cracking. Also, in the winter when water expands in the cracks via the freezing process, the cracks widen over time.
Hot tar is applied to the cracks to prevent water penetration. Hot tar is melted to 375 degrees and poured into the cracks. To finish the crack repair process the hot tar is squeezed into the crack to create a 4-inch band. All debris should be removed from the cracks before treatment. Crack repair is a temporary fix and does not replace the need to actually replace the asphalt. However, crack repair is much more cost-effective than actual asphalt replacement.
It is said that if 30% or more of asphalt is deteriorated, it is more cost-effective to replace it. With that being said, the majority of property owners choose to replace certain sections at a time. One thing to keep in mind is that if an area of asphalt needs replaced because it was sinking, there is definitely a problem with the sub-base and that should be replaced as well.
If the asphalt needs to be replaced there are two methods for replacement. The conventional method is to saw cut the area and replace the asphalt and seal the seams with hot tar. Another modern method consists of using an Infrared Heater to heat the existing asphalt, then additional asphalt is added and the area is compacted. The benefits of using an Infrared heater is that the fix is a seamless fix that will no longer allow water penetration. The major fall back with using infrared is that if there is an existing sub-base problem, the asphalt will not be properly repaired if it is only re-heated and not actually removed to replace the underlying stone. In the right conditions, Infrared treatments to asphalt add extra benefits to the property owner because of the final aspect of seamless repair.
The bottom line is that property managers should incorporate an effective asphalt maintenance strategy into their overall preventative maintenance strategy. The benefits of asphalt seal coating, crack repair and asphalt replacement will pay dividends in the future through the avoidance of costly new asphalt. One last point, the asphalt maintenance and pavement marking industry have a wide fluctuation in the quality of contractors, so always do your due diligence in the selection process.
