Sealcoating is a crucial process in the preventative maintenance of any parking surface. However, because sealcoating is water based and cures by releasing all the water from their applied films, cure conditions are in credibly important. Sealcoatings cured under improper conditions are likely to fail prematurely.
Proper Cure Conditions
- Temperature: Sealcoating should only be applied if both ambient temperature and pavement temperature are above 50°F and below 85°F. When sealcoating below 50°F, the asphalt particles do not soften to form a continuous film. Because of this, the sealcoating will not only appear grey, but will also lack integrity. When sealcoating above 85°F, the sealcoating will lose its fluidity too rapidly, immobilizing binder particles and preventing them from fusing and forming a continuous film.
- Humidity: Humidity directly influences the rate of water loss from the sealcoating film. Sealcoating applied when it is overly humid will take a long time to cure. Sealcoatings will cure much faster at lower humidities.
- Wind: Wind can play a very big role in cure times. Under humid conditions, a nice breeze can help sealcoating cure faster. However, under low humidity, wind may cause sealer to cure too fast.
These conditions are the recommendations of the industry and its research association, Pavement Coatings Technology Council (PCTC).

Sealcoating is a crucial process in the preventative maintenance of any parking surface. There are many benefits to sealcoating, including:
Aesthetics: A fresh new sealcoat gives your asphalt a dark black color, greatly improving its appearance. Sealcoating will also make your asphalt look cleaner, as rain can more easily wash dirt and debris away.
Preservation: Sealcoating will preserve the resilience of your asphalt parking surface and will keep small cracks from becoming big structural problems.
Visibility: Sealcoating will make your traffic lines more visible.
UV Rays: The sun can greatly damage your asphalt surface. Sealcoating protects your parking lot from harsh UV rays.
Chemicals: Sealcoating will protect your parking lot from the effects of chemical spills, like gasoline or oil.
Waterproofing: Sealcoating locks moisture out. And, as we all know, moisture and asphalt do not mix…especially with winter right around the corner.
Save Money: Sealcoating costs pennies per square foot. Asphalt repairs cost dollars per square foot. You do the math.
So do the right thing for your parking lot and have it sealcoated every 2-7 years, or as needed. This will protect your asphalt surface and greatly minimize the need for constant maintenance and repairs.
If damage still occurs to your asphalt parking lot and it is in desperate need of a little TLC, contact an experienced asphalt company today – a company like PTG Enterprises.

Is your driveway in rough shape? Will repairs do the trick? Does it need to be resurfaced? Should you have it redone professionally? These are all questions that homeowners ask themselves when faced with a dilapidated driveway. Ultimately the best thing to do is the contact a professional like My Pavement Guy, but there are some things you can consider on your own.
According to this article on EzineArticles there are some important things to think about before consulting your contractor:
Maintenance is good medicine, but it’s not foolproof
Asphalt driveways don’t remain smooth and black forever. You can take steps to maintain your driveway by sealing and protecting it, but often the effects of heat, ultra-violet rays, and substances such as salt, oil, gas and grease take their toll. And if those don’t get you, then cracking and water penetration eventually will.
Your driveway may be corroded, worn out, or have cracks, which could all warrant a resurfacing job if the condition is severe enough. As a general guide, if repairs are needed on more than 25 percent of the surface, it is more cost-effective to do a hot mix asphalt resurfacing job over the entire driveway.
Say no to cracks!
Asphalt pavement is hard and brittle, and as a result, cracks will develop over time. Ranging from hairline to an inch wide or more, cracks are your driveway’s worst enemy because they let water in. In colder climates, freeze-thaw cycles can be very destructive, and can wreak havoc on your driveway if water penetrates the cracks, then expands as it turns to ice. And even in warmer climates, water penetration can cause serious damage. The larger the crack, the more serious the problem, and the sooner it needs to be fixed. Cracks that are left un-repaired will lead to serious deterioration of the pavement and even to the base layers, requiring complete replacement of the driveway – sooner rather than later in colder climates.
Can it be fixed or do you need a new driveway?
Whether you’ll need to rip out your existing driveway and install a new one, or if you can get away with resurfacing – or even some patchwork and crack-filling – depends largely on the condition of the base layers, or foundation. However, if cracking covers 3/4 of the driveway, the surface is too far gone to repair. The root of the problems may come from lower down, and a complete overhaul should be considered.
If your driveway has been resurfaced several times with hot mix asphalt and keeps deteriorating prematurely, it is likely a problem with the foundation, and you should consider installing a whole new driveway. Likewise, if there are areas that have depressions or mounds, they should be completely reconstructed from the base. If you have several of these areas, a new driveway might make sense.

Even the best pavement will crack and deteriorate after time. But there are ways in which you can extend the life of your pavement. One of these ways, as this article from PaveManPro.com explains, is Pavement Sealer.
Asphalt hardening is an oxidation process and is a function of its exposure to air on the surface and within the pavement. If circulation of air through the interconnected void spaces in the pavement can be prevented or reduced, the rate of hardening of the asphalt will be slowed and the life of the pavement extended. Pavement sealers are used to do just that – close the surface pores to lengthen the life of the pavement.
Pavement sealers come in two basic formulas: Refined Tar-Based Sealer and Asphalt Based Emulsions.
Refined Tar-Based Sealer
Refined tar is a by-product of the distillation of crude coal tar. Refined tar differs from crude coal tar in that during the distillation process, the lighter end oils are removed from the refined tar. Refined tar based sealer is resistant to attack from petroleum based products. This property makes it ideally suited for parking lots or other locations where concentrations of oil and grease leaks are common. Refined tar-based sealer is also highly resistant to ultraviolet light bleaching. It is stable, homogeneous, easy to apply, and has been handled safely by professionals and do-it-yourselfers for decades. Refined tar based sealer has traditionally been used at gas stations, truck and bus terminals, airport aprons and taxiways as well as on residential driveways and commercial parking lots.
Asphalt based emulsions
Asphalt-based emulsions have many of the same beneficial properties as refined tar- based emulsions, but they are less resistant to corrosion by petroleum-based products, ultraviolet bleaching, and salts. An asphalt emulsion is a mixture of liquid asphalt and water. Manufacturers add special chemicals and pigments to the asphalt emulsions to improve performance but they remain susceptible to the damage caused by petroleum products.
Pavement sealers allow homeowners and businesses to maintain their asphalt effectively and economically. Research has shown that when asphalt pavement is maintained properly, the owner can extend the life of their pavement and delay costly reconstruction.

It’s a hole in the road. How hard can it be to fill a hole, right? Well, you might be surprised. Pothole repair is tough work and requires a trained crew and some specialty equipment. This article from PaveManPro.com explains the lengthy repair process.
How to repair a pothole:
1. With a pavement saw or pneumatic hammer, cut the outline of the patch, extending at least 0.3 m (I ft.) outside of the distressed area. The outline should be square or rectangular with two of the sides at right angles to the direction of traffic.
2. Excavate as much pavement as necessary to reach firm support. If a patch is to be an integral part of the pavement, its foundation must be as strong or stronger than that of the original roadway. This may mean that some of the sub-grade will also have to be removed. The faces of the excavation should be straight and vertical.
3. Trim and compact the sub-grade.
4. Apply a tack coat to the vertical faces of the excavation.
5. Backfill with the asphalt mixture. Using a shovel or skid steer loader place the mixture directly from the truck into the prepared excavation. The maximum lift thickness largely depends upon the type of asphalt mixture and the available compaction equipment. Asphalt concrete can and should be placed in deep lifts, since the greater heat retention of the thicker layers facilitates compaction. From a compaction standpoint, patches using asphalt concrete can be backfilled in one lift. However, when placing a patch that is deeper than 3 cm (5 in.) it is often useful to leave the first lift 2.5 to 5 cm (I to 2 in.) below the finished grade, making it easier to judge the total quantity of mixture required for the patch.
On the other hand, patches constructed with mixtures containing emulsified or cutback asphalt must be placed in layers thin enough to permit evaporation of the diluents that make the mixture workable.
6. Spread carefully to avoid segregation of the mixture. Avoid pulling the material from the center of the patch to the edges. If more material is needed at the edge, it should be deposited there, and the excess raked away. The amount of mixture used should be sufficient to ensure that the after compaction the patch surface will not be below that of the adjacent pavement. On the other hand, if too much material is used a hump will raise.
7. Compact each lift of the patch thoroughly. Use equipment that is suited for the size of the job. A vibratory plate compactor is excellent for small jobs, while a vibratory roller is likely to be more effective for larger areas. When compacting the final lift (which may be the only lift), overlap the first pass and return of the vibratory roller or plate compactor to no more than 5 cm (6 in.) on to the patch on one side. Then move to the opposite side and repeat the process. Once this is accomplished, proceed at right angles to the compacted edges, with each pass and return overlapping a few inches on to the uncompacted mix. If there is a grade, compaction should proceed from the low side to the high side to minimize possible shoving of the mix.
8. When adequate compaction equipment is used, the surface of the patch should be at the same elevation as the surrounding pavement. However, if hand tamping or other light compaction methods are used, the surface of the completed patch should be slightly higher than the adjacent pavement, since the patch is likely to be further compressed by traffic.
9. Check the vertical alignment and smoothness of the patch with a straightedge or string line.
So next time you complain about that pothole down the street not getting fixed or next time you think to yourself, “hey, I could do that in half the time,” remember that pothole repair is not a quick fix. Properly patching a pothole takes time, know-how, and a lot of energy.

Unfortunately, even the best pavement is not indestructible. Heavy traffic usage and weather changes, along with several other outside factors, can lead to pavement distress, which is noticeable physical damage on roads or sidewalks. If not dealt with quickly, pavement distress can lead to more serious problems, all of which can significantly shorten the lifespan of your pavement.
But how can you spot pavement distress in time? This article from eHow.com explains how you can quickly identify pavement distress.
1. Assess cracks on the surface of the pavement. Alligator cracking appears as a network of cracks, forming a pattern somewhat like the skin of an alligator or wonky squares. As the U.S. Department of Transportation outlines in its “Pavement Distress Identification Manual for the NPS Road Inventory Program, 2006 -2009,” the severity of the distress can be measured. It is considered low when the width of the crack is less than 1/4 inch in width. However, the alligator distress is serious when the cracks are more than 3/4 inch wide.
2. Check the pavement’s surface for long strips of cracking. These are ruts that run either along the length of the pavement or sideways across the surface. In places where the cracks are more than 3/4 inch in width, the distress is considered serious and can buckle the pavement, causing bumps. Hot weather can cause this type of pavement distress.
3. Identify gouged-out areas or dips on the surface of the road. Pavement distress is characterised by potholes. These are concave holes on the surface, which are a nuisance for drivers. The holes can cause punctures in tires, gather water and lead to further cracking.
4. Look for dark square or rectangular patches of asphalt on the pavement. Distress can be identified by finding discolored areas where potholes or previous distress marks have been filled or covered over. The replacement asphalt causes a dark patch to be seen. Cracking, ruts or potholes can often be seen in proximity to the patching, which is indicative of pavement distress.
5. Crouch down and look across the surface of the pavement. Identify two lines of depressions in the road’s surface. If these are in the direction of the wheel paths, this distress is called rutting. Rutting occurs when continuous use of the pavement by heavy vehicles causes the surface to sink. It is classified as severe when the depressions are greater than 1 inch below the surface of the pavement.
Once you have identified pavement distress, it is time to repair the damage. There are several products available that allow you to do the job yourself, but if you want to ensure your pavement is properly fixed, it is probably best to call a professional.

After Concrete is laid, the inevitable settling, shifting and moving will occur. But in extreme cases, when the ground settles below the concrete or when a tree root comes into contact with the pavement, walkways or patios can break and lift. These unsightly blemishes on your otherwise pristine concrete surface can ruin the entire look and feel of your patio or walkway. And with Memorial Day right around the corner, you are going to want your home to look perfect for your guests.
This article from eHow.com provides 4 ways in which you can quickly repair that broken and lifted concrete.
Instructions
1. The easiest way to repair lifting concrete pavement is to grind it down. Most driveways are at least 6″ thick by code, so there should be sufficient grinding depth. Walkways and patios are 3″ – 4″ in thickness. Renting a scarifier is probably the most practical way to do this yourself. This is not an easy machine to use, so if you are not comfortable with the job, don’t hesitate to call in a professional.
2. If the lifting is the result of tree root growth, you will have to grind your cement down repetitively as the roots will continue to push the concrete up. A better solution is to remove the concrete pavement all together, cut out the offending root(s) and re-pour the cement.
3. A quick fix would be to fill in the ‘step’ created by the raised concrete with a cement adhesive and concrete/polymer fill. Even if you carefully rough up the lower cement, this ramp-like fix will only be a temporary patch at best. It will chip away fairly quickly, especially on a driveway pavement with heavy traffic.
4. Better left to the professionals, you can float a slab of concrete that has sunk into the ground by drilling holes and pumping in a cement mix. This will literally float the slab back up with the pressure of the concrete beneath.
Now you can enjoy your Memorial Day barbeque without having to hear, “What happened to your patio!?” at least 50 times. If you have any questions or if you would rather leave the repair work to the professionals, contact PTG Enterprises by calling 410-636-8777 or click here today!

From the moment your asphalt is installed, it begins to deteriorate. This means that to ensure you have a top-notch parking lot for years to come, you will need to take certain steps to maintain that asphalt. This preventative maintenance will not only make your parking lot last longer, but, in the long run, it will save you money.
Here are a few simple steps you should take to keep your lot looking pristine.
Crackfill
Properly filling cracks is a job of tremendous importance. By filling a small crack properly, you will prevent that fissure from growing and becoming too big to handle by yourself. Filling small cracks saves you from paying to have large cracks repaired.
Sealcoating
This is another great way to improve the overall look of you lot while going the extra mile to protect your parking surface.
Re-Striping
Once the original lines are painted on the asphalt, constant re-striping is required ever 12-18 months.
Signage
Not only will your lot begin to deteriorate, but often signs are knocked down, dented, vandalized or even stolen. It is important to properly maintain your signs – not only for that instant curb appeal, but also for safety.
Wheel Stops
Wheel stops play an integral role in maintaining clear sidewalks and protecting signs. If your wheel stops are damaged, it could negatively affect everything around them.
Now you are well on your way to a beautiful, long lasting parking surface.
