Winter is just around the corner, and it’s important to start preparing your parking lot and pavement to prevent freeze/thaw damage. If the asphalt has any cracks or potholes, now is the time to crack fill the pavement before the temperature gets too cold. Learn more about freeze/thaw cycles and why it’s crucial to crack fill your parking lot before winter arrives. (more…)

Why You Need to Crack Fill before Winter Hits Maryland

Friday, October 9th, 2015

Crack FillWe may not have it as bad as some other states, but Maryland can have its fair share of very harsh winters.

If there is any damage to your pavement, you will want to crack fill before the snow and ice arrive. We can’t over-stress the importance of crack fill before the harsh realities of a Maryland winter set in. (more…)

Crack Fill This Fall Will Prevent Freeze-Thaw Damage This Winter

Thursday, October 16th, 2014

Crack FillFall has just arrived, and winter is not far behind! Is your parking lot safe? Taking care of your parking lots and driveways might not be the first thing you think of when preparing for winter and the snow. Although it seems like you have months before you have to worry about such things, now is the time to take action. If there are any small cracks in the asphalt, you should look into repairing them as soon as possible. Why? Because rainwater as well as melted snow can seep into those cracks and create even larger problems that you don’t want or need!

Freeze-thaw damage to your parking lot occurs when water seeps into the crack in the asphalt and freezes below the roadway and causes the pavement to rise. When this ice thaws, the pavement lowers again, but causes a dip in the road, which then breaks and becomes a pothole. That means an even bigger, more expensive issue to deal with.

The nights are getting cooler and cooler as we go deeper into these fall months, so it’s important to crack fill your parking lots before freeze-thaw damage occurs! Crack filling is just that – filling in the cracks in the pavement. It can have a huge impact on the condition of your parking lot during and after the winter months. You should crack fill now so that you don’t have to repair a pothole later.

Although this is an important issue to take care of as soon as possible, you shouldn’t try to crack fill your parking lot by yourself.

Asphalt Patching, Crack Fill and other forms of Asphalt Maintenance

Thursday, August 1st, 2013

Asphalt Maintenance

Asphalt is not indestructible. It will not last forever. In fact, even with regular maintenance, your asphalt parking lot will only last 15-20 years. The key phrase in that last sentence is “with regular maintenance.” Without maintenance, your asphalt will deteriorate much quicker.

Asphalt maintenance refers to the methods and techniques used to prolong the useful life of asphalt pavement.

Forms of Asphalt Maintenance

  1. Crack Fill: Over time, cracks will undoubtedly form in your asphalt. This is normal and easy to deal with. Crack filling is the process in which asphalt cracks are sealed to prevent further water penetration and thus further damage. When water finds its way into the cracks and crevices in the surface of your asphalt, it works its way to the base, slowly eroding your parking lot from beneath. The end results are cracks, pot holes, and, eventually, premature pavement failure.
  2. Asphalt Patching: Unlike an overlay, which is the placement of new asphalt on top of the old, damaged asphalt, asphalt patching involves the removal of the damaged asphalt, typically in a single area. Once this is done, new asphalt is poured onto the existing sub-base or sub-grade.
  3. Overlay: An overlay is when a new and additional layer of asphalt is installed over what is already there.
  4. Sealcoating: This preventative maintenance measure helps safeguard asphalt from the harsh effects of gas, oil, salt, weather conditions and oxidation. Sealcoating, which is essentially a thin liquid layer added over a paved surface, is designed to block water infiltration, protecting your asphalt surface and extending its useful life.

Asphalt maintenance will help extend the useful life of your asphalt, saving you both heartache and money. So what are you waiting for? Pick up the phone and call PTG Enterprises today! We have been in the asphalt paving business for more than a decade and know a thing or two about asphalt maintenance. So do yourself a favor the next time you have an asphalt project.

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.

Pothole Repair: It’s a Bigger Job Than You May Think

Friday, June 24th, 2011

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 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.

How to Identify Pavement Distress

Thursday, June 2nd, 2011

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 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.

Repairing Lifted Concrete

Wednesday, May 25th, 2011

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 provides 4 ways in which you can quickly repair that broken and lifted concrete.


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!

Pavement Maintenance

Wednesday, March 23rd, 2011

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.


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.


This is another great way to improve the overall look of you lot while going the extra mile to protect your parking surface.


Once the original lines are painted on the asphalt, constant re-striping is required ever 12-18 months.


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.
