Asphalt is a sticky, black and highly glutinous liquid, or semi-solid form of petroleum. Its primary use is for the construction of driveways and road and occasionally used to seal flat roofs, where it is used as the glue or binder mixed with combined particles to produce asphalt concrete. The most common occurrence of cracked asphalt happens when water seeps into the pavement through open cracks, and potholes occur. When the water freezes, expansion occurs thus widening the crack further. During warm weather, the iced water melts away leaving the cracks with open voids. A pothole emerges when the surrounding walls fall into the void. (more…)

Why Does Asphalt Crack?
Friday, June 9th, 2017What is Infrared Asphalt Repair?
Friday, June 2nd, 2017Infrared asphalt repair is a tried and true method to seamlessly repair cracks in
asphalt pavement. It combines hot-mix asphalt with the existing, damaged asphalt
and then compacts the area for a smooth, seamless finish.
If you look at your asphalt surface and notice potholes, divots, cracks, heaving, or
any other kind of uneven areas you may want to consider infrared repair. (more…)
Pothole Repair: It’s a Bigger Job Than You May Think
Friday, June 24th, 2011It’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.

How to Rid Yourself of Pavement Ants in Your Driveway
Wednesday, May 18th, 2011Pavement ants, also known as house ants or sugar ants, can be quite a nuisance. They set up camp in your yard or inside the cracks in your pavement and eventually work their way into your home. The best thing to do when you find pavement ants is to rid yourself of the infestation as soon as possible.
But how can you do that? You are no exterminator and you don’t want to have to run to the hardware store to buy ant spray, right? Well, you can use one household item to help assist you in your quest for an ant free existence – salt.
That’s right, all you need is everyday salt. This article from eHow.com explains several solutions to rid yourself of those pesky pavement ants using nothing but common table salt.
1. Sprinkle ordinary table salt on cracks in the driveway, along the sides and where the ants are present. Make sure the driveway and surrounding areas are dry before applying salt for the best effectiveness.
2. Repeat weekly until the ants are gone. After consuming the salt, the ants will drink water or other moisture until they essentially explode. Be aware that the salt will also kill any weeds or plants present, so use caution.
3. Draw a line with salt at the end of the driveway on the pavement to prevent the ants from crossing over into the lawn or home.
4. If table salt is not effective, purchase a sweet ant bait trap that contains boric acid salt. (Boric acid is a hydroponic salt.) The ants are attracted to the sugar in the bait, consume the boric acid salt with the sugar, and then take the poison back to their home, where it spreads to the other ants.
5. Place the ant baits along the sides and ends of the driveway. Use caution when using ant baits because boric acid can be toxic to pets and humans as well as insects.

How To Maintain An Asphalt Driveway
Wednesday, May 11th, 2011There are several factors working against your asphalt driveway – heat, sun, oils and everyday wear and tear – that will, over time, slowly deteriorate your parking surface. So if you don’t want your driveway to crumble around you, you need to constantly maintain your asphalt.
This article from eHow.com outlines 6 easy steps to keep your asphalt driveway looking like new.
1. First, take good care of your driveway throughout the years. Keep grass clippings off of it by sweeping after every time you mow your lawn. The seeds in the clippings can find their way into tiny cracks in your asphalt and sprout grass. Not only is it an eyesore, it can make the cracks even larger. As soon as you see any weeds growing in a crack or hole in your driveway, spray it with weed killer so the crack doesn’t get larger. Also remember to clean up any substance from your asphalt driveway as soon as possible. If you have oil leaks or something of the like that is puddling in your driveway, take the time to clean it up with a little soap and water. These are all good steps in caring for your asphalt driveway.
2. Once every 2-3 years you will want to reseal your driveway. This is what’s going to make the biggest difference in the appearance of your driveway. Resealing is actually just putting a very thin new layer of asphalt on top of the existing driveway. Visit your home and garden retailer of choice to find the products listed in the “items needed” section such as the crack filler, squeegee, and sealant.
3. Plan to reseal on a warm day when it’s about 50 degrees or a bit warmer. Also plan to NOT use your driveway for 24-48 hours after application. Once you’ve moved all the cars off of the driveway, trim any grass at the edges of your driveway back. Now you’ll have to clean your driveway’s cracks and holes. You can use household cleaners, or, if you have a power washer, it’s much easier to use the power washer along with a driveway cleaner/degreaser you can find at places such as Lowe’s or Home Depot. Let the entire driveway dry thoroughly before moving on.
4. Now, fill any cracks or holes you may currently have in your driveway with an asphalt crack filler. Follow the directions on the particular bottle you choose, some work differently than others. Allow the patch to dry for 24 hours (or whatever your product recommends).
5. The next day, sweep the driveway. Now sweep again with someone else helping by washing the driveway alongside you with a hose. It’s very important for the driveway to be clean of all dirt and particles – even in the small cracks. Now use the power washer and driveway cleaner (or your choice of household cleaner) again, but this time all over the driveway. You may need to scrub severe oil stains with a brush. Let it dry.
6. Apply the driveway sealer (usually comes in a 5 gallon bucket) in thin coats. Use the squeegee to apply in a thin layer. It’s better to do two very thin layers than one thick layer. Keep stirring the sealer in the bucket throughout the process. Remember to check your particular product for specific requirements (some need water misted on it, etc). Now block your driveway off and don’t touch it for 24-48 hours.
If this does not help, it may be time to consult a professional. If you have any questions, contact PTG Enterprises by calling410-636-8777 or click here today!
Potholes and Repair
Wednesday, March 30th, 2011How do potholes happen?
Potholes are severe manifestations of pavement fatigue cracking resulting in a total loss of asphalt integrity in a localized area. This creates a hole in the road. It is not uncommon to have a pothole extend through or into the aggregate stone base. Potholes occur when water seeps into cracks in the asphalt surface of a road or driveway. This water will freeze and expand in the cold weather. A pothole forms when dirt and gravel are forced out leaving a hole. The ice will eventually melt away, leaving a pothole.
How can you quickly fix a pothole in your driveway?
For a very wide crack or pothole, shovel in packaged cold-patch blacktop, leveling large areas with an iron rake. Compact the material with a rented tamper or the end of a 4-by-4. Add more material until the hole is slightly overfilled. Cover it with scrap plywood and drive over it.
If you are looking to fix a pothole on a commercial parking surface or if you want a top quality repair, it is probably best to call a professional.
What does My Pavement Guy have to say on the subject?
In the winter, potholes should be temporarily filled with a cold-patch mix material to protect against vehicle damage and/or lawsuits. Please note that this is only a temporary fix and left untreated correctly the pothole will most likely reappear. In the spring and summer months, potholes should be permanently patched.
Full-Depth Patching is the most common type of patching. This is where the pavement is completely removed in the troubled area and replaced. These areas are usually suffering from severe distress and / or sub-base failure. This is a permanent fix.
