Continue reading to learn some great tips on how you can shorten the amount of time it takes for the cold patch asphalt mix to harden, and drastically cut down on turnaround time, from project start to finish.
Ease of Use
The primary reason why this product is the go-to choice for small hole repairs in asphalt pavements is the ease of installation. There is no long, extended process of preparing or mixing materials. Instead, the air does most of the work. You simply pour the mix directly into the hole, compact it with simple manual tools (metal tamper or piece of lumber), and leave it to air dry. The mix turns into a permanent surface patch after extended contact with air.
The drying process, also known as curing, is very important to establishing a solid, stable surface that lasts a long time. If you want a permanent repair for your asphalt, you need to make sure the entire process is done correctly. If you want to speed up the curing stage of your pavement repair project, you can try a few recommended tips.
You can use gravel to create a more dense space within the hole, which may help to establish lasting strength. Just fill the hole with gravel, little by little, while using your compacting tools to compress the gravel with each layer. Do not fill the hole all the way to the top; be sure to leave 2 inches of space below the surface line for your cold patch mix.
Pouring Your Mix
As you pour your mix, exceed the surface line by half an inch. This means that your mix should go over the top of the hole by a ½ inch. Then use your compacting tools to compress your material down until it is properly flattened. You may need to repeat this step two or three times to get a proper fill.
Asphalt cold patch mix cures by having contact with air. You can speed up the drying process by using hair dryers or commercial paint dryers. If you are going to use a hair dryer, you will need to manually operate it in a steady, sweeping motion to ensure even curing. The material is near dry when you cannot easily press into the surface with your hand.

For large-scale pavement repair jobs, you need a professional paving company. They have the training, equipment, and resources to provide dependable work in a convenient time frame. Be sure to choose a company that is licensed, bonded, and insured, and retains decades of experience in the road construction industry.

Homeowners often try to decide if they should replace their driveway with asphalt or concrete. It is not always an easy decision; especially when you consider the cost that is involved in such a large renovation project. This article specifically addresses the pros and cons of installing an asphalt driveway versus a concrete driveway.
- Appearance; concrete just looks better. It is the standard for even the most expensive homes.
- No annual maintenance; Once initially sealed, concrete doesn't require any annual maintenance
- Lasts much longer; Concrete should last 20 years or more if installed correctly.
- Concrete can be stained/stamped to look like brick, slate, or stone for a rich look
- Concrete is versatile in how it is placed and designed. Curves, color, finish, and textures add versatility to the appearance of concrete.
- Concrete adds value to your home. People just associate concrete with being the best money can buy.
- It's concrete! I'm a mason and I'm biased!
- Concrete is more expensive: The initial cost of installing a concrete driveway is slightly more than the cost of installing an asphalt driveway. Initially that is.
- Prone to cracking: This is a big one. Concrete cracks. It's what concrete does. It is rigid and when pressure from the ground below exerts its powerful forces against the concrete, the concrete cracks. However, how bad it cracks and where is often up to the mason that installed it. With proper base preparation and proper expansion cutting, cracks should be hidden and kept to a minimum.
- Concrete is susceptible to road de-icer which could ruin surface finishes. It is true that in the northern climates where roads are treated with salt or other road de-icer, the finish on your concrete can be damaged by road de-icer IF it is not properly sealed with a premium penetrating sealer.
- Cheaper initial cost. If you need paving material on your driveway and you don't have the money for concrete, asphalt can be an excellent alternative. It is certainly better than dirt, mud or stone.
- Asphalt must be re-sealed once a year. You either have to pay someone or you have to do it yourself; either way, this is the worst part of owning an asphalt driveway. If you skip sealing your driveway, it will degrade much more quickly and cost you even more.
- Asphalt wears out faster. No matter if you seal it or not, asphalt just crumbles, cracks, and sinks with vehicle weight. It is not as durable as concrete.
- Asphalt soaks up oil and gas. Asphalt is susceptible to oil and gas spills/leaks from your car. Every place you park your car, there will be stains.
- Asphalt is Dirty; with a capital "D". Asphalt is just plain dirty. Walk around on your asphalt driveway and then look at the bottom of your shoes. Yuck. The binder used to keep asphalt together is made with tar. When you seal the cracks in asphalt, you use tar. Tar sticks to everything; including you. Then you track that into your house.
- Asphalt costs more: Wait. Didn't I say it was cheaper? Yes, but only initially. In the long run, asphalt is going to cost you more because of having to replace it when it wears out. Not to mention it cost money to seal it every year. It is just not made to last as long as concrete. This con just crossed out the only "pro" for asphalt.
There are many factors to consider as you think about which type of driveway to install. It is easy to see, concrete is initially more expensive, but will outperform and therefore outlast asphalt every time; making concrete the cost effective solution. Maintenance free concrete will not only add immediate beauty and value to your home, it will be a permanent driveway solution that adds beauty and value to your home for decades to come.
Benefits, Limitations and Uses of Roller Compacted Concrete - RCC
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.
