One of the most affordable and convenient methods for small-scale asphalt mending projects is to use a cold patch mix. Many property owners will tell you that this approach saves money, Driveway Repair Companies in Florida and can reduce the amount of labor required for the job, making it a great solution for small holes in parking lots, walkways, streets, and driveways. However, the process of cold asphalt patching can be accelerated with the right application techniques, saving property owners some time too! Customers, clients, guests, and occupants can use the pavement in the same day!
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.
Large-Scale Pavement Repair
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.

Although most people do not have the tools or equipment to actually install an asphalt driveway there are many things you can do to prepare the drive for paving work. The driveway without exception must have a solid base underneath to pave upon. Soft or wet spots are the most common reason for failure of the pavement itself. Cracking or alligatoring means the ground is unable to carry the weight of the vehicles driven over it. Severe wet spots will cause the pavement to fail totally and breakup into large chunks and cause the entire driveway to fail.
There are available today ground stabilization fabric materials that can be laid under stone sub base materials in wet areas to help solidify the sub base itself. The material is fairly expensive but may allow installation of a driveway where it would not be possible other wise. If placed directly on the earth below the sub base and over the wet area, once the sub base material is properly compacted the ground will support a great deal more weight without and shifting or movement. Many masonry supply stores carry these materials. It will take two people to roll out and handle the fabric as it generally comes in twelve foot wide rolls. A local excavating contractor may have some smaller rolls to sell. Give them a try as well.
Our first job is assure there are no wet spots either by installing some under drains, ditching along the edges to carry away surface water or actually replacing some of the wet earth with stone or other suitable materials. Sub base materials could be small and large stones, DOT item 4 materials, crushed gravel or bank run sand and gravel perhaps. The material needs to drain well and can be compacted with mechanical compactors. Drainage piping could be twelve inch corrugated piping which when installed will help water quickly pass under a drive or smaller four inch perforated piping run under the driveway areas encased in stone to provide constant pathways for water drainage without soaking the soils themselves. Water will always take the path of least resistance so any drainage piping installed will help the ground to dry much more quickly than nature would allow by itself.
Once you have solved any current or potential water problems you can move on to the actual asphalt sub base itself. Most homeowner driveways have a four inch base of gravel shale or item 4 installed when the home was built. Over the passing years, car tires break the shale down into very small pieces which will not provide a great sub base material. Adding new shale or stone can become a yearly maintenance project to maintain a smooth driving surface. As the stone or shale is pressed into the earth you are creating a thicker and thicker sub base. Depending upon whether you want your new drive to finish up higher or perhaps level than the adjoining lawns or gardens is how much sub base you want to have in the end. A typical residential driveway is ten feet wide with an actual driving surface area of about eight feet wide. For paving, you will need a solid ten foot surface to get a nine foot drive. Ten foot drive, eleven foot surface and so on. You need to have at least six inches of sub base beyond the actual finished paved width on both sides. The extra flat area is used to backup the asphalt and prevent the edges from crumbling. Remember also that asphalt and sub base may be as much as six inches thick and will require extra topsoil to backup the edge of the sub base and asphalt.
By adding sub base material and keeping the surface as level as possible, you will already have the sub base built for the paving man. In many areas of the US a material called blue stone screenings is available. This material is actually finely crushed granite and comes in three colors. Blue which will turn a darker blue when wet as time passes. Red that will also turn a lighter blue over time and yellow which stays yellow tinted forever. Once graded, this material becomes as hard as concrete on a driveway. I have seen blue stone screening surfaces snow plowed winter after winter without any plowing damage. A new dusting every few years maintains the crisp color and in-fills any depressions that may have developed. This makes a super sub-base for finished asphalt.
Well ahead of the time to have the driveway paved you should also install several conduits under the driveway for future landscape lighting. Depending upon the length of the drive, a crossing conduit every fifty feet or so should suffice. If an area is very rocky or wet, add additional conduits now before paving. Adding them later will require cutting and patching the asphalt and will not only destroy the driveways appearance but will provide a potential area for surface water infiltration. Conduit is cheap and if you never use it, it is better safe than sorry. Plastic (PVC) conduit is better than metal as it will last underground forever. Put caps on both ends to avoid any nasty surprises later on when you uncover them. Clearly mark the ends with stakes but also draw a little map and take measurements to each end from permanent objects in the yard. Once the grass grows back you will have no idea where the conduit ends are located. If you do this far ahead of the actual paving, your car traffic will compact the sub-base and will prevent any future sinking under the asphalt and thereby causing the asphalt to crack. You do not want to have to cross the new asphalt with anything later on..
Call several paving contractors for prices. The nicest guy may not do the nicest job. Make sure you tell each one exactly the same things you want. If you change the description of the work, you will not get comparable prices. Write down what you want done and then give them a copy. Ask for a written quote to make sure they included everything on your lists. Will they pickup all spillage? Are they insured against yard damages to flowers or trees or your house? How long is driveway guaranteed? How thick with the rolled asphalt be when done? Loose rolled asphalt 3 inches thick will be only 1 1/2 to 2 inches thick when rolled. Ask questions before they do the work. Get a written signed contract and a copy of their insurance policy. Be very careful with down payments. If they insist on one, make sure it is not a major portion of the contract value. Many times a down payment is paid and the contractor never shows again. Do not be suckered in by sob stories. Reputable contractors have open accounts at asphalt plants and do not need your money to buy the asphalt. If you sense something is awry move on to someone else. Ask neighbors about his work or stop at someone's house who he has just paved their driveway. Most people are proud of their new yard and will glad to talk to you. Call the Better Business Bureau and check on the contractor as well. It may sound like you are a bit over cautious but after all it is your hard earned money.
Once you have selected a contractor ask him/her if there is anything else you can do to save a few bucks on the price. Maybe removing a pre-installed asphalt driveway apron or removing adjacent features such as signs or statues or whatever else that he figured on doing for you. If you save fifty bucks on the price, that is fifty dollars towards your next project.

What Is Asphalt Paving
You're looking at your asphalt driveway and it appears to be in rough shape. What should you do? Will some repair work do the trick? Should the driveway be resurfaced, or does the whole thing need to be ripped up and redone from scratch?
Perhaps the best thing to do is to consult a few asphalt paving contractors and get their opinions, and (often free) estimates. This article can give you a general idea of what's going on, what to look for in an asphalt paving contractor, and what to include in your contract.
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.
Various factors may cause premature wear
Although a properly installed asphalt driveway can last 15 to 20, even 25 years if properly maintained, extreme weather conditions, extra-heavy loads and shortcuts taken during construction can all cause premature wear and failure.
Beware of "traveling contractor" scams
Beware of any asphalt paving contractor who rings your doorbell and claims to have some "leftover materials" from another job, and if you agree to the work "right now," you'll get an amazing discount. If this happens to you, call the police. It is a scam. Reputable contractors calculate the materials they need very carefully, and any small amount left over from a job would never be enough to complete an entire new job. If these con artists do any work at all before taking off with your money, it will most definitely be shoddy.
Tips for hiring an asphalt paving contractor
It is best to deal with registered, bonded, adequately insured and licensed (where companies. Many reputable paving contractors also belong to trade associations, such as the National Asphalt Pavement Association (NAPA), the National Pavement Contractors Association (NPCA), or various state-specific associations.
When hiring a contractor to resurface or install a new asphalt driveway, always get a list of references and check them. Ask references about the quality of the contractor's work, their attention to details, and if the work was competed on time. You can even go and inspect previous work.
What to include in the contract
Once you decide on an Asphalt Paving Contractor, consider these points when drawing up a contract:
Clarify who is responsible for re-hanging gates or other doors, if needed, due to raised pavement levels.
Who will raise any water valves or sewer inlets to meet the asphalt around them - you, a plumber, or someone else? Who pays?
Specify that the surface must be graded to provide proper drainage.
For new installations, specify that the sub grade will be compacted before the base layer is applied.
Specify how many layers are included in the job, a description of the materials that will be used for each layer (sub-base, base and asphalt), and the thickness of each layer when compacted. Two separate layers, or lifts, of asphalt is preferred, totaling at least 3 and preferably 4 inches. Sub-base and base should be at least 6 inches each, comprised of limestone rocks with 3-to-4-inch diameter and 2-to-3-inch diameter, respectively.
Include the payment schedule and a guarantee of the finished product.
Determine whether a building permit is required, and specify that it is the contractor's responsibility to obtain one on your behalf, if needed.
