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, Asphalt Sealing Cost in Pretoria 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.

Asphalt driveways can last as long as any hard surface if installed and maintained properly. However, usually the weakest point of the driveway is the edge. Edges are prone to several defects. The most common defect is cracking. Cracks generally form parallel with the edge of the driveway. This phenomenon happens usually when expansive soil is present under the driveway. The soil expands and contracts causing cracks that eventually transmit through the asphalt surface. Installing a decorative edge made from cobblestone or brick pavers will interrupt the point of expansion where the asphalt meets the yard. The edge will keep the asphalt from shifting; thus eliminating the cracking in the pavement.
Another source of problems is invasive vegetation. Zoysia grass and chickweed will easily migrate or expand through asphalt, especially fresh asphalt that is less than 3 years old. Grass can grow into an asphalt driveway by as much as 3 feet if not properly attended to. Controlling invasive grasses typically involves a regiment of spraying the edge with a herbicide to prevent growth of grass. Doing this works well, but isn't 100% effective. Zoysia and Chickweed spread by sending out runners under the soil. A home owner trying to protect their driveway might be satisfied with the progress they have made with herbicide treatments because they have kept an edge free of vegetation.
But eventually you may still see some sprouts pop up through the asphalt because a runner was able to escape the effects of the herbicide by traveling underground. Decorative edging installed on asphalt driveways by a qualified paving contractor will eliminate the potential of migrating grass invading the asphalt. When cobblestone or paver bricks are installed properly, it will create a solid barrier between the yard and edge of the driveway. Substrates used to hold the edge is non porous, therefore it leaves no voided areas for vegetation to grow. If invasive grass is left unattended on an exposed asphalt edge it will eventually ravel the edge. Cobblestone or brick paver edging will prevent damage from grass.
Decorative cobblestone and paver edges also keep vehicles from driving off the edge of the driveway. Driving off and on an edge of an asphalt driveway will eventually cause the edge to ravel, or break off. Not only is this an expensive repair, but it also leaves the home owner's yard not looking its best. Repetition will rut the yard and cause a bare spot, which eventually turn to mud. Decorative edges installed properly will reinforce the edge of the pavement, and also create a curb. The curbing effect will keep vehicles on the driveway and out of the yard.
Another important feature of decorative edging is its ability to control drainage. Not all, but some home owners desire a protective barrier against erosion or unwanted rain water. This is generally achieved by installing a machine curb or roll curb on the edge of the driveway. Machine curbs and roll curbs are formed from asphalt material. A decorative edge constructed of cobblestone or paver bricks can achieve the same results and look better doing it. A homeowner that has unwanted drainage or silt erosion from a neighboring property can be stopped by installing a decorative edge or curb.
Decorative edges add aesthetics and beauty to the home. A properly installed edge by a qualified paving contractor looks great and guards your investment by eliminating defects. Decorative edges can add up to 10 years to the life span of your new asphalt driveway. If you plan on replacing an asphalt driveway, you should consider implementing a decorative edge or curb into the design.
Asphalt Paving and Sealcoating - The Hard Facts of Asphalt Repair
There are several things you will want to keep in mind when making asphalt repairs. First, consider what has caused the asphalt to fail. The two most common reasons for asphalt failure are ultraviolet rays and water damage. Ultraviolet rays break down the asphaltic material in asphalt, resulting in cracks. The water penetrates the asphalt through the cracks and allows the sub base material to become saturated and washed out. When the base material is washed out from underneath the asphalt, it allows the asphalt to further fail and eventually turn into a pothole. Once a pothole is created, the base underneath the pothole now needs to be addressed before paying over it again.
To start, the base material that has been saturated must be removed. Normally the size of equipment necessary for excavation depends on the size of the troubled area. The material can be removed with anything from a small skid steer to large excavation equipment. Once the area has been evaluated and the material has been removed, the perimeter of the troubled area will need to be saw cut. Saw cuts are made first by popping chalk lines using a caulk box. These chalk lines are followed with the saw insuring straight cuts around the perimeter of the troubled area. By executing these steps in the beginning your end product will be stronger and more attractive.
After the saw cuts are made around the perimeter, neatly clean out asphalt and materials in the affected area. The area needs to be clean and free of debris. All wet materials should be removed from the area to insure a proper foundation for the new base material. After removing the wet materials, replace the area with a new compactable material, such as stone or crush and run. Depending on the size and depth of the excavation, it may be necessary to compact the new material in lifts as it is put into place. After placing the proper compaction of the base material, a tack coat should be applied. This tack coat will insure adhesion between the base material and the new paving.
Finally, you are ready for paving. The new asphalt paving material should be applied at the same depth as the existing asphalt. To ensure the area matches the elevation of the existing asphalt,you will need to make sure the new asphalt has been compacted with a vibratory roller compactor. Last but not least, clean up the entire work area with a blower and remove all excess debris.
