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 Companies Near Me in Sunninghill 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.

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.
What Is Asphalt Paving
Many people think the since you drive your car on both your asphalt driveway the concrete slab in your garage that they should both be sealed with the same product. This is absolutely false. Concrete and asphalt are diametrically opposed materials and should be treated completely differently. What works for one will not work for the other.
A sealer on asphalt actually performs two functions. First, it makes the surface look great as it tends to add back the black color and also makes it cleaner looking. Second, it protects the aggregate from loosening do to degradation of the asphalt base. Both of these benefits are important.
Wear ability studies have indicated that the best asphalt sealer should be made from coal tar instead of liquid petroleum asphalt. This seems counterintuitive but it is true. Coal tar is a byproduct of the manufacture of coke for steel manufacturing. Coke is produced from raw coal and during its formation a liquid byproduct is formed. This liquid is very sticky and cures to a very good protective surface when spread out on a roadway or driveway of asphalt.
One thing to consider with these types of sealers is that they should not be used in doors. Coal tar has volatile organic compounds which gas off during the curing process. These have been proven to be a health risk. Also, the coal tar does not bond well with concrete so another product needs to be used for your garage slab.
The best sealer for concrete is an epoxy floor coating. Epoxies cure to a very hard and tough surface which will protect your floor surface from damage and wear. They can also be tinted so your floor can match the color of your home or you can use a complementary color to your pride and joy car.
The main key for success with an epoxy garage floor coating is preparation of the concrete surface. Any petroleum based products that have stained the floor need to be completely cleaned with a degreaser before application. If you don't, the epoxy can not bond and will lift within a very short time. To see if the floor is completely cleaned use the water bead test. Spray a light coating of water on the surface and see if it beads up. Where ever it does you have a contamination problem which must be removed.
Epoxy does not work on asphalt surfaces because of the inherent plasticity even after the asphalt is cured. This slight movement cracks the epoxy and allows it to lift off the surface.
