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.

Paving contractors are skilled and experienced construction professionals responsible for the installation of pavements and asphalting of roads, driveways, walkways, and patios, among many others. They propose business plans for the structures and present accurate price quotes. Once approved, paving contractors will then hire other contractors, subcontractors, equipment, and workers for a given project. Paving is part of almost all of the different phases and types of construction.
Paving contractors can give you free estimates on how much you will spend on any surface that needs paving such as walkways, patios, driveways and parking lots.

The origin of paving can be traced back in 5600 BC when the first concrete structures were built. After a couple of thousand of years, the Egyptians began making and using bricks for the pyramids while the Chinese used cement-like materials in constructing the Great Wall. Eventually other ancient civilizations caught on with using stones and bricks to construct streets, buildings and houses. The Romans discovered the use of pozzolana cement from Pozzuoli, Italy to build several famous Roman structures such as the Appian Way, the Roman Baths of Caracalla, the Basilica of Maxentius, and the Coliseum, among many others. In the United States, cobblestones were the first materials used in paving. It was only in 1818 that hydraulic cement was discovered by Canvass White.
Paving workers such as bricklayers, cementers and finishers have been around since the time coinciding with the first use of concrete in ancient times. Similar procedures still apply nowadays but many paving workers also have to learn how to use pavers, paver finishers and asphalt finishers, among other equipment. Engineering vehicles have made most paving projects easier and faster compared to the old ways in the past.
When shopping around for a paving contractor, you can find referrals at most local construction companies and also online. You can also ask friends and colleagues for referrals based on their experience to make sure that the job will be done right.
