Servicing and Maintenance Methods Used By Asphalt Contractors
Servicing and Maintenance Methods Used By Asphalt Contractors Upon asking the asphalt contractors, you’ll come to know that the maintenance of this material can be divided into four different parts. One of the biggest reasons why this stuff fails prematurely is the penetration of water into the base. With continued penetration, the base becomes brittle and dry and with the passing time, it begins to wear away and develops cracks. These cracks increase with the amount of water getting into the base and with it, the speed too increases and cracks too, appear much faster than usual. The crack pattern is grid-like and once, this stage is achieved, there are just two options left. They are – Patch repairing Replacing the older one
Patch Repair According to asphalt contractors, this method can be useful only when there are some isolated patches of cracks. With the help of backhoe or a saw, these patches are removed and you’ll find several contractors using the grinding machine. Once the older one is removed, they replace it with the fresh coat.

If you are DIY, make sure that the removal depth should be equal to 1.5 times the original thickness of the base. In some odd cases, you’ll have to remove the base rocks too for matching the adjacent areas, so that new base can support uniformly. Moreover, keep in mind that the amount of removal should be extended 12 inches past the area that has failed. Overlaying The next method recommended is overlaying and the biggest USP of this version is that it is very affordable. Moreover, with this process, you can give that area a completely new wearing surface. However, to make sure that it performs well, you need to be aware of certain factors described below. Overlay thickness should be a maximum of 2.5 inches with the minimum of 1.5 inches. While considering the area to grind, avoid grinding the overlay section for matching the existing structure as doing this will weaken the strength of the entire overlaying. Therefore, it’s recommended that you hire the services of asphalt contractors as they’ll grind the existing payment down to where they meet flush together to prevent this. Inlaying and Pulverizing in Place Both the processes are done using the milling machine. In inlaying, it removes the depth of the existing asphalt and in most cases; it is the previous or older overlay. With its help, the team can put it back in the pre-lay elevation.

Seal Coating This is a very crucial step taken to increase the life of the construction. The material used for coating is generally a mixture of mineral fibres, emulsified asphalt and water along with other admixtures. With its help, the topmost layer is sealed to give it a shield to prevent water from penetrating inside the surface. It will also protect it from the wear caused by sun’s exposure and oxidation.
