When you look at the maintenance of asphalt, it can be divided into four areas. The main cause of asphalt failure is the penetration of water into the asphalt base. Overtime becomes brittle and dry when the unit starts to wear off and cause cracks that will allow water to penetrate the base of the pavement. When water sees a crack, it causes the base material to move and settle. This leads to cracking of the surface on a pattern that is mesh. When the payment has reached this stage, there are only two options that replace the old asphalt or correct its correction.
Repair fixes
He deals with isolated areas. With the help of an excavator and cutting the sidewalk is removed. They can also use a grinding machine. After removing the old asphalt, it is replaced by a new asphalt. The delete method determines the amount to delete. The depth of removal should be equal to one point five times the original thickness of the asphalt. You may also need to replace the base rock to match adjacent areas to provide support for basic support. The removal volume must be extended twelve inches below the area that failed.
Asphalt pavement
This asphalt maintenance is affordable and provides a new, wear-resistant surface. When working with asphalt overlay there is a certain factor that you should be aware of, including:
• The thickness of the overlay - it should be no more than two points five inches with a minimum point of five inches
• Smooth transitions - when you consider the possibility of crushing an existing sidewalk, remember that you do not need to grind the overlay section in accordance with the existing structure. If you do this, it will reduce the strength of the overlays. They will shred the existing payment to the point where they come together to prevent it.
Inlay and spraying on site
Both of these areas of asphalt maintenance are performed using a milling machine. In the process of inlay, it removes the depth of the existing asphalt, which is many times higher than the previous overlay. This will allow contractors to return the asphalt to the preliminary incrustation. The on-site grinding method will reduce all asphalt to particles that are base sizes.
Compaction
This is an important part of extending the life of asphalt, and cannot be ignored. The sealing coating is a mixture of mineral fibers, emulsified asphalt and water along with other additives. This will seal the top layer of asphalt to prevent water from penetrating the road surface and protecting the top layer from wear from sun and oxidation. This is what gives asphalt even its black surface.
