Guide to Asphalt Maintenance When it comes to asphalt maintenance, there are four important aspects to consider. Asphalt begins to fail when water penetrates into the asphalt base. In the course of time, the asphalt will become brittle and dry with the aggregate starting to wear away and this causes cracks that will let water penetrate into the base of the pavement. So when water seeps into the cracks, it causes the base material to move and settle. This results in a grid-like cracking on the surface. When the pavement begins to crack then there are only two options to take, and these are either to replace the old asphalt or patch repair it. Isolated areas of the pavement are dealt with in patch repair. You remove a potion of the pavement using a backhoe and saw-cutting. Grinding machines can also be used for this purpose. Replacing the old asphalt that was removed by new asphalt is the next step. Whatever method of removal you use will determine the amount that is removed. The depth of removal should be one and a half times the original thickness of the asphalt. In order to have a uniform base support, you should replace the base rock so that it matches the adjacent area. The amount of removal should be extended a foot past the area that failed. Asphalt overlay maintenance is affordable and provides a new wearing surface. Before dealing with asphalt overlay, there are certain factors that you need to be aware of. The maximum overlay thickness should be 2.5 inches and the minimum is 1.5 inches. Grinding down the pavement should not be done on the overlay section so that he existing structure will be matched. The overlay strength could be weakened if you do this. To prevent this they need to grind the existing pavement down to where they meet flush together.

Inlaying and pulverizing in place is another aspect of asphalt maintenance. A milling machine is used to accomplish this. A depth of existing asphalt is removed during the inlay process. This is many times a previous overlay. The contractors will then put the asphalt back to the pre-inlay elevation. Pulverize in place method reduces all of the asphalt to base rock sized particles.

If you want to extend the life of asphalt, then seal coating is important and should not be neglected. Mineral fibers, emulsified asphalt, water, and other admixtures are combines to make up the seal coating. In order to prevent water from penetrating the pavement surface, it is important to seal coat the top layer of the asphalt and this will protect the top layer from wear from sun exposure and oxidation. This gives the asphalt its even black coating.
