How is Asphalt Maintenance Done? Maintaining an asphalt pavement involves four important areas. Water penetrating into the asphalt base is the main cause why asphalt begins to fail. Asphalt gets brittle and dry in the course of time, and when this happens the material wears away and begins to crack which then allows water to seep 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. Soon the pavement will crack and when this happen you should either replace the old asphalt or patch repair it. Isolated areas of the pavement are dealt with in patch repair. With a back hoe and saw-cutting, you can remove a portion of the pavement. A grinding machine can also be used. 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. You should remove asphalt to a depth of 1.5 times the original thickness of the asphalt. You should replace the base sock so that it matches the adjacent areas to allow for a uniform base support. Your should remove asphalt up to 12 inches past the area that has failed. Asphalt overlay maintenance is affordable and provides a new wearing surface. There are certain factors that one needs to be aware of when dealing with asphalt overlay. The overlay should have a maximum thickness of 2.5 inches and a minimum of 1.5 inches. When you are considering where to grind the existing pavement down, do not grind down the overlay section to match the existing structure. This can weaken the overlay strength if you do it. They will grind the existing pavement down to where they meet flush together to prevent this.

Another aspect of asphalt maintenance is to inlay and pulverize in place. This is accomplished using a milling machine. You remove existing asphalt when you do the inlay process. This depth is many times a previous overlay. Then asphalt is put back to the pre-inlay elevation. The method of pulverize-in-place will reduce all of the asphalt to particles that are base-rock size.

Seal coating is an important part of extending the life of asphalt and it should not be overlooked. Seal coating is a mixture of mineral fibers, emulsified asphalt, and water along with other admixtures. 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 is where the asphalt gets its even black coating.
