A Simple Plan: Experts

Guide to Asphalt Maintenance When it comes to asphalt maintenance, there are four important aspects to consider. When water penetrates into the asphalt base, then this is the primary cause of the failure of asphalt. 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. There is movement in the pavement’s base material when water slowly seeps into the base through the cracks. The surface of the pavement will then show a grid-like cracking. 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. With a back hoe and saw-cutting, you can remove a portion of the pavement. Grinding machines can also be used for this purpose. When the old asphalt is removed, it is then replaced with new asphalt. Whatever method of removal you use will determine the amount that is removed. The depth of removal should be 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. The amount of removal should be extended a foot past the area that failed. An affordable method of maintenance is using asphalt overlay which provides a new wearing surface. If you are going to do an asphalt overlay you should consider certain important factors. 2.5 inches should be the maximum thickness of your overlay, and 1.5 inches for its minimum thickness. Grinding down the pavement should not be done on the overlay section so that he existing structure will be matched. 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.

Inlay and pulverize in place are also areas of asphalt maintenance. This is accomplished using a milling machine. During the inlay process, a depth of the existing asphalt is removed. This depth is many times a previous overlay. The contractors will then put the asphalt 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. The even black coating asphalt comes from this seal coating.
