What is an asphalt overlap?

Asphalt overlap is another layer of asphalt that covers imperfections in the existing asphalt. Asphalt overlays are commonly applied to driveways, parking and sidewalks that have minor damage, such as cracking of light, slight deterioration or slightly sunken areas. The asphalt overlap process usually involves balancing the shape of the old asphalt, which ensures a smooth, even surface to which other layers can be added. This ensures that asphalt overlap corresponds to the height of the door, threshold values ​​of garages, roads, sidewalks and curbs. A special primer is then applied to the surface; This primer acts as an adhesive that provides the second layer of asphalt to the first. At this point, a crushed stone may be necessary to further ensure the level of asphalt overlap. Once the stone is compressed and classified, the tiles. The overlap of asphalt concrete is poured over the original layer, primer and crushed stone. Butt joints ensure that the asphalt meets the circuits of the area and remains at the level. JIf it is dried, the overlap has an elegant and smooth look that is free of defects.

When preparing for asphalt concrete overlap, it is important to keep in mind several considerations. First, it is important that damage to the original layer is not too deep. If so, the second layer simply penetrates the cracks and indentation of the foundation and the problem remains unresolved. Secondly, drainage of an area to be paved. All surfaces must have a drain to excess water, and if this step is overlooked, the water could rush uncontrolled to the houses, garages, yards and streets

At present, there are special products on the market that are specially designed to increase the appearance of asphalt overlap. One such product is a cover similar to a matrix, which is installed via the original layer before the asphalt pavement is stored. This layer is made of special fibers, is designed to absorbIt beat excess water and maintained a smooth look, extended the life and appearance of overlapping.

While asphalt overlays may be required to repair the damaged surface, there are ways to avoid investing in this process first. One of the most important is maintaining the surface level regularly by filling up cracks and potholes. Guaration that the right drainage areas are installed or create other output routes for excess water, and also helps to avoid the need for overlapping in the future.
