Asphalt coatings are used to cover minor damage in driveways, parking lots, and pavements. The process involves leveling the old asphalt, applying a primer, crushed stone, and pouring asphalt concrete coating. Proper drainage and maintenance can prevent the need for coating.
An asphalt coating is an additional layer of asphalt that covers imperfections in the existing asphalt. Asphalt coatings are commonly applied to driveways, parking lots and pavement that have minor damage such as light cracks, minor deterioration or slightly sunken areas. The asphalt overlay process commonly includes a leveling of the shape of the old asphalt, ensuring a smooth, even surface on which to add additional layers.
After the small imperfections in the original asphalt have been filled, butt joints are typically used to ensure the base course remains level. This ensures that the asphalt coating matches the height of doorways, garage doorsteps, roads, sidewalks and curbs. A special primer is then applied to the surface; this primer acts as a glue that fixes the second layer of asphalt to the first. At this point, crushed stone may be needed to further secure a level asphalt roofing design. Once the stone has been compressed and leveled, paving begins. Asphalt concrete coating is poured over the original layer, primer and crushed stone. Butt joints ensure that the asphalt meets the perimeters of the area and remains level. Once dried, the coating has a smooth, smooth and flawless appearance.
When preparing to administer an asphalt concrete coating, it is important to keep a couple of considerations in mind. First, it is important that the damage to the original layer is not too deep. If it is, the second coat will simply seep into the cracks and indentations in the foundation and the problem will remain unresolved. Secondly, the drainage of the area to be paved should be considered. All surfaces must have an outlet for excess water, and if this step is neglected, water could run unchecked into homes, garages, patios and streets.
There are specialty products on the market today that are specifically designed to improve the appearance of an asphalt layer. One such product is a mat-like coating that is installed over the original layer before the asphalt pavement coating is laid. Made from special fibers, this layer is designed to absorb excess water and maintain a smooth appearance, prolonging the life and appearance of the upholstery.
While an asphalt coating may be needed to repair a damaged surface, there are ways to avoid having to invest in this process in the first place. Maintaining a level surface by regularly filling cracks and potholes is one of the most important. Ensuring that adequate drainage areas are installed or creating additional outlet routes for excess water also helps avoid the need for a cover in the future.
