There are different asphalt problems that you may encounter on your own driveway. This means that each type of asphalt problem also needs a specific kind of repair method. Knowing what type of asphalt problem you have would lead you to know which type of asphalt repair you would need to perform. Once this is determined, you would know which tools, technique, and materials are to be used to correct the issue. Finding the correct materials will be easy as these can be found in different DIY stores. However, the tool and technique are different matters. But, if you are confident that you can repair your asphalt on your own, then here are the different kinds of repairs that you can do.
Skin patching can be used to repair raveling, depressions, or potholes. Before you start filling the holes, make sure that the area is clean and dry. An asphalt emulsion also needs to be applied before you can start installing a new asphalt layer on it. When doing this, you have to make sure that the materials used are still hot, spread over the proper elevation, and is compacted with the right tool that is needed to do the job properly. After installing your asphalt repair, you can then seal it. Potholes repair may be a little different, but it will also go through the same process.
Removal And Replacement
There are times that the asphalt problem you have will require more than just repairing it. This means that you will have to remove the asphalt layer and replace it. The removal of the top layer of the asphalt and replacing it with a new one is best suited to correct slippage cracks. On the other hand, to correct block cracks, rutting, and alligator cracks, you may have to remove the entire thickness of the asphalt layer. Sever problems likes an unstable base would require the removal of the entire asphalt down to its subgrade. When doing a removal, it is always important to remember that the layers removed should be done neatly. You have to extend an inches or two outside the area of the damage. The thickness of the asphalt replacement should be determined by the amount of traffic that goes over the surface. A professional asphalt repair company will be compacting each layer of the asphalt, and you should too.
If your asphalt does not really have a visible base failure, resurfacing can be done to prolong its life. This can be the most cost-effective way to go. When doing this, you have to make sure that the surface is clean and clear of any debris and vegetation. Once this is done, the surface should be applied with a tack coat so it is prepared for asphalt resurfacing. The resurfaced asphalt should have a minimum of 1.5 inches of thickness.
Pavement Reinforcement Fabric
If you are experiencing reflective cracking, then the best way to have this corrected is through pavement reinforcement fabric. This may cost a little bit more than usual, but the cost is justified by its water proofing benefits and retardation of the cracking. If this is the type of repair that needs to be done on your asphalt pavement, then it is best to have a contractor do it for you as this needs to be done with the proper tools, materials, and training. The fabric needs to be installed with the used of a heavy tack coat. It is then spread by hand or with the use of a machine. This would depend on the severity of the cracking. Once the fabric is spread over, it will be combed to make sure it is in contact with the tack coat applied. There should be no creases or wrinkles that are visible. It should be flat. After this process has been done, the layer will then be ready for paving.
To prevent water infiltration, it is a must that you do regular crack filling. This will slow down the spreading of the damage. Whenever you are filling a crack, it is a must that you make sure the crack is free of any dirt and debris. It should also be totally dry before applying a filler. You can either band the crack leaving two or three inches of band over the crack, or you can create a reservoir for the filler. The reservoir can be done by widening the crack.
Sealing an asphalt is not really necessarily done every year or every other year. Doing this will only lessen the lifespan of the asphalt. You should consult the professional on when you can re-apply a sealant on your pavement. When doing this, you have to make sure that the surface is clean and dry. If you see grease and oil spots on your driveway, then it has to be treated before you apply a sealant. Before applying the sealant, it is a must that you read the manufacturer’s instructions to do it with success.
Preventive maintenance would be the best way to go if you want to avoid irreversible damage to your pavement. This means early detection of the problem or repairing minor damage at first chance. This will help avoid any damage that will cause you several headaches, which will only damage your bank account.
