Asphalt Repair, Raleigh NC
When pavement is damaged it should be repaired immediately so that it doesn't spread further into the blacktop. When cracks occur in the surface water and chemicals will penetrate into the asphalt and cause it to break down more rapidly. Depending on the damage the pavement may need to be cut out in the damaged area in order to fix the foundation for a solid base and then replace the area with new asphalt. Caused by an improper foundation and drainage system. This cracking is known as crocodile cracking because of the resemblance to the scaly back of a crocodile. Proper drainage plays a large part in the role of prevention from erosion. Meaning, if you have proper drainage so that water doesn’t sit under or on top of the pavement you will preserve the longevity of the asset. Call today and our experts will determine the extent of the damage and give you an exact plan to rectify the damage.
Considerations In warm climates, your asphalt will start to oxidize leading to cracked surfaces. Oxidation is due to direct UV Rays, or sunlight. In cold climates, frost will cause the driveway or parking lot to up-heave and settle leading to cracked surfaces. This is why proper drainage before installation of the pavement is vital. Vehicles will also cause potential damage to the blacktop. Depending on the amount of traffic and drainage under the surface the pavement will become fatigued and start to crack. However, though traffic is heavy, seal-coating is not used on major roads. This is because the extreme amount of traffic that the roads experience on a daily basis reinforces the structure of the blacktop. Although in some cases, like in rural areas, the roads often do not get enough traffic to reinforce the road to the same extent as it does in urban areas. Because of this, major roads can often be seen with cracks and damage just like a driveway or parking lot would. |

Even in cases like this, a driveway sealer is seen as unnecessary on the roads, because the traffic is still for the most part constant and the coating doesn’t last on these roads. The similarity between driveways and parking lots, although many of them do have constant traffic, the vehicles are sitting for long periods of time, and the water, oil and sunlight is directly hitting the same areas consistently each day. This constant exposure to the elements in the same areas of the driveway or parking lot is what leads to damage. Before this damage begins to take place the asphalt changes colors, from a deep black to a warn out gray. If your asset has a gray appearance, then it is time to seal the blacktop. This gray color, either means that your current seal needs to be redone, or the materials in the asphalt are beginning to wear down and you need to fill in the cracks and coat the surface. Any cracks will allow water in more easily, which would mean that if not treated it would simply continue to decay, and eventually lead to crocodile cracking. The process of filling in the cracks makes them unnoticeable because of the deep black color of the coating, which is also part of the appeal. The coating gives a fresh look to your driveway or parking lot. Keeping a fresh aesthetically pleasing appearance, as well as its durability are two important components with any driveway or parking lot and are both factors that a seal-coat will improve.
