Three Driveway Problems And How To Fix Them
A properly paved driveway adds value to your home and is durable and useful. However, most homeowners will run into driveway problems at one point or another. Common driveway pavement issues include cracking, breaking, and softening of the material. Over time, chemicals such as oil and gasoline can cause your driveway to deteriorate. In some cases, you can take a do it yourself approach. Other times, it's necessary to contact a professional. Here are three common driveway pavement issues to look out for.
Asphalt can sometimes become vulnerable to what's called raveling. This refers to the progressive separation of the hot mix asphalt layer. It starts at the surface and moves downward. The issue often begins when the fine aggregate starts to wear away, causing the surface of the pavement to develop pock marks. If left untreated, the continued erosion creates larger particles that completely separate. The result is a jagged appearance that causes that pavement to become rough instead of smooth. To correct this, you have a few options. You can apply a layer of hot mix, or you can apply a layer of chip seal.
Pavement rutting is another frustrating problem home owners face. Rutting is when the surface of the pavement develops a depression in the wheel path. It occurs due to compression, loading, or design issues. It's particularly noticeable when it rains and the depressions fill with water. Some depressions are rather deep, while others are shallow. Rutting can also cause the pavement to begin to separate so that not only is the pavement depressed, but it's appearance has numerous unsightly cracks. In most residential cases, the rutting is minor. If this is your case, you can fill in the depressions with overlay material. Severe rutting requires a professional to remove the affected area and replace it with compatible material.
Cracks that occur in a flexible overlay of a rigid pavement are referred to as reflection cracks. These types of cracks occur directly over an existing crack. The reason this happens is because when you place asphalt overlays over cracked pavements, the existing structure will reflect in the surface pavement over time. To make matters worse, water can seep through the cracks and allow water to penetrate the underlying layers causing damage and deterioration. If the cracks are less than 1/2-inch, you can seal them to prevent moisture from seeping through and causing further deterioration.
