Asphalt pavement is a popular choice for roadways and parking lots because it is relatively inexpensive to install and maintain. However, asphalt pavement failures are common and cause accidents and inconvenience drivers and pedestrians. This blog post by Bay Country Contractors will discuss the most common pavement failures associated with asphalt and how you can prevent them from happening at your property in Alexandria.
1) Alligator Cracking
Alligator cracking is a type of pavement failure that occurs when the surface layer of asphalt separates from the underlying layer. This often happens when the surface layer has been over-compressed, which causes it to become brittle. Alligator cracking can be dangerous because it increases the risk of accidents and can also create potholes.
To prevent alligator cracking, you should ensure that your asphalt surface is not over-compressed and avoid driving or parking on it when it is wet.
2) Linear Cracking
Linear cracks are usually the result of pavement fatigue. This type of failure occurs when the asphalt pavement is subjected to repeated loads, such as traffic. Linear cracks can eventually grow and cause the pavement to fail.
To prevent linear cracking, you should ensure that your asphalt pavement is adequately designed and installed; this involves estimating the expected traffic load and the weather conditions. It would also help avoid driving or parking on it when wet.
3) Transverse Cracking
The movement of the underlying soil causes transverse cracks. Changing temperature cycles and poor construction due to improper paver operation are reasons behind transverse cracking.
To prevent transverse cracking, you should ensure that the sub-base is adequately compacted and that no excess moisture is present in the soil.
Potholes form due to water infiltrating the pavement and softens the underlying soil. The weight of traffic then causes the pavement to break up and create a hole.
To prevent potholes, you should ensure proper drainage in the area and that the sub-base is adequately compacted. You can also use a sealant to help protect your asphalt from moisture damage.
Depressions are pavement areas with lower elevations than the surrounding. Depressions are noticeable after rain when water fills them. Depressions can cause headaches to parking lot owners as vehicles visiting them can bump and hurt themselves on the road. Depending on the depression’s severity, you may have to remove and replace the affected area by applying a thin infrared patch.
By knowing what to look for and how to prevent pavement failures, you can help keep your asphalt pavement in good condition for years to come.
Pavement failure is a common problem that plagues asphalt. The most common failures are excessive cracking, fading color, and fatigue. Your parking lots and driveways can last for years with regular asphalt maintenance.
