Major Causes of Asphalt Pavement Deterioration

Oct 11, 2022

Asphalt parking lot and asphalt driveway pavement offers numerous benefits, which include strength and durability. However, even the best quality asphalt pavement can fail over time. Discover some causes of asphalt pavement damage and how to protect against the issues.


Cracks

Cracks are a common cause of asphalt pavement deterioration. A range of aspects can contribute to the formation of cracks.



Aging

Asphalt pavement has had continual stress from vehicles and other elements over the years. Finally, when the pavement can no longer withstand this stress, cracks start to form. Therefore, if your pavement has served you for years, consider a replacement before cracks form.



Moisture Damage

Water is one of the biggest enemies of asphalt pavement. Moisture can seep deep into the asphalt and cause the materials to break. The sand and gravel start to move and settle, which causes the pavement to crack. Inspect your pavement regularly for cracks and water damage. If you notice any problems, repair them as soon as possible to avoid further deterioration.


UV Damage

The ultraviolet (UV) rays from the sun can also cause damage to asphalt pavement. The UV rays break down the materials in the asphalt and make the surface more susceptible to cracking and deterioration. To protect your pavement from UV damage, seal it regularly with a quality sealant.



In the same way, extreme cold can cause freezing and thawing, damaging the asphalt.


Potholes

Potholes in asphalt parking lots form when water seeps into cracks in the pavement and freezes. The expansion of the water causes the cracks to become bigger, which leads to chunks of asphalt breaking off. These chunks create a hole, or pothole, in the pavement.


You can fix this problem by patching the holes with new asphalt. However, if the damage is extensive, you may need to replace your pavement.


Oil and Gas Spills

When oil and gas spill onto asphalt driveway and parking lot pavement, the oil seeps into the surface and weakens the materials. This issue makes the pavement more susceptible to cracking and deterioration.


To prevent oil and gas spill damage, clean the mess as soon as possible. Use a high-quality cleaner designed for asphalt to remove the oil and gas from the surface.


Ruts

Ruts form when vehicles continually travel over the same spot on the pavement. Your pavement is more susceptible to ruts if it lacks adequate thickness or if you use incorrect asphalt mixes. Additionally, ruts may occur due to moisture damage or settling.



If you notice ruts in their initial stage, you can repair them by filling and overlaying the affected area. However, if the ruts are severe, you'll need to replace your pavement.


Tree Roots

If trees or shrubs are next to your asphalt pavement, their roots can cause problems. The roots can grow underneath the pavement and lift it, which creates cracks and holes on the surface.



Watch the distance between the trees and your pavement to prevent this issue. If their roots already cause problems, remove the roots or mill out the affected pavement area.


Improper Installation

Even the best quality asphalt pavement will fail with improper installation. Proper installation involves grading the surface correctly, preparing the subbase and subbase binding, laying the surface, and smoothing it out. If any of these steps are not done correctly, this can lead to premature cracking and deterioration.


Therefore, only hire a reputable contractor with experience installing asphalt pavement for a quality guarantee.

Asphalt paving is important in constructing and maintaining roads, driveways, and parking lots. It is a low-cost, long-lasting material that withstands heavy traffic and extreme weather conditions. But a few common mistakes can be made when paving with asphalt, leading to a weak surface that only lasts for a short time. Here are some of the most common blunders to avoid when paving with asphalt. Inadequate Base Preparation The asphalt surface will probably crack and get holes over time if it is not leveled or packed down well. The base must be excavated to a specific depth and width before the asphalt can be laid. The base material should mix crushed stone, gravel, and sand to provide a stable and long-lasting foundation for the asphalt. Then, this material should be leveled and pressed down with a roller to make a smooth, stable asphalt surface. Using the Incorrect Asphalt Mix The asphalt mix is made by mixing asphalt cement with a certain amount of aggregate, such as crushed stone, gravel, or sand. The ratio of aggregate to asphalt cement will change based on how the surface will be used and how much traffic it will get. When the wrong mix is used, the surface becomes weaker and more prone to cracking and damage. A mix that is too heavy on aggregate and too light on asphalt cement, for example, will not provide enough stability and will crack under heavy traffic. A mix that is too heavy on the asphalt cement and too light on the aggregate, on the other hand, will be more prone to rutting and deformation. Not Properly Compacting the Asphalt After laying the asphalt, it should be compacted with a roller. Compacting the asphalt removes air pockets and ensures a smooth and stable surface. Asphalt that has not been properly compacted is more prone to cracking and shifting. Compaction should be done in multiple passes, beginning with a light pass to remove any air pockets, followed by heavier passes to ensure a smooth and stable surface. The installer should move the roller slowly to ensure the asphalt is properly packed. Leaving the Asphalt Unsealed Sealing the asphalt will protect it from the elements and extend its life. A seal coat is a thin layer of asphalt that is poured over the asphalt. This liquid asphalt layer will shield the surface from water, oil, and UV rays. If the asphalt is not sealed, it is more likely to crack and be damaged by water, oil, and UV rays. The seal coat should be applied a few months after asphalt installation to let the asphalt fully cure. Not Using a Professional Asphalt Contractor Hiring a contractor who isn't qualified or doesn't have enough experience can lead to bad work, a weak surface that doesn't last long, and even expensive repairs or complete repaving. However, a professional contractor will know how to prepare the foundation, use the right mix, pack down the asphalt, and seal it. Working with a professional contractor ensures all permits and inspections are in place and that the work is done according to local rules and codes. They will also have all the tools and resources they need to do the job well and quickly. Look no further than J & B Asphalt & Paving for professional asphalt paving services.
