Why Does Asphalt Pavement Crack?

By: Daren AllPaving May 22, 2019

It is important to understand why  asphalt pavement develops cracks, in order to better address the problem and implement corrective measures before the problem gets worse.

Over time, sun and weather exposure as well as consistent pressure from vehicles, can contribute to damages and cracks developing on your asphalt surface. In cold weather areas, frost heave is a common issue due to the formation of ice underneath the surface which results in cracking of the asphalt and might lead to accidents on the road.

There are multiple factors that contribute to wear and tear on asphalt roads and pavement performance, such as:

  • Improper thickness.
  • Lack of maintenance.
  • Uneven base layer.
  • Weakened paver seams.

If the initial construction of the pavement was not measured and executed properly, the longevity of the asphalt is greatly reduced and can cause cracks to develop within months of installation.

On the other hand, heavy traffic in parking lots is one of the main causes for damages in pavement surfaces. This is due to the weight of cargo trucks crossing the parking lots.

Also, another reason why cracks appear is tree roots that grow and expand underneath the asphalt layers. This causes layer displacement on the surface and eventual cracking of the material, creating trip hazards and bumpy roads that cause damages to vehicles.

As asphalt experts, we suggest relocating (if possible) the tree that causes the root problem before applying any patching material to the surface, or not planting any type of big tree near the asphalt road or asphalt driveway.

How To Identify the Cause of Damage.

AllPaving offers professional asphalt services as well as free property evaluations, to determine what exactly is causing any cracks or damage to your lot. We will examine high-stress areas, identify potholes, uneven surfaces, as well as evaluate the foundation layer to ensure it was installed at the correct thickness and level.

If problems are identified, we will offer multiple plans of corrective and preventive action to bring your lot up to industry standards and restore its brand new appearance while also improving the longevity and structural integrity of the asphalt.

Cracks and potholes form due to uneven pressure and continue to become more apparent if left unattended or if the pavement layers were not installed incorrectly.

It becomes urgent to address any issues you identify in your lot quickly before the problem becomes larger and requires more expensive solutions, asphalt pavement crack repairs and large amounts of crack filler material.

Look for professional asphalt companies in your area to ensure your foundation is correctly installed, the pavement thickness is proper, and that the lot is maintained and well and taken care of in order to maximize its lifespan and minimize cracks, damages, trip hazards and thus liabilities.

Different Kinds of Pavements Defects.

  • Alligator cracking: This type of “fatigued” cracking mainly starts from a structural failure due to truck loading. First of all, this can happen due to the weakness of the road’s surface, its thickness in case it is very thin and a poor drainage system.
  • Slippage cracking: This issue is attributed to the displacement and deformation of the pavement surface that occurs as a result of the pressure of the wheels when braking or turning.

This occurs when there is a poor bond between the asphalt layers and the underlying layer of the pavement structure, since there is a lack of an adhesive or a low resistance surface mix. In some cases the joint can be weakened by dirt, oil or other contaminants in the ground.

  • Pothole: Usually this type of defect results as a consequence of not repairing cracked pavement in alligator shape. As soon as the cracks are found, pieces of pavement begin to come off and they can be displaced by the cars creating a hole in the surface that could end up penetrating the asphalt layer to the base. Furthermore, they can be the result of moisture infiltration. The good news is potholes can be easily solved with an asphalt patch.
