5 Asphalt Problems and How to Manage them

/, Asphalt Driveways/5 Asphalt Problems and How to Manage them

Asphalt is a fantastic surfacing material but like any other building material, it is subject to problems as a result of wear and tear, improper installation, and damage from the elements. In this article, Asphalt Contractors look at 5 common asphalt problems and the solutions available.


Probably the most easily recognisable asphalt problem, potholes are caused by moisture infiltration and untreated cracking. When cracking is severe, small chunks of asphalt become lose and break away as vehicles or other heavy objects move over the surface. Treatment for this condition requires removing all of the affected concrete (including the cracked areas surrounding it), re-compacting the sub layer and then placing fresh concrete over the top. It’s possible to fix potholes through a DIY method but for large scale problems, it’s better to call in a professional repair team.

Edge cracks

These are the cracks which run parallel to the edge of the asphalt and are caused by the base materials weakening through poor drainage or a lack of support. Vegetation and heavy traffic can also cause this type of cracking. Minor edge cracking is relatively easy to repair yourself with a commercially available sealant or filler. Ensure you remove any surrounding vegetation and thoroughly clean the cracks before attempting a repair. some tips to protect your asphalt driveways


Depressions generally occur when water enters through the cracks in the asphalt and enters into the base (lowest) layer of the pavement, causing it to shift and resettle unevenly. This problem if most obvious when it rains and puddles form in the depressions and the pooling water causes even greater damage to the base layer. A surface patch or professionally done infrared patch (where the asphalt is liquefied, scarified, and patched up with virgin asphalt) approach can be used to fix a mild depression however if the base layer has been seriously compromised, resurfacing is the only option.

Slippage cracks

These repeating crescent shaped cracks are caused when the upper layers ‘slip’ over the course underneath. The movement is due to a lack of bonding between layers which can be caused by improper installation or contaminants like oil and dirt entering through cracks. Asphalt damaged by slippage needs to be removed and replaced through partial or full depth patching (where the upper layers of concrete are removed, the sub base is re-compacted and primed, and fresh concrete is placed on top).
