What Causes Bitumen Driveway Damage?

Bitumen driveway cracking is either caused by wear and tear on the surface of the driveway or from issues below the top layer.


Damage From on Top of the Bitumen Driveway

The surface of your bitumen driveway takes all the wear and tear from vehicles and the elements. An excess of moisture or weight can lead to erosion and loosening of the surface.

Too Much Moisture

The pooling of moisture on the surface of your bitumen driveway can lead to water infiltrating the bitumen and separating the composite, leading to chipping and cracking.


Weight Overloading

Depending on the thickness of the driveway, your bitumen driveway may crack under excessive weight. Usual car traffic shouldn’t cause damage, but the weight of trucks and construction vehicles can overload bitumen, especially if they are parked on your driveway.


Damage From Below the Bitumen Driveway

Issues below the surface of your bitumen driveway can be hard to detect until you start to see the damage, and some of the problems may be out of your control.


Too much or not enough moisture in the soil below your bitumen driveway can lead to a change in the shape of the soil. This can cause the bitumen to be either unsupported or pushed up, resulting in cracking.

Tree Roots

Trees roots growing under your bitumen driveway can cause cracks by pushing the driveway up and causing it to expand beyond its limits. You’ll also see bumps and dips start to form in your driveway that can lead to water pooling.

Soil Erosion

The natural expansion and contraction of the soil caused by seasonal changes or degradation from another source can cause the soil beneath your bitumen driveway to shift, meaning that your driveway needs to shift with it. While bitumen driveways have some flexibility to move, a constant shift or a severe one can cause bitumen cracking.

Poor Installation

If the soil beneath your bitumen driveway is not correctly flattened and compacted before the asphalt is poured, your bitumen driveway will quickly start to crack as it struggles to cope with the shifting soil.


How to Prevent Bitumen Driveway Damage

Now that you understand the causes of bitumen driveway damage, you can start to prevent them from happening.

Reducing Overloading

Unless your driveway is capable of carrying heavy-duty vehicles, avoid using your bitumen driveway as an access point. If nothing can be done to avoid trucks using your driveway, try to reduce the frequency of use or parking a heavy vehicle on your driveway.

Provide Good Drainage

Install proper drainage from your bitumen driveway to reduce the amount of water pooling on the surface and seeping into the soil.

Driveway Cleaning

Regularly clean and sweep your driveway to remove debris, dirt and moisture that can cause chipping and cracks.


How to Repair Bitumen Driveway Damage

If you already have damage to your driveway and need bitumen driveway repairs, first you’ll need to evaluate how extensive the damage is.


Minimal Bitumen Cracking

If you’ve identified a few small cracks in your bitumen driveway, you may be able to fill the cracks with a driveway crack filter available from a hardware store. If you’re doing this make sure to follow the instructions that come with the product and we recommend applying a sealing coating after the crack filler has set.

If you want to remove the appearance of the crack filler and give your driveway and give your driveway a new look you can hire a bitumen driveway company to resurface your driveway.


Partial Bitumen Cracking

If your bitumen driveway has extensive cracking but just in isolated sections, you may be able to have the severely affected sections cut out and replaced, rather than getting your driveway completely reconstructed.  Speak to a bitumen driveway contractor to get professional advice on your situation.

Severe Bitumen Cracking

If your driveway has cracks throughout the majority of the bitumen, you may need to completely remove and reconstruct the driveway. This will allow the bitumen driveway professionals to inspect under the surface of the driveway to find the cause of the damage and address it.
