What Causes Asphalt Damage?

Potholes are a common issue in road surfaces and are caused by a variety of factors:

Water Penetration

The most significant cause of potholes is water penetration into the asphalt through cracks. When water gets underneath the surface, it weakens the base and soil beneath. This process is exacerbated in colder climates where freeze-thaw cycles occur. The water expands when it freezes, further enlarging the cracks and weakening the asphalt. When the ice melts, it leaves gaps beneath the surface, and the asphalt collapses into these gaps, forming potholes.

Traffic Wear

Continuous traffic, especially heavy vehicles like trucks and buses, puts a significant amount of pressure on asphalt. Over time, this pressure can cause the asphalt to weaken and break down, especially if there are already small damages or weaknesses in the pavement.

Aging and Lack of Maintenance

As asphalt ages, it loses its flexibility and becomes more brittle, making it more susceptible to damage. Regular maintenance like sealing cracks and sealcoating can extend the life of a driveway or parking lot, but without it, surfaces are more likely to develop potholes.

Poor Quality of Pavement Installation

If the paving contractor who initial installed the driveway or parking lot did not install it correctly it can cause premature potholes. It might not have the necessary strength or flexibility to withstand the demands of traffic and weather. Poor compaction of the base layer, inadequate thickness of the pavement, or low-quality materials can all contribute to the early formation of potholes.
Understanding these causes is crucial for effective prevention and repair of potholes, ensuring safer and smoother roads.

Can Damage to Asphalt be Prevented?

Damage to asphalt can be prevented to a certain degree. Asphalt does have a lifespan, so at a certain point asphalt will fail, regardless of preventive maintenance.  Here are key strategies to prevent asphalt damage:

Regular Maintenance

Regularly inspecting and maintaining asphalt surfaces is vital. This includes filling cracks, sealing surfaces, and repairing small damages before they become larger issues. Regular maintenance can significantly extend the life of asphalt and prevent more severe damage.

Proper Installation

Ensuring that asphalt is correctly installed is critical. This includes proper grading, ensuring adequate drainage, using high-quality materials, and ensuring the asphalt layer is the appropriate thickness for the expected traffic load.


Applying a sealcoat to the asphalt surface can protect against water infiltration, UV rays, and chemical spills. Sealcoating also restores the dark black appearance of the asphalt, making it look new again. It’s recommended to apply a sealcoat every few years depending on traffic and weather conditions.

Water Drainage Management

Good drainage is essential to prevent water accumulation on the asphalt surface. Water should be directed away from the pavement to prevent it from seeping into and weakening the base layers.

Addressing Water Penetration

Quickly repairing any cracks or holes in the pavement is crucial to prevent water from penetrating the surface and weakening the base or subgrade.

Traffic Management

Heavy vehicles exert more pressure on asphalt surfaces. Limiting the access of excessively heavy vehicles or distributing the load over a larger area can reduce stress on the asphalt.
By implementing these preventive measures, the longevity and performance of asphalt pavements can be significantly enhanced, reducing the need for frequent and costly repairs.

How Do You Patch Asphalt?

Asphalt patching is a serious aspect of pavement maintenance, providing various methods to address different types of damage. In San Jose, EARTHTEK Paving specializes in the following asphalt patching techniques:

Cold Asphalt Patching

This method is typically used for temporary fixes, particularly in cold climates or during emergencies when immediate repairs are necessary for safety reasons. The process involves filling the damaged area with cold mix asphalt and compacting it to level the surface. While not often used in San Jose due to the year-round operation of asphalt plants, it's an effective solution for urgent repairs to address immediate hazards.

Skin Patches

Skin patching is employed for minor surface damage where the top layer of asphalt has deteriorated but the base layer remains stable. It's a semi-temporary, cost-effective solution for small areas of distress. Skin patches are more durable than cold patches but are usually considered a stopgap until more comprehensive repairs or renovations are conducted.

Infrared Asphalt Repair

This method involves blending new asphalt with the existing material, creating a seamless, thermally bonded repair. It's a permanent solution suitable for cases where the base is not extensively damaged. Infrared asphalt repair is environmentally friendly and minimizes disruption, making it an attractive option for many customers.

Full Depth Reclamation Asphalt Repair

This more extensive repair method involves removing damaged sections of asphalt, repairing or replacing the base materials, and then filling the area with new asphalt. It is ideal for situations where both the pavement and base structure have significantly failed. This method restores the structural integrity and functionality of the pavement, offering a long-term repair solution.

Each of these methods has its specific applications and benefits, and the choice depends on the extent and nature of the asphalt damage. EARTHTEK Paving carefully assesses each situation to recommend the most appropriate and cost-effective repair method for your pavement needs in San Jose.
