Understanding the Causes of Asphalt Pavement Breakdowns

Understanding the Causes of Asphalt Pavement Breakdowns


Pavement, the silent workhorse of urban infrastructure, undergoes significant wear and tear over time. Asphalt, while known for its durability and cost-effectiveness, is not immune to breakdowns. In Polk County, FL, where the climate and traffic can both be demanding on road surfaces, understanding the causes of asphalt pavement breakdowns is crucial for maintaining its integrity over the years. A. Rafferty Paving stands ready to address these challenges, offering expert solutions to keep your pavements in top condition.


1. Water Damage

Perhaps the most pervasive and damaging element to asphalt pavement is water. When water penetrates the asphalt through cracks or unsealed surfaces, it can erode the base, leading to potholes, fissures, and eventually, major breakdowns. Proper drainage and regular maintenance such as sealing cracks and ensuring the pavement is properly graded are vital in mitigating water damage.

2. UV Radiation

The intense Florida sun can have a significant aging effect on asphalt pavements. Ultraviolet (UV) rays from the sun oxidize the surface of the asphalt, making it brittle and more susceptible to cracking. Over time, this oxidation can degrade the pavement's quality, leading to a need for more frequent repairs or replacement. Applying sealcoating can protect the asphalt from UV damage, extending its lifespan.

3. Heavy Traffic

The weight and volume of traffic that a pavement endures can expedite its deterioration. Heavy vehicles, in particular, exert a tremendous amount of pressure on asphalt, which can cause rutting, depressions, and structural cracks. For roadways and driveways experiencing high levels of heavy vehicle traffic, using a higher-grade asphalt mix designed to withstand such pressures is advisable.

4. Poor Installation

A significant factor that can contribute to early pavement breakdown is poor installation. This includes inadequate compaction of the base material and asphalt, improper grading, and insufficient thickness of the asphalt layer. These oversights can lead to a host of problems, including premature cracking, pooling of water, and overall instability. Choosing a reputable and experienced contractor like A. Rafferty Paving ensures that your asphalt paving project in Polk County, FL, is done correctly from the start.

5. Temperature Fluctuations

Florida may be known for its warm weather, but it still experiences temperature fluctuations that can affect asphalt pavements. Thermal expansion and contraction can cause asphalt to crack and weaken over time. This is especially true for areas where temperatures can drop significantly during the winter months. Regular inspections and maintenance can help identify and address these issues before they lead to major pavement failures.

6. Lack of Maintenance

Regular maintenance is the key to extending the life of any asphalt pavement. Neglecting small issues like cracks or potholes can lead to larger, more costly problems down the road. Services such as sealcoating, crack filling, and patching potholes are essential in preserving the integrity and appearance of your pavement.
