5 root causes of pavement cracking

Cracked pavement is a common issue that many property owners face, with consequences that extend beyond mere aesthetics. Cracked pavements can pose safety hazards, reduce overall property value, and even lead to further structural issues if left unaddressed. Understanding the causes of pavement cracking is essential for taking preventive measures, performing proper maintenance, and ensuring the longevity of your paved surfaces.

With all of this in mind, we have compiled this informative guide to help you understand the root causes of pavement cracking and how you can address them effectively.

Reason 1: Poor Construction, Material Quality, and Drainage

The foundation of any pavement project lies in proper construction techniques and high-quality materials. Subpar construction and poor-quality materials can lead to premature cracking and a reduced pavement lifespan. Additionally, a well-designed drainage system is crucial for preventing water damage to your pavement. To avoid these issues, choose a reputable paving contractor that uses high-quality materials and ensures proper drainage during the construction process.

Reason 2: Freeze-Thaw Cycles and Water Damage

The effects of winter, temperature fluctuations and water penetration are significant factors contributing to pavement cracking. Freeze-thaw cycles occur when water seeps into pavement cracks, freezes, and expands, causing the pavement to crack further. Poor drainage exacerbates water damage, making it essential to address any drainage issues promptly.

Preventive measures, such as using sealants and ensuring adequate drainage, can help minimize freeze-thaw cycle-related cracking and water damage. Regularly inspect your pavement for cracks, and fill or seal them as soon as possible to prevent water from infiltrating and causing further damage.

Reason 3: Heavy Vehicle Traffic and Overloading

Heavy vehicle traffic and overloading can take a toll on your pavement’s integrity. Excessive weight from vehicles can cause cracks and other structural issues, particularly if the pavement was not designed to withstand such loads. To minimize damage from heavy traffic and overloading, monitor vehicle weights, and adhere to weight limits set for your pavement. Consult with a professional paving company to determine the appropriate weight limits for your specific pavement type and thickness.

Reason 4: Tree Roots and Vegetation Growth

Tree roots and vegetation growth can cause pavement cracks as they expand and push against the pavement structure. To prevent damage from tree roots and vegetation, plan your landscaping carefully and install root barriers when planting trees near pavements. Regularly trim vegetation growing near pavements to prevent roots from infiltrating and causing cracks.

Reason 5: Insufficient Pavement Maintenance

Regular pavement maintenance plays a critical role in preventing pavement cracking and addressing drainage issues. Common maintenance tasks include seal coating services, pothole patching, and resurfacing, which can significantly extend the lifespan of your pavement. Consult with professional paving companies like Burnaby Blacktop for routine maintenance services tailored to your pavement’s specific needs.
