Common Causes of Asphalt Cracks

Understanding Asphalt Cracks

Asphalt is a popular material commonly used for driveways, roads, and parking lots due to its durability and cost-effectiveness. However, over time, cracks can develop on the surface of the asphalt, compromising its integrity and aesthetics. It is important to understand the common causes of asphalt cracks to prevent further damage and maintain the longevity of the pavement. Complement your reading with this recommended external website, packed with supplementary and pertinent details on the topic. Asphalt Crack filler, uncover fresh information and intriguing perspectives.

Poor Installation

One of the leading causes of asphalt cracks is poor installation. When asphalt is not installed correctly, it can result in weak spots and uneven surfaces, making it more prone to cracking. Proper preparation of the base, correct asphalt compaction, and adequate drainage systems are crucial during installation to ensure the pavement’s durability.

Heavy Traffic

Areas with heavy traffic, such as highways and busy intersections, are prone to developing cracks in the asphalt due to the constant weight and pressure from vehicles. The repetitive stress and load can eventually lead to fatigue cracking, where the asphalt begins to break apart and form a series of interconnected cracks.

Extreme Temperatures

Another common cause of asphalt cracks is exposure to extreme temperatures. During hot weather, the asphalt can expand, and during cold weather, it can contract. These continuous temperature fluctuations weaken the pavement’s structure, leading to cracks over time. Additionally, water seeping into these cracks can freeze and expand, exacerbating the problem.

Poor Drainage

Adequate drainage is essential to prevent water from accumulating on the asphalt surface. When water is not properly drained, it can seep into the cracks and weaken the underlying layers of the pavement. This can result in further cracking and deterioration of the asphalt, especially during freeze-thaw cycles.

Aging and Lack of Maintenance

Asphalt, like any other material, deteriorates with age. With time, the binder that holds the aggregate together in the asphalt mixture can break down, leading to cracking. Lack of regular maintenance, such as sealcoating and crack sealing, can accelerate this deterioration process. It is crucial to implement a proper maintenance plan to protect the asphalt and extend its lifespan.

Tree Roots

Trees near asphalt surfaces can also contribute to the formation of cracks. As the trees grow, their roots can exert pressure on the pavement, causing it to crack and break. Additionally, the roots can also absorb moisture from the soil beneath the asphalt, further contributing to its deterioration. Careful consideration should be given to tree placement in relation to asphalt surfaces.

Chemical Spills and Oil Leaks

Chemical spills and oil leaks are not only harmful to the environment but can also damage asphalt surfaces. These substances can penetrate the asphalt and break down the binder, leading to cracks and deteriorated pavement. Regularly cleaning up spills and addressing oil leaks is essential to prevent damage to the asphalt.
