Causes of Asphalt Cracks 1

Lack of Maintenance

One of the main causes of asphalt cracks is a lack of maintenance. Over time, asphalt surfaces can become worn and damaged due to exposure to the elements, such as UV rays from the sun, rain, and extreme temperatures. If cracks are not repaired in a timely manner, they can widen and deepen, leading to more extensive damage to the asphalt.

Heavy Traffic

Another factor that contributes to asphalt cracking is heavy traffic. Constant weight and pressure from vehicles passing over the surface can cause the asphalt to weaken and crack. This is especially true for roads and parking lots that experience high volumes of traffic on a daily basis. The repetitive stress on the asphalt can eventually lead to the formation of cracks.

Freeze-Thaw Cycles

Freeze-thaw cycles can also cause asphalt to crack. When water seeps into the cracks or pores of the surface, it can freeze during cold temperatures, causing it to expand. As the ice expands, it puts pressure on the surrounding asphalt, leading to cracking. When the ice melts, the asphalt contracts, creating further stress on the surface and exacerbating existing cracks.

Poor Installation

Inadequate installation techniques can contribute to the development of cracks in asphalt surfaces. If the asphalt is not properly compacted during installation, it can lead to weak spots and uneven surfaces. These weak areas are more prone to cracking, especially under the weight of vehicles or exposure to environmental stressors. Additionally, improper mixing of the asphalt can result in a weaker surface that is more susceptible to cracking.

Chemical Damage

Chemical damage is another cause of asphalt cracks. Chemicals such as gasoline, oil, and de-icing salts can deteriorate the asphalt surface, making it more vulnerable to cracking. Gasoline and oil can penetrate the asphalt and weaken its structure, while de-icing salts can chemically react with the asphalt, accelerating its deterioration process. Regular cleaning and sealing can help protect the asphalt from chemical damage.


Understanding the causes of asphalt cracks is important in order to prevent and address them effectively. Regular maintenance, including crack sealing and proper surface preparation, can help prolong the lifespan of asphalt surfaces and minimize the occurrence of cracks. Additionally, proper installation techniques and protection from heavy traffic and chemical damage are crucial considerations for preventing asphalt cracks. By being proactive in maintaining and protecting asphalt surfaces, we can ensure their durability and longevity. Utilize this external content to explore the subject further.
