How Seasonal Changes Affect Asphalt Pavement in Missouri
Understanding Seasonal Changes
Missouri experiences a diverse range of weather conditions throughout the year, from hot summers to cold winters. These seasonal changes can have a significant impact on asphalt pavement, influencing its durability and longevity. Understanding how these changes affect asphalt can help in planning maintenance and extending the life of your pavement.

Summer Heat and Asphalt
During the summer months, Missouri's temperatures can soar, reaching highs that can cause asphalt to soften. This softness can lead to rutting, where the pavement develops depressions due to the weight of vehicles. Additionally, the intense heat can cause asphalt to expand, leading to cracking and other surface issues.
To combat these effects, it's important to ensure proper compaction during the initial installation and to use high-quality materials that are designed to withstand heat. Regular inspection during the summer can help identify potential issues before they become major problems.
Winter Freezing and Thawing
In contrast to the summer, Missouri winters bring freezing temperatures that can be harsh on asphalt. Water from rain or melting snow can seep into cracks in the pavement. When temperatures drop, this water freezes and expands, causing the cracks to widen and potentially leading to potholes.

The freeze-thaw cycle is a major contributor to pavement deterioration. To mitigate this, it's crucial to seal cracks and apply a protective sealant to prevent water infiltration. Timely maintenance in the fall can prepare your asphalt for the colder months ahead.
Spring Rains and Drainage
Springtime in Missouri often brings heavy rainfall, which can contribute to issues with asphalt if proper drainage is not in place. Standing water on asphalt surfaces can exacerbate existing cracks and lead to quicker deterioration.
Ensuring that your pavement has adequate drainage solutions, such as sloping surfaces and clear gutters, is essential. Regularly checking these systems during the spring can help maintain the integrity of your asphalt.

Preventive Maintenance Tips
Regular maintenance is key to extending the life of asphalt pavement through Missouri's seasonal changes. Here are some tips:
- Sealcoating: Apply a protective layer to shield against UV rays and water infiltration.
- Crack Sealing: Repair cracks promptly to prevent them from expanding due to weather changes.
- Regular Inspections: Conduct routine checks to identify and address issues early.
Conclusion
By understanding how seasonal changes affect asphalt pavement in Missouri, property owners can take proactive steps to protect their investment. Implementing regular maintenance and using quality materials can significantly reduce the impact of weather-related wear and tear. With these strategies, you can ensure that your asphalt surfaces remain smooth and durable year-round.
