Asphalt paving is a popular choice for commercial properties due to its durability, low maintenance, and aesthetic appeal. However, the weather can play a significant role in the success of an asphalt project. One common question that arises is: Can asphalt be paved in the rain? In this article, we’ll explore the risks and precautions associated with pouring asphalt in rainy conditions.
The Risks of Pouring Asphalt in the Rain
When rain comes into contact with fresh asphalt, it can cause the oil components to rise to the surface. This reaction can negatively impact the curing time and the overall quality of the finished product. Laying asphalt shortly after rainfall may lead to a variety of issues, including:
Prolonged curing time, delaying the usability of the surface
Structural damage such as pitting or cracking on the asphalt surface
Compromised integrity due to the formation of a barrier between the top layer and the base
Weakened bond between the aggregate and the binder, leading to further deterioration
Additionally, rain can jeopardize the stability of the subsoil, causing it to become soft and unstable, which is not an ideal surface for paving.
Precautions to Take Before Pouring Asphalt
To minimize the risks associated with pouring asphalt in the rain, it’s essential to take certain precautions:
Plan asphalt paving projects for clear weather conditions and ensure there are a few days of clear weather in the forecast after installation to allow for proper drying and curing.
Hire professional paving services to ensure the project is carried out efficiently and effectively.
Invest in sealcoating services a few months after the initial paving to protect the asphalt from harsh weather conditions and extend its lifespan.
If rain is unavoidable, it’s crucial to address any cracks or damage immediately to prevent further deterioration. Cleaning spills promptly and adding a waterproof sealant to the asphalt surface can also help protect the pavement during the curing process.
