How Does Rain Affect Asphalt Paving Jobs?

When you're in the middle of an ongoing asphalt paving project, staying on schedule is extremely important. But what happens when you experience unexpected rain showers in the middle of the construction?

The weather patterns in the southeastern United States can be unpredictable, which is why you need to be working with asphalt paving contractors who know how to work their way around rain and other inclement weather in this part of the country.

Why You Cannot Pave Asphalt in the Rain

Paving asphalt in the rain cannot be done because of the nature of the asphalt mix. Asphalt contains petroleum, which behaves like oil, and oil and water simply don’t mix. When asphalt is applied on a wet surface, the oil within the mix rises to the top, affecting the curing time and the quality of the finished product. It will also cause delays that can throw off the entire project timeline. The stability of the subsoil will also be compromised when it comes into contact with rainwater, creating a soft and unstable foundation.

Another factor to consider is that high temperatures are required for asphalt paving.  The rain will cool down the asphalt mix too quickly, which could impact the paving process. Additionally, rainwater can become trapped between the layers of asphalt, leading to structural issues down the line. This trapped water can weaken the integrity of the newly paved surface, resulting in premature deterioration and the need for costly repairs.

Attempting to pave asphalt in the rain is a recipe for disaster that can compromise the integrity and longevity of your pavement. That’s why it’s essential to schedule paving projects during periods of dry weather whenever possible, and to partner with the right asphalt company who can make adjustments during less-than-ideal weather conditions.

How Contractors Safeguard the Asphalt Pavement Against Rain

When rain threatens to disrupt an ongoing asphalt paving project, experienced crews employ a variety of strategies to safeguard the pavement from damage. These measures help to ensure that the finished surface meets the highest standards of quality even in the face of unpredictable weather conditions. One effective approach is the use of temporary protective coverings, such as tarps or plastic sheeting, to shield freshly laid asphalt from rainwater.

Additionally, crews may also roll or compact the asphalt mix more aggressively to squeeze out excess moisture and ensure that the pavement sets properly. Closely monitoring weather forecasts and planning paving activities around periods of dry weather allows contractors to minimize the likelihood of rain-related delays and interruptions.


By partnering with an experienced asphalt paving company like Wright Construction, you can ensure that your paving project stays on track and yields a high-quality, long-lasting result. So, the next time rain threatens to put a damper on your asphalt paving plans, you can have peace of mind knowing that your project is in good hands.
