When planning a commercial paving project, ensuring ideal conditions while the asphalt is drying is necessary for its strength and long-term durability. Timing is a major concern in all projects, whether you’re updating a parking lot or constructing a new industrial yard.
Understanding the drying process minimizes business disruptions and maximizes the asphalt surface’s lifespan. Discover what the asphalt curing process involves and what to expect when partnering with a commercial asphalt paving company.
What Is the Drying Process for Commercial Asphalt?
A professional asphalt paving company typically splits the drying process into two stages: the initial curing, during which the asphalt mixture hardens, and full curing. Here are the main differences between the two:
- Initial drying. During this part of the process, the freshly poured asphalt layer cools and hardens, becoming durable enough for light foot traffic or vehicle movement. For most projects, this takes 24 to 48 hours.
- Full curing. Once the asphalt has finished hardening, it needs approximately 6 to 12 months to fully cure. The material continues to settle and harden during this time, achieving maximum durability.
Factors That Affect Asphalt Drying Time
The time it takes for the drying and curing process to complete varies depending on many factors. An experienced asphalt construction partner provides expert advice and accurate project timelines. Below are the main factors that can affect your asphalt project’s drying and curing times:
Weather Conditions
The weather affects asphalt drying time. Warm, dry climates are ideal for speeding up the process. Colder or rainy regions need extra drying and curing time to ensure durability.
Areas such as Charleston, SC, are frequently exposed to high humidity levels and exposure to sea air. They require the expertise of a local commercial asphalt paving company with experience completing asphalt projects in the region.
Thickness of the Asphalt Layer
The thicker an asphalt layer is, the longer it takes to cool, harden, and cure properly. This is because thick asphalt mixes retain heat for longer periods. For instance, a typical 3-inch lift takes four times as long to cool and dry as a 1.5-inch lift under the same weather and climate conditions.
An asphalt specialist will recommend the right layer thickness for durability while keeping your project on schedule.
Type of Asphalt Mix
Asphalt mixes vary; some dry quickly, while others focus on long-term durability. Generally speaking, the hotter the mix temperature, the longer it needs to dry due to heat retention. However, lower-temperature mixes may not be as durable; some, such as Cold Mix Asphalt (CMA), are only suitable for repairs or pothole fixing. Leave the asphalt mix choices to the experts; they will help you find the right one for your project’s needs.
Tips for Proper Asphalt Care During the Drying and Curing Process
Proper care during drying and curing is crucial for a lasting surface. Here are some best practices:
- Limit heavy traffic. Avoid allowing large vehicles on the asphalt surface until it has fully cured. Letting heavy vehicles onto asphalt that hasn’t fully cured can cause it to crack or deform under the weight.
- Monitor weather forecasts. Plan your paving project for warm, dry stretches like late spring or early summer in South Carolina. Ideal conditions include dry, warm temperatures both before and during the pour and while the surface sets and hardens. Once the asphalt has fully set, it can begin curing and will be durable enough to handle rain and other inclement weather.
- Sealcoat after curing. Sealcoating is a protective measure that can extend the life of your asphalt. An asphalt company will typically recommend applying sealcoating once the asphalt has finished curing.
- Regular sealcoating reapplications. While it can seem like an additional expense, sealcoating after curing and once every 2 to 3 years protects the surface and increases its resistance to water, oil, chemicals, and UV rays. It can extend the asphalt’s lifespan by up to 20 years, making it a worthwhile investment.
Why Partner with a Commercial Asphalt Expert?
