How does temperature affect asphalt paving?

Temperature plays a crucial role in the processes of asphalt paving, particularly impacting workability and setting time. When asphalt is heated, it becomes more workable, allowing for easier manipulation and placement during the paving operation. The warmer the asphalt, the more fluid it is, which facilitates the application and compaction. Conversely, cooler temperatures can cause the asphalt to stiffen, making it more difficult to handle and properly compact.

Additionally, the setting time of asphalt is significantly affected by temperature. Higher temperatures generally reduce the setting time, allowing the asphalt to be trafficked more quickly after placement, whereas lower temperatures can prolong the curing process, leading to potential quality issues. As such, understanding and managing the temperature of asphalt during paving is essential to ensuring a high-quality finish and long-lasting pavement. This highlights the importance of temperature control in asphalt paving operations.
