What is the temperature at the surface of asphalt mentioned?

Asphalt is typically applied at elevated temperatures to ensure proper application and adherence to the substrate. The most commonly referenced temperature for the surface of asphalt during application is approximately 250°F. This temperature is optimal for facilitating the workability of the asphalt, ensuring it can be properly compacted and formed to the desired smoothness, thus providing the best performance in terms of durability and longevity of the roadway surface. Recognizing the correct temperature is critical for achieving effective bonding between layers and preventing issues such as premature cracking or raveling. Higher or lower temperatures might lead to problems in application, which is why the ideal range is often emphasized in construction practices.
