What is the acceptable temperature variation for single asphalt trucks during temping?

The acceptable temperature variation for single asphalt trucks during temping is set at ±25°. This parameter is critical because maintaining the right temperature for asphalt is essential for optimal performance and application. When asphalt is heated to a specific range, it achieves the right viscosity, allowing it to be properly mixed, compacted, and bonded.

A variation of ±25° ensures that the asphalt can still perform effectively without compromising its properties. If temperatures deviate too far from this range, the asphalt may become either too stiff to work with or too fluid, which can affect its ability to adhere to surfaces or retain strength once laid.

Understanding and adhering to this temperature variation helps ensure high-quality asphalt construction that meets industry standards and reduces the risk of issues such as inadequate bonding or premature pavement failure.
