Where should the hole for temping asphalt trucks be located?

Locating the hole for temping asphalt trucks in the middle third of the length of the truck is essential for accurately measuring the temperature of the material being transported. This position is optimal because it is likely to provide a more uniform temperature reading, as it is away from the influences of heat loss at the front and rear of the truck, which can occur due to exposure to air and other environmental factors.

The middle third of the truck also represents a point where the asphalt has likely retained heat more effectively, ensuring that the temperature measurements reflect the overall condition of the load rather than localized hot or cold spots. This practice helps in complying with quality control standards for asphalt paving, as temperature significantly affects the material's workability and performance.
