Where should a thermometer be placed in a truck for accurate measurement?

The thermometer should be placed in the middle third of the body length of the truck to ensure accurate temperature measurement of the asphalt. This location provides a more representative sample of the overall temperature of the material being transported. Asphalt tends to heat unevenly, and placing the thermometer in the middle ensures that it is not affected by environmental factors such as wind or direct sunlight, which can influence the reading if the thermometer is located near the edges or at the bottom of the bed. By measuring in the middle third, the operator can better assess the temperature of the asphalt, which is crucial for determining whether it is within the suitable range for effective paving.
