Where should the hole be located for temping asphalt trucks?

The optimal location for holes used to temper asphalt trucks is on both sides of the truck, positioned 6-10 inches higher than the bottom of the bed. This configuration facilitates a balanced and effective discharge of the asphalt material. By having holes on both sides, it ensures that the material can flow freely and reduces the likelihood of having a buildup of asphalt, which can cause overheating or uneven temperature distribution within the truck bed during transport.

Positioning the holes higher than the bottom of the bed allows for better air circulation and helps maintain the temperature of the asphalt as it is being dispensed. This is crucial because maintaining the right temperature is key to ensuring proper compaction and performance after the asphalt is laid.

The other options do not provide the necessary considerations for effective asphalt flow and temperature control. Relying on a single side would limit accessibility and could lead to uneven material flow or difficulty in completely emptying the truck. Placing the hole near the front or the back of the truck does not account for the need for symmetry and balance in the material discharge process. Thus, the choice of having the holes on both sides at the specified height promotes efficiency and effectiveness in asphalt handling.
