What is the proper method for stirring hot asphalt in a kettle?

The proper method for stirring hot asphalt in a kettle is to use an object that is not heat-conducting. This is important because heat-conducting materials, such as metal, can transfer heat too quickly from the asphalt, potentially leading to burns or unsafe handling. Non-heat-conducting materials, like certain plastics, can provide a safer stirring method, allowing workers to mix the asphalt effectively without the risk of handling highly heated equipment that might cause injury.

Using a metal stirring rod poses a risk of burns due to its ability to transfer heat, while a wooden paddle can splinter or break down over time when exposed to high temperatures. Power tools may not be appropriate since they could introduce additional hazards, including safety risks associated with using electrical devices around hot materials or volatile substances. By prioritizing a non-heat-conductive object for stirring, safety is maintained while ensuring the asphalt is mixed thoroughly.
