What is the recommended procedure for heating asphalt bitumen?

The recommended procedure for heating asphalt bitumen involves circulating and stirring it during the heating process. This method ensures that the bitumen heats evenly and prevents localized overheating, which can lead to degradation of the material. Stirring promotes uniform temperature distribution, ensuring that the bitumen reaches the desired viscosity for optimal application.

Heating asphalt in this way also allows for better control over the process, reducing the risk of combustion or excessive fuming, which can occur if the bitumen is heated too quickly or unevenly. Overall, this practice helps maintain the integrity of the asphalt and leads to a more effective application.
