Abstract: Being the main road surface material, asphalt require to be heated during its production,store and utilization. It has been devoloping a new technology to heat asphalt by heavy burning oil. This method require less equipments to produce high thermal efficiency, and it can save energy, and reduce enviromental pollution. The paper will discuss the technology of heating asphalt by heavy burning oil, focusing on its heating mechanism, processing and the factors to be attention.

Key words: heavy burning oil, asphalt, fire pipe, oil fog
