Asphalt heating is an essential process in asphalt pavement construction, and asphalt heating equipment is an indispensable equipment; in this context, the small-scale drummed asphalt melting heating equipment with simple structure, economic and practical will have a good market prospect. The overall concept of the product is: 1) miniaturization, suitable for small-scale construction, each time the barrel heating
4 ~ 6 barrels of asphalt in barrels; 2) easy to move with traction; 3) simple structure and low cost; 4) ensure that the heating process will not damage the quality of asphalt.
At present, the heating methods of asphalt heating equipment used in construction including gas pipe heating, heat conducting oil heating, electric heating, steam heating, solar heating, etc.; the electric heating has high requirements for power supply, and the steam heating method is less used due to the construction site conditions; solar heating is still in the test Stage, far from the stage of practical use. Therefore, gas pipe heating and heat transfer oil heating are mainly used. These two kinds of heating equipment have their own advantages and disadvantages
