Road construction machinery is a high-cost operation. Its structural nature determines that high-cost maintenance is required in terms of procurement, leasing, maintenance, accessories, and fuel consumption. For Duyu users, effective control of operating costs is a top priority for their interests. Especially at a time when work is not doing well, cost savings are even more critical. So, how to control capital well?

The inspection and management of road construction machinery is of great significance in actual work. It includes three major aspects, namely equipment inspection, equipment use management and the establishment of a preventive maintenance system.

In production, we often cannot do without the help of mechanical equipment. A good piece of equipment can help us complete our work better. However, when using equipment, we should use and operate it correctly in accordance with regulations. According to research, the correct use of road construction machinery is an effective way to increase equipment utilization. Not only that, but it can also maximize the potential of the equipment.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

The thermal oil asphalt tank is equipped with heating pipes. Pour high-temperature heat transfer oil into the heating coil. Under the action of the hot oil pump, the heat transfer oil is forced to circulate in a closed circuit within the heat transfer oil pipeline system. The heat transfer oil carrying high temperature is transported to the thermal equipment, and the heat energy is transferred to the low-temperature asphalt, thereby increasing the temperature of the asphalt. After heat dissipation and cooling, the heat transfer oil returns to the heating furnace for reheating and cycle heating.

In the asphalt mixing process, heating is one of the indispensable links, so the asphalt mixing station must be equipped with a heating system. However, since this system will malfunction under the influence of various factors, it is necessary to modify the heating system to solve hidden problems to reduce such situations.
First of all, let’s first understand why heating is needed, that is, what is the purpose of heating. We found that when the asphalt mixing station is operated at low temperatures, the asphalt circulation pump and spray pump cannot operate, causing the asphalt in the asphalt scale to solidify, which ultimately leads to the inability of the asphalt mixing plant to produce normally, thus affecting the Quality of construction work.
