Asphalt heater is usually called oil heating temperature controller. Its heating power is very high and the flow rate of the pump is also large. Even if the operating pressure is relatively low, the temperature of the heat transfer oil can be heated to about 345℃. It uses heavy oil, light oil, coal, etc. as fuel, and the heat transfer oil is used for heat conduction. The oil pump is used to force it to circulate, and after transferring the heat to the equipment that needs heat, it returns to continue heating, and the electric heating equipment is cyclically repeated. Asphalt heater is a popular electric heating equipment nowadays. It is safe and efficient, environmentally friendly and energy-saving. It meets the requirements of high-precision temperature control and heating process and adapts to the needs of development.

Colored anti-skid pavement achieves its anti-skid effect through the following three aspects: (1) The surface structure depth of ordinary pavement is greatly increased by paving colored anti-skid pavement, which increases the anti-skid performance of the pavement. Experiments show that the structure depth of ordinary asphalt pavement is 0.65mm, and the BPN value is 70 in a wet state. The structure depth of the newly paved colored anti-skid pavement increases to 0.82mm, and the BPN value also increases to 85. It can be seen that the colored anti-skid pavement greatly improves the anti-skid resistance of the pavement.

Large-capacity asphalt spreaders can also be used as asphalt carriers, mainly used for asphalt penetration surface treatment, penetration layer, adhesion layer, on-site mixing of mixtures, asphalt stabilized soil and other construction and maintenance projects So how to maintain asphalt spreaders in winter?
