Asphalt spreading truck is a kind of black road construction machinery and is the main equipment in the construction of highways, urban roads, airports and port terminals. When constructing asphalt pavement or maintaining asphalt or residual oil pavement using asphalt penetration method and asphalt layer surface treatment method, asphalt spreader trucks can be used to transport and spread liquid asphalt (including hot asphalt, emulsified asphalt and residual oil).

In addition, it can also supply asphalt binder to the loose soil in place for the construction of asphalt stabilized soil pavement or pavement base. When constructing the permeable layer, waterproof layer and bonding layer of the bottom layer of high-grade highway asphalt pavement, high viscosity modified asphalt, heavy traffic asphalt, modified emulsified asphalt, emulsified asphalt, etc. can be spread. It can also be used for asphalt covering and spraying in highway maintenance, as well as for the construction of county and township-level highways that implement layered paving technology. The intelligent asphalt spreader truck consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.

Classification of asphalt spreading trucks:
1. Classified according to usage, operation mode and driving mode of asphalt pump.
2. According to their uses, asphalt spreading trucks can be divided into two types: road construction and road construction. The asphalt tank capacity of the asphalt spreader used in road construction projects generally does not exceed 400L, while in road construction projects its tank capacity is 3000-20000L.
3. According to the driving mode of the asphalt pump, it is divided into two modes: the asphalt pump is driven by the automobile engine and the asphalt pump is driven by another engine set separately. The latter can adjust the amount of asphalt spread within a wide range. The asphalt spreading trucks produced in my country are all self-propelled asphalt spreading trucks without special engines, except for the simple towed ones made by each user department.
