Asphalt spreaders are a type of black pavement construction machinery and are the main equipment for the construction of highways, urban roads, airports and port terminals.
When using the asphalt penetration method and asphalt layer surface treatment method to build asphalt pavements or maintain asphalt or residual oil pavements, asphalt spreaders 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 on site for the construction of asphalt stabilized soil pavements or pavement bases.
When constructing the permeable layer, waterproof layer and bonding layer of the bottom layer of the asphalt pavement of high-grade highways, 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 highway oil roads using layered paving technology.
The intelligent asphalt distributor 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 distributors:
Asphalt distributors are classified according to their purpose, operation mode, and the driving mode of the asphalt pump.
According to their purpose, asphalt distributors can be divided into two types: road repair and road construction.
The asphalt tank capacity of the asphalt distributor used in road repair projects generally does not exceed 400L, while the tank capacity in road construction projects is 3000-20000L.
According to the driving mode of the asphalt pump, it is divided into two modes: the asphalt pump is driven by the car engine and the asphalt pump is driven by another engine set separately.
The latter can adjust the amount of asphalt spread within a large range.
Except for the simple towing type made by each user department, the asphalt distributors produced in my country are all self-propelled asphalt distributors without dedicated engines.
