The Dongfeng Tianjin asphalt distributor truck is equipped with computer control systems such as Siemens from Germany. The spraying amount and width can be controlled by the touch screen in the cab, and the spraying amount can also be compensated by computer speed, so that the spraying amount is not affected by changes in vehicle speed.

The Dongfeng Tianjin asphalt distributor truck is a special-purpose vehicle suitable for highway construction and maintenance operations. Common models have a capacity of 8-10 cubic meters, with some derivative versions including 6 cubic meters. Its core configuration and performance are as follows:
1. Chassis and Powertrain: Built on the Dongfeng DFL1180BX8 original chassis, the mainstream model is equipped with a Cummins 240hp National IV/National V diesel engine; matched with a Fast eight-speed gearbox, the wheelbase is mostly 3950mm, and it also features power steering, air brakes, and air conditioning. With 9.00 steel radial tires, it boasts strong driving stability and a maximum speed of 90km/h.
2. Tank and Insulation: The mainstream model has a tank capacity of 8000-10000L, with a 6 cubic meter version also available. The tank body is insulated with a 50mm rock wool layer and encased in matte stainless steel. An insulation layer separates the inner and outer tanks, providing excellent static insulation performance with an average temperature drop of ≤1-2℃/h, effectively maintaining the temperature of liquid asphalt and suitable for long-term operation.
3. Core Operating Configuration: Equipped with an Italian-imported G20 diesel burner, it automatically heats up using heat transfer oil, achieving a heating rate of 10-15℃/h. It can spray various media such as hot asphalt and modified asphalt. Standard configuration includes 36-48 individually controllable intelligent nozzles in a one-to-one control mode, with a maximum spraying width of 6 meters, a spray rate of 0.25-4.0L/㎡, and an error margin of only ±1.5%. It also supports triple-overlap spraying, allowing for hand-held spraying in corner areas.
4. Intelligent Control and Safety: Equipped with a German Siemens computer control system, the spray rate and width can be controlled via a touchscreen in the cab. Computer-aided speed compensation ensures that the spray rate is unaffected by changes in vehicle speed. After the operation, high-pressure air can be used to press the asphalt in the pipeline back into the tank and blow out the nozzles to avoid clogging. Some models are also equipped with a backup control box on the rear work platform, which can be activated to ensure operation in case of main control failure.
