The automatic asphalt distributor is researched and developed by Sinoroader through years of construction and equipment design experience based on the present road conditions. It is one of the series of asphalt distributing machinery which is easy-operated, economical and practical. It is professional construction equipment specialized in spraying emulsified asphalt, cutback asphalt, hot asphalt, hot modified asphalt and various binder.


On the basis of introduced advanced technologies both domestic and abroad, this distributor add some humanized designs that ensure technical content of construction quality and improve construction conditions and environment. Heat oil pipe is equipped in asphalt pipelines. Heat oil internal heating method guarantees liquid running smooth and prevents asphalt from coke burning. In the process of manual spray, the rotation indicator reads asphalt pump rotation speed. The operator could calculate the corresponding vehicle speed and asphalt rotation speed to different spray volume according to our specified formula, so as to guarantee uniform spray volume. In the process of automatic spray, the operator just set spray volume in the console and start velocity meter, and then the automatic control system could regulate asphalt pump rotation speed according to the vehicle speed, so as to guarantee precise and even spray. Its reasonable designs guarantee the asphalt spray uniformity. This product gets through the strict detection of our operators and enjoys stable and reliable construction performance, and is known as ideal economical road maintenance equipment.

It could be used to deal with upper and lower seal layer, prime layer, asphalt surfacing, asphalt penetration surface, fog seal layer and so on. It also could be used to transport liquid asphalt and other heavy oil.


Components and Structures

Key components, such as auxiliary engine, hydraulic pump, hydraulic motor, asphalt pump, HTF pump, burner, air control angle seat valve, cylinder and other parts, are all international and domestic famous brands. Optimized design of each part makes sure reliable performance and prolonged the serving life. Asphalt distributor mainly contains chassis, power unit, media storage device, airflow path system, water sprinkling system, hydraulic driving system, control system, spray system, heating system and other parts.

Working principle

The operating principle of asphalt distributor is to pump the hot asphalt from asphalt storage pool into asphalt tank through asphalt pump; Transport it to construction site and heats the asphalt up to working temperature by heating system; Open asphalt pump and spraying valve by operating electrical apparatus control system; According to three overlapping spraying effect to spray the hot asphalt on pavement on the basis of measured distributing amount and pressure. The residual asphalt in pipeline will be transported into asphalt tank after finishing the work.
