On the basis of introduced advanced technologies both domestic and abroad, this easy-operated distributor adds some humanized designs that ensure technical content of construction quality and improve construction conditions and environment. Its reasonable designs guarantee the asphalt spray uniformity. Industrial computer control is stable and reliable. The technical performance of overall machine has attained the advanced world level. This distributor has been improved and perfected in the construction by our construction department, which adapts to any kind of working conditions.
Operation 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.
Construction technology introduction
Asphalt distributing is used special asphalt distributor to spray hot asphalt on pavement on the basis of measured distributing amount and pressure. It is mainly used deal with the construction of upper and lower seal coat, prime layer, asphalt surfacing, asphalt penetration surface, fog seal layer and so on.

||
asbestos insulation layer with thickness of 100mm preserves heat of heated asphalt. Good anticorrosion and durable insulation layer maintain temperature drop by no more than 12℃/8h |
||
Stainless steel frosted board out of the insulation layer is elegant and easy to clean. |
||
There is a device to indicate asphalt level and a limiting switch to control asphalt safe level. Both of them can avoid the dangerous from the more or less amount of asphalt. |
||
It can self-priming and discharge, which can add or discharge the asphalt automatically, increase the efficiency |
||
6 |
Spray System |
Asphalt pump: It adopts JOHNSON asphalt pump，which has good pumping capacity， large discharge capacity，can do a better performance of asphalt circulation and spraying. |
Asphalt Pipeline can realize the HTF whole coverage，guarantee the smooth circulation of asphalt in the pipeline. |
||
Special folding Spray Bar are used,proper asphalt circulation and precise nozzle design ensure the accuracy and uniformity distributing precision |
||
It can spray all kinds of asphalt,especially hot (modified) asphalt, asphalt rubber. |
||
Spray volume：0.2-3kg/m2，48 nozzles in all.Each has the space of 125mm |
||
Each nozzle can be controlled by computer.Precise spraying and aren't influenced by speed. |
||
Computer control the whole process of spraying，it can change the spraying width any time to meet the need of different pavement. |
||
7 |
Heating |
Italy RIELLO diesel burner is applied.The Calorific value：20×104kcal/h） |
U-shape heating tube make the system heat fast. |
||
The HTF coil are parallel double loop,make the heat speed fast. |
||
The HTF make the asphalt cover all the pipe,which can realize no-clean |
||
The upper and lower limits can be set,which are more safe and reliable. |
||
8 |
Air circuit system |
Plenty air source directly from the chassis guarantees the good performance of asphalt spray, spray bar lift and swing, air control angle seated valve and water system. |
Long-life service solenoid directional valve and elements are used |
||
Main vehicle air source and each air source are control by different pressure regulator and ball valve separately, which can ensure the main vehicle air source and make each air source without interference at the same time. |
||
9 |
Water circuit system |
The water nozzle are installed on the upper part of each tire, which can effectively prevent asphalt adhesion on the tires during the construction process, avoid tire skidding on the mountain road and reduce tire temperature of long distance travel in summer. |
The main vehicle air circuit give the pressure to the water tank,Simple and convenient. |
||
10 |
Power Supply System |
The engine PTO give the power to whole equipment. |
The power is taken by stable and credible transfer case. |
||
11 |
Electrical system |
Asphalt spray can be controlled in the cabin with operation buttons |
It adopts domestic and international famous components, which efficiently improved the stability of electrical system. This controller has characteristics of high grade of protection, dust proof, water proof and quake proof. |
||
Work according to the different requirements for operators to provide accurate distributing parameters, through the cabin or the back platform, the actual measurement parameters changing accurately reflects the operation of the equipment |
||
PLC can modify parameters based on the actual asphalt density and load amount to accurately control the output of asphalt pump to keep spray precision error of ±1%. |
||
It adopts the encode to accurately detect the asphalt pump speed. |
||
Simple Manual operation.Easy switch between manual and automatic mode. |
||
It uses imported american radar detector, which has advantages of high accuracy, large speed measure scope, easy operation and good adaption. |
||
Distribution box design with high protection against corrupt design, reduce the power distribution box components by tar and dust pollution |
||
