Intelligent Asphalt Distributor is used for spraying rubber asphalt, hot asphalt, emulsified asphalt, modified asphalt.

Ⅰ,Overview

This machine was developed by Xi’an Dagang Road Machinery in 2001 and has got many mandatory tests since June 2002, acquiring the approval of The People's Republic of Economic and Trade Commission and passing the national CCC authentication. In October 2004, it got the scientific and technological achievement identification of Shaanxi Science and Technology Bureau, with the assessment: the performance of complete machine can reach the international advanced level. It was listed as National Torch Plan in September 2006. The intelligent asphalt distributor produced by Dagang Company has served the high-level road construction and maintenance project and is exported to the world since October 2004.

 

Our Intellectualized Asphalt Distributor is used for spraying asphalt on the prime coat, the water-proof layer and tack coat in high-graded road construction. It also can be used for bituminous pavement with the construction techniques of spreading in layers. It can spray hot asphalt, emulsified asphalt, modified asphalt, etc. It is mainly composed of Truck Chassis, Asphalt Tank, Asphalt Pumping and Spraying System, Heating System, Hydraulic Circuit, Pneumatic Circuit, Auto control System and Operation Panel

Ⅱ,Features

1,   Main Performance

Main performances include:

a)    All operations can be performed in the cab.

b)    Asphalt spraying rate kg/m2: 0.3-3

c)    The width of spraying is adjustable. Each spraying nozzle can be controlled independently, and the maximum spraying width can reach 6 meters.

d)    Spraying of asphalt is very even, and can realize to spray in three-overlapping.

e)    Asphalt application rate is controlled by computer and independent of truck speed.

f)    Heating and heat-preserving systems introduce full circulation of hot oil, which is safe, reliable and full-automatic.

g)    Thermal oilpreserves heat of asphalt pump and spraying nozzles, which needn’t be washed by diesel oil after finishing spraying. It uses high-pressure air to drain the pipe and spraying nozzle or make use of hot oil’s cycle to ensure pipelines and spraying nozzles not to be blocked.

h)    Control System adopts modular design, which is very convenient to maintain and troubleshooting.

i)     It is equipped with standby control system.

j)     It can ensure machine to work normally when Main Control System failure.

k)    It is equipped with flexible hand-spraying system.

l)     Excellent heat-preservation and the average temp. Fall is less than 1 °C/h.

m)   Loading and unloading asphalt is very convenient. Besides filling asphalt through manhole, asphalt can also be sucked into tank and drained by own pump.

n)    See the table for the parameter
