Rosco Maximizer 2B Asphalt Distributor
Specifications
Circulating System
The circulating system has an engine driven hydraulic
pump which drives the hydraulic motor. The hydraulic
motor powers the asphalt pump allowing the pump to:
• Fill the distributor tank
• Circulate material through the bar and tank
• Spray material through the bar or hand spray
• Draw material back to the tank from the bar or hand
spray
• Pump material from the tank to outside storage
• Transfer material from one storage tank to another
The spraybar must have a constant and uniform
pressure along the entire length of the bar for uniform
output at each nozzle .
The Rosco Maximizer 2B Asphalt Distributor delivers a
volume of asphalt to the spraybar which is regulated by
a number of variables, including:
• Asphalt pump speed
• Application rate setting
• Truck speed
•
Spraybar width
The on-board computer senses the different values and
controls the asphalt pump speed to deliver the precise
amount of asphalt to the spraybar .
Both the application rate and spray pattern are
influenced by factors such as the selected application
rate, the truck speed and nozzle size .
If the nozzles are too small for the application rate and
truck speed, the liquid will atomize, the spray pattern
will distort and the result will be excessive over-spray
or inconsistent application rate . If the nozzles are
too large, the result will be streaking caused by low
spraybar pressure (see
Valves And Nozzles in Section
6) .
General Information
The descriptions and specifications provided in this
section are applicable to the Rosco Maximizer 2B
Asphalt Distributor .
This section contains a description of how the major
components operate. It also includes specifications for
the major system components. Included in this section
are machine weights, dimensions, performance, and
major system specifications for the machine.
General
The Rosco Maximizer 2B Asphalt Distributor is used
for the transportation and distribution of asphalt-based
products for road maintenance and repair. The machine
can spray asphalt emulsions, asphalt cements and
cutback asphalts . LeeBoy strongly recommends the
use of asphalt emulsions . Water based emulsions
reduce the risk of fire and explosion.
The Maximizer 2B should not be used
to distribute water, calcium chloride or other de-
icing liquids. These materials can corrode the pump
and valves and dangerously contaminate the tank.
If these materials are used in a Maximizer 2B, the
warranty is voided on those components affected by
the material.
System Overview
The Maximizer 2B consists of a truck-mounted insulated
tank ranging in capacity from 1,000 to 4,000 gal . (3,785
to 15,142 liters). ROSCO Distributors are equipped with
a heating system that will maintain the asphalt at the
proper spray temperature .
The Distributor has a power driven asphalt pump
capable of handling products ranging from light
applications of emulsified asphalt to heavy asphalt
cements heated to spraying viscosity . At the back of
the tank is a system of spraybars with nozzles through
which asphalt is forced under pressure and applied to
the road surface. The spraybars cover widths ranging
from 4 in . to 24 ft . (10 cm to 7 .32 m) in one pass .
The circulating system and the burner system are
the main systems on the Maximizer 2B . Read these
sections so you are aware of the functions and
capabilities of the unit and its systems .
