Specications
General Information
The descriptions and specications provided in this
section are applicable to the Rosco Maximizer 3B
Asphalt Distributor.
This section contains a description of how the major
components operate. It also includes specications for
the major system components. Included in this section
are machine weights, dimensions, performance, and
major system specications for the machine.
General
The Rosco Maximizer 3B 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 re and explosion.
The Maximizer 3B should not be used
to distribute water, calcium chloride or other deicing liquids. These materials can corrode the pump
and valves and dangerously contaminate the tank.
If these materials are used in a Maximizer 3B, the
warranty is voided on those components affected by
the material.
System Overview
The Maximizer 3B 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 emulsied 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 20 ft. (10 cm to 6.1 m) in one pass.
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:
• ll 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 3B 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
inuenced 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).
The circulating system and the burner system are
the main systems on the Maximizer 3B. Read these
sections so you are aware of the functions and
capabilities of the unit and its systems.

Rosco Maximizer 3B Asphalt Distributor
Specications
Burner System
USE BURNERS PROPERLY! Burners are used to
increase the temperature of liquid asphalt material to
the correct spraying temperatures. The burners should
only be used while the liquid asphalt material is being
circulated in the tank.
If the material has cooled to the point
that it will not ow easily and will not circulate, the
operator must use extra care. Improper heating will
cause damage to the equipment and the material
being heated.
The burners in the Maximizer 3B have a very high
heat output which must be dissipated through the
asphalt. Asphalt is an excellent insulator and resists the
conduction of heat through the material.
If the material is heated too hot or too quickly without
the proper circulation, hot spots will be created near the
rear of the tank at the ue tubes. This will damage the
ue tubes and cause a break down of the material.
Operating the burners without
circulating the product can create explosive fumes.
If the product can not be circulated after 15 minutes
of heating, the fuel to the burners must be turned off,
while leaving the blowers running. Do not try to heat
material again for 30 minutes.
If it is necessary to heat asphalt that has cooled more
than 20 to 30 degrees below the optimum spraying
temperature, the operator must use extreme care in
reheating the material.
Run the burners for short periods of
time (15 minutes ON, 15 minutes OFF) to allow the
heat to dissipate through the material. This will
prevent damage to the ue liner.
The amount of time necessary to heat the asphalt
material to allow proper circulation and heating will
vary depending on the type of material, the type of
burners, the tank size and the amount of material in the
tank. If you have any doubts about the proper way to
heat cooled asphalt, contact your asphalt supplier or
equipment manufacturer.
The Burners are located at the left rear of the Maximizer
3B. The ame from the burner is directed through
the re tubes along the bottom of the tank. Diesel or
propane can be used as fuel, depending on the burner
option specied.
Never operate the burners without rst reviewing the
instructions.
Plus One Controller
The Plus One system is used to automatically control
the application rate of the asphalt distributor truck. It is
capable of automatically maintaining constant asphalt
application rates regardless of changes in distributor
speed and spraybar width. The controller has on/off
toggle switches to provide spray nozzle control along
the spraybar in 1 foot (.3 m) increments.
Distributor functions are set by selecting one of eight
modes of operation. Each mode of operation denes
the behavior of the automatic asphalt valves and the
spraybar valves for the distributor function selected. A
software memory feature is included to store up to 12
user dened presets of operating parameters for quick
setup of application rates and speed calibrations.
Selectable readouts on the in-cab control panel display
the following in real time; distributor ground speed (fpm),
asphalt spray rate (gpm), total distance sprayed (ft), total
gallons sprayed (gal), total area sprayed (sq.yd.), ow
& speed calibration application rate (gal/sq.yd.), tank
temperature (degree F), hour meter (hr), and spraybar
length (ft).
The controller uses either a GPS Speed Sensor or
an (optional) Radar Horn Speed Sensor to measure
distributor ground speed necessary for application rate
calculations and real time display of distributor metrics.
Rear controls are located in the tool box on the right
hand side rear fender and are used to control asphalt
pump speed, asphalt pump direction, spraybar hydraulic
functions and the optional washdown pump when rear
control priority is selected.
In-Cab Operator System
The main console located in the truck cab contains a
DP610 color display and utilizes a toggle switch system
for Maximizer 3B spraybar control. Truck control
parameters and modes of operation are selected
through the DP610 display using programmable soft
keys. Setup functions and real time monitoring functions
are stored and processed in the DP610.
In addition, the console includes a Master Power ON/
OFF toggle switch, Burner switch, and potentiometer for
the control of asphalt pump speed and direction when
in MANUAL mode and front control priority. Parameters
are used to congure options installed on specic trucks
as well as increase memory and data storage capacity.
A CAN signal allows communication between the In-Cab
Controller and the control modules located in the valve
box at the rear of the truck.

Material Considerations
NOTE: All information in the Material Considerations
section was obtained from publications of the
Asphalt Institute.
This section will help the operator better understand the
properties of the asphalt product being used (see Table
4-4. Guideline Temperatures For Liquid Asphalts).
The selection of the right product is generally
dependent on the following considerations:
1. Availability of various types of aggregate.
2. Availability of various liquid asphalt grades.
3. Climate conditions during applications.
4. Trafc conditions during application.
5. Contract specications.
NOTE: The information given in the charts in this section
is based on industry standards. It is important to
note that some asphalt product manufacturers
have grades or mixtures which do not conform
to industry standards. These materials are often
tailored to local conditions and may provide
superior performance to standard grades.
There are many types and grades of asphalt products.
The best results can be obtained through the trial of
several different types of asphalt and aggregates. The
following classications and grades of asphalts are
provided to help in the selection.
Asphalt Cement (AC):
Cutback Asphalt:
• An asphalt cement which has been liqueed by
blending with petroleum solvents. Upon exposure to
the air, the solvents evaporate, leaving the asphalt
cement to perform its function of cementing and
waterproong.
When using cutback asphalts, extreme
caution must be used to prevent re or explosion. Do
not use open ames or sparks near these materials.
Use controlled heat only. Never use open ames to
examine tanks in which these materials have been
used or stored. Be sure all vehicles transporting
these materials are properly vented. Allow only
experienced personnel to handle these materials.
Be sure all applicable interstate and intrastate
commerce requirements are met.
Cutback asphalts are divided into three main grades.
1. Rapid Curing (RC) Asphalt: A cutback asphalt of
high volatility composed of asphalt cement using
naphtha or gasoline-type dilutant.
2. Medium Curing (MC) Asphalt: Cutback asphalt of
medium volatility composed of asphalt cement and
kerosene-type dilutant.
3. Slow Curing (SC) Asphalt: A cutback asphalt of low
volatility composed of asphalt cement and oils.
It is important to remember that
cutback asphalts are often used at temperatures
above their ash points. Serious injury can occur
from burns.
• Asphalt that is rened to meet specications for
paving, industrial, and special purposes.

Specications
Emulsified Asphalt:
• An emulsion of asphalt cement and water with a small
amount of an emulsifying agent. The emulsifying agent
determines the charge of the asphalt particles. It may
have a negative (-) charge called anionic, or a positive
(+) charge called cationic.
NOTE: An anionic type of emulsion will work best with
aggregates having positive (+) surface charges
such as limestone and dolomite.
A cationic type of emulsion will work best with
aggregates having negative (-) surface charges
such as siliceous or granitic aggregates.
DO NOT mix emulsion types,
especially anionic with cationic.
Standard grades of Emulsied Asphalt are:
Anionic (- charge):
• RS-1, RS-2, MS-1, MS-2, MS-2h, HFMS-1, HFMS-2,
HFMS-2h, HFMS-2s, SS-1, SS-1h.
Cationic (+ charge):
• CRS-1, CRS-2, CMS-2, CMS-2h, CSS-1, CSS-1h.
• RS, MS, SS: Indicate the emulsion setting rate. (Rapid
Set, Medium Set, Slow Set)
• h, s: Indicate if a hard or soft base asphalt is used in
the mix.
Contamination
It is very important to remember that when you are
loading a new material into the Maximizer, you must
be sure that the new material is compatible with the
residual material in the tank. The safest thing to do is
to completely clean out the tank and the entire system.
Total clean out is essential if you are not sure of the last
material that was used in the unit.
However, some materials can be loaded with a small
residual amount (0.5 % of capacity or less) of the
previous material remaining in the tank, (see Guide For
Loading Asphalt Products in Section 4).
To reduce the risks of re or explosion, follow Table
4-5. Guide For Loading Asphalt Products to eliminate
contamination.
When incompatible materials are mixed, it can increase
the possibility that the material will not meet the job
specications. More importantly, mixing materials can
increase the risk of re or explosion. For example, light
hydrocarbons may be present in a tank from previous
loads or from diesel oil or solvents used in cleaning the
tank.
Be sure the tank has no water in it
before loading. Hot material will turn water into
steam and can cause an explosion.

• HF: Indicates High-Float which means chemicals have
been added to permit a thicker lm of asphalt on the
aggregate particles to prevent drain off of asphalt
from the aggregate.
• C: Indicates a cationic asphalt. The absence of the
letter “C” means it is anionic asphalt.
Viscosity
Viscosity is a uid’s resistance to ow (how thick and
gluey a uid is). The recommended viscosity for spraying
with a distributor is 25 to 50 Saybolt Furol seconds (45 -
100 Centistokes Kinematic Viscosity).
The recommended viscosity for loading or pumping
is a maximum of 400 Saybolt Furol seconds (800
Centistokes Kinematic Viscosity).
Viscosities above these ranges will limit the
performance of the machine. Your asphalt provider will
be able to tell you the viscosity of your product.
