TWO-BURNER RECYCLER OPTION INSTRUCTIONS
Both RAP and stockpiled virgin hot mix asphalt that has been broken into large pieces can be
placed in the hopper, and broken down into a reusable form through a heating process. By
surrounding the material with heat, the chunks of material can be converted to a malleable form
and used to fill potholes. The time it takes to break down the material depends on 1) whether or
not the material is virgin hot mix, RAP or millings, 2) whether or not the material has been
compacted, 3) the age of the material being recycled, and 4) the ambient air temperature. It may
be better to allow the material to recycle longer at a lower temperature setting in order to preserve
the oil content of the recycled material and have a better product for making asphalt repairs.
As a general rule, it takes one to two hours to break down one ton of virgin asphalt hot mix if the
ambient temperature is 70 degrees. To effectively use people resources, the hopper can be
loaded at the end of a workday and a timer can be set to start the burner at a specific time and
break down the material overnight. The automatic temperature control feature of the machine will
keep the material at the appropriate temperature until street crews are ready to begin patching.
After the material reaches the temperature set on the controller, the burner shuts down until the
temperature of the hopper drops ten degrees at which time the burner re-ignites to heat the
material.
NOTICE: The type of asphalt being recycled has an impact on the length of time required to
recycle as well as the quality of the product once broken down. Virgin asphalt will yield the
best product and recycle the fastest. Dense, compressed asphalt will take longer to
recycle.
INSTRUCTIONS TO RECYCLE ASPHALT
1. WARNING: Recycle asphalt outdoors to prevent a buildup of diesel fumes in an
enclosed area.
2. Make sure material metering door is in the closed position.
3. Fill diesel fuel tank.
4. Open then lock loading doors in the open position per operator’s manual instructions and
load material to be recycled. Layering three or four times with a rejeuvenating liquid will
yield a better product -- especially when working with older RAP.
5. Close loading doors. (Keep loading door handles fully retracted while closing).
6. Using a heavy-duty UL approved extension cord, plug in 24-hour timer to a power source
with a 120VAC ground fault circuit interrupt. Plug into building power

7. Set temperature on controller between 260 and 340 degrees.
