ASPHALT ANSWERS
While large asphalt distributor trucks are efficient for some jobs, many asphalt companies prefer a smaller unit for commercial jobs.

AC also only needs tank circulation
to keep it heated and mixed. A tank
that can spray AC most likely will also
spray emulsion if it has temperature
controls that allow it to.
Crack fillers or rubberized material
is a highly specialized product used
to fill cracks and seal joints. Most of
this material comes in solid blocks
and require heat around 400 degrees
to allow it to flow. Equipment used
for this type of material is also are very
specialized. These units will have a
double walled tank with heating oil in
the middle. Once the material is hot
enough to flow it is pumped through
or emulsion is nothing more than water and tar mixed
using a chemical called an emulsifier.
a wand and injected into the crack.
You should never put Rubberized
material through an AC or tack tank.
Neither type of unit gets hot enough
to allow material to flow.
The last of these products is driveway
sealer. Driveway sealer does not
require any heat but most products
have sand added to them for antiskid
proposes. This material requires regular
agitation and the equipment normally
has some kind of wiper paddles
to help keep the sand suspended in
the material. They normally have a diaphragm
pump versus a rotary pump.
A diaphragm pump is made to handle
the abrasiveness of sand. Of course
with no heat you would not put any
of the above material through a sealcoat
machine. Normally I get the
question can I put sealcoat material
through one of the above machines.
The answer is I would not recommend
it.
Bottom line if you have an existing
piece of equipment and want to find a
way to utilize it in other ways, it would
be best to check with the manufacturer.
