CONCEPT
The transfer of energy from the storage bin walls to the material and
throughout is by conduction.
Asphalt can be maintained as workable material for lengthy time periods
and/or it can be recycled from a hardened state to a malleable product
when kept at a specified temperature.
The physical properties of the material will vary due to manufacturing and
aging.
A note of caution; over-heating or heating asphalt for extended periods of
time will cause oxidation of the material and irreversible hardening.
NOTE: Plant mix design now incorporates more recycled rap! The mix
must be evaluated on every load for AC richness to ensure your success in
RECLAIMING.
The unit also offers the ability to safely maintain temperatures that
accommodate standard “cold patching” materials.
The heating unit is an efficient use of fuel and controlled by thermostat.
The temperatures can be effectively monitored by thermostat and can be
set to heat from ambient ranges up to a maximum of 350 degrees
Fahrenheit (350
o
F).
An optional low temperature thermostat is recommended to accommodate
the range suggested for cold patching materials, which is approximately 80
degrees Fahrenheit (80 F).
ASPHALT
STORAGE BIN
The asphalt storage bin will hold a capacity of four (4) tons of material.
The storage bin measures 64” x 72” x 56” from base of bin to peak.
The design offers gravity feed of the material towards the shovel ports.
The asphalt bin is constructed of four (4) 12 gauge welded steel walls.
The floor will be constructed of one solid piece of 12 gauge steel.
A third wall of reflective aluminum is attached and located between the
storage bin and the outer shell.
2,300 degree Fahrenheit refractory ceramic insulation located between the
reflective wall and bottom floor insulates the bottom of the unit.
High temperature fiber glass insulation not less than 2” in thickness
insulates the exterior walls of the unit.
The outer shell will be fabricated of braced 16 gauge steel.
All seams will be a continuous weld.
Interior gussets and supports welded at strategic points provide additional
fabricating rigidity.
The rear panel of the bin provides two (2) 16” x 20” shovel ports.
The heat source is a 60,000 BTU liquid propane gas vapor burner.
Temperature is monitored by a thermostat.
The thermostat controls the temperature settings from 175 to 350 degrees
Fahrenheit.
