The truck-mounted M212 can
carry 12 yd3 (9.2 m3) of aggregate in a level struck
load, 691 gallons (2,616 liters) of asphalt emulsion and 691 gallons (2,616
liters) of water and features a 65-gallon (246-liter) stainless steel additive
tank. The pugmill, conveyor and all liquid material tanks are removable for
easy cleaning. All tanks are bolted in rather than welded, adding extra
durability and improving ease of maintenance. The asphalt emulsion and water
tanks are separate components, eliminating possible rust-through and
contamination of products. The M212 has a full-width working platform that
allows operators to easily see both sides of the unit, the spreader box and the
material being placed. In addition, a remote sideshift control lets the
spreader box operator control the box from the ground.

 

Pavement preservation methods
such as the slurry seal and micro surfacing treatments applied by the M212 use
fewer natural resources (e.g., aggregate, binder, etc.), consume less energy
and reduce overall greenhouse gas emissions when compared to traditional
pavement reactive maintenance and repair methods.

 

Aggregate is delivered to the
M212’s pugmill by a belt-over-chain conveyor to eliminate slippage. Steep
hopper walls minimize bridging, while the hopper’s polyethylene lining reduces
friction. This eliminates the need for a vibrator, which decreases problems
with loose bolts and

damage to welds and components.
The asphalt emulsion ratio is regulated as it is pumped by the large 3-inch
gear pump into the pugmill—where they are mixed with the aggregate. The
variable speed, dual-shaft, multi-paddle pugmill has a dual hydraulic drive,
which provides even mixture and coating of the aggregate.

 

The M212 has a proven design
with convenient control locations and good operator visibility. The unit is
powered by an onboard 99-horsepower Cummins diesel engine located at the front
of the unit in an enclosed engine compartment that reduces noise for the driver
and crew.  The unit provides flexibility
to better manage legal load weight restrictions by adding additional axles,
including one behind the drive axle—which increases the wheelbase and helps
meet the Federal bridge law.

 

The M212 is part of Bergkamp’s
M2 Series of slurry seal and micro surfacing pavers, which also includes the
truck-mounted M206, M208 and M210 and the trailer-mounted M216 paver.
