Bergkamp’s M212 Slurry Seal, Micro Surfacing Paver Carries More

The truck-mounted M212 can carry 12 cu. yd. (9.2 cu m) of aggregate in a level struck load, 691 gal. (2,616 L) of asphalt emulsion and 691 gal. (2,616 L) of water and features a 65-gal. (246 L) stainless steel additive tank.

Bergkamp Inc., based in Salina, Kan., offers the M212 truck-mounted slurry seal and micro surfacing paver that increases production capabilities and minimizes potential greenhouse gas emissions. With multiple units sold throughout the world, the M212 is Bergkamp’s largest truck-mounted paver, holding more aggregate, asphalt emulsion and water to increase the square yards that can be paved per load. Ideal for jobs where distances from the stockpile are farther, the M212 delivers an efficient method of preventive maintenance for highways, roads and parking lots — which can extend the life of pavement by up to seven or more years, according to the manufacturer.

The truck-mounted M212 can carry 12 cu. yd. (9.2 cu m) of aggregate in a level struck load, 691 gal. (2,616 L) of asphalt emulsion and 691 gal. (2,616 L) of water and features a 65-gal. (246 L) 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-in. 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-hp (74 kW) 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.
