Bergkamp’s M210 Truck-Mounted Slurry Seal & Micro Surfacing Paver Lengthens Pavement Life
Bergkamp Inc., based in Salina, KS, offers the M210 truck-mounted slurry seal and micro surfacing paver to deliver one of the most efficient methods of preventive maintenance for highways, roads and parking lots—which can extend the life of pavement by up to seven or more years. Slurry seal and micro surfacing is a mixture of aggregate, asphalt emulsion, water and additives that is applied over existing pavement as one smooth layer. The truck-mounted M210 can carry 10.5 yd3 (8.0 m3) of aggregate in a level struck load, 600 gallons (2,271 liters) of asphalt emulsion and 600 gallons (2,271 liters) of water. It 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 M210 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. It provides flexibility to better manage legal load weight restrictions by adding up to three tag axles, including one behind the drive axle—which increases the wheelbase and helps meet the Federal bridge law.
Aggregate is delivered to the 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. Asphalt emulsion is delivered to the pugmill by a positive displacement heat jacketed gear pump. The pump is powered by a jackshaft that is common to the aggregate conveyor to provide a consistent asphalt emulsion-to-aggregate ratio. The variable speed, dual-shaft, multi-paddle pugmill has a dual hydraulic drive, which provides even mixture and coating of the aggregate.
The M210 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.
The M210 is part of Bergkamp’s M2 Series of truck-mounted slurry seal and micro surfacing pavers, which also includes the M206, M208 and M212.
