A Tier 4 truck engine that fulfills stringent emissions regulations powers the M310CS truck-mounted slurry seal and micro-surfacing paver. Bergkamp is the manufacturer.

With its PTO-driven hydraulic pumps, the M310CS doesn’t need a side engine – along with its associated emissions, noise and vibration. The unit delivers the power and performance equal to the side engine package that is standard on the company’s M310 Paver.

The model uses the EMCAD (Electronic Mix Control and Diagnostic) System, which is designed to manage power inputs and electronically control material outputs to maintain the desired mix design.

The field-proven EMCAD System displays current and average material ratios, total material used and material application rates – allowing operators to easily calibrate the machine, control production rates and simplify maintenance. EMCAD can produce on-demand reports to track production for individual sections of the job, or the entire job, via an onboard printer. Operators can evaluate these printouts and make the necessary adjustments to more efficiently run the machine and calculate job efficiencies and the bottom line.

The M310CS uses direct-drive hydraulics that are controlled by the EMCAD System. The system monitors and adjusts material ratios automatically according to the set points of the ingredients, production control setting and instantaneous feedback from the delivery system sensors to provide consistent mix. Aggregate, asphalt emulsion, water, additive and fines are proportionally delivered and metered according to the set points, as per mix design. In addition, it electronically self-diagnoses control system and displays a simple error code, reducing troubleshooting and repair time. Calibration is simplified, so fewer steps are required and manual calculations are eliminated. Even less experienced operators can quickly make adjustments during production without compromising the accuracy of the mix.

The M310CS carries 10 cubic yards of aggregate, 630 gallons of both asphalt emulsion and water and 80 gallons of additive. The operator interface console on the paver has easy-to-use joystick controls and slides to either side to provide the operator with the best available view. The pugmill safely slides out for easier cleaning; the bottom bowl stays in the paver, while the excess material falls out of the bottom for a fast cleaning job. The low position of the fines feeder makes it easily accessible for loading. All liquid tanks are removable for maintenance.

Aggregate is delivered to the pugmill by a 24-inch-wide belt-over-chain conveyor, which eliminates slippage, while the steep hopper walls minimize bridging problems. A positive displacement pump, three-way valve and inline strainer allow trouble-free loading of asphalt emulsion onto the truck, so new material can be loaded at full rate without affecting the production settings.

Bergkamp has been manufacturing pavement maintenance equipment since 1980. It offers a line of truck-mounted, trailer-mounted and continuous slurry seal and micro surfacing pavers and equipment, as well as spray injection and all-in-one pothole patching equipment.
