Glossary
Stockpile Treatment

The application of a highly viscous liquid material to all of or a portion of the stockpile. With abrasives (e.g., sand) it is used to reduce freezing of material in the pile. With solid deicer products, it is used to help prevent freezing and to increase performance. #EquipmentandTechniqueTerms


Glossary
Pre-wetting

Coating solid materials with liquid to increase effectiveness directly before application. Pre-wetting can be achieved in three main ways: Applied at the spinner as material leaves the spreader. Applied to each load prior to placing it in the spreader. Applied to the entire load of salt in...


Glossary
Tailgate Spreader

A piece of equipment that attaches to the back of a truck, often to the trailer hitch or vehicle frame and distributes solid deicer either by broadcasting the material with the use of a spinner, or dropping the material directly down. #EquipmentandTechniqueTerms


Glossary
Liquid Application System

Any truck-mounted spray system used to apply liquid deicers directly to the surface. #EquipmentandTechniqueTerms


Glossary
Pre-Wet Systems

Liquid application systems for pre-wetting salt in the auger or at the spinner just prior to spreading.


Glossary
Hopper Spreader

A piece of equipment with larger capacities than tailgate spreaders. Solid deicer material is normally loaded into the hopper in bulk, with a conveyor or auger system that feeds the material to the rear of the unit, dropping material onto a powered spinner assembly. Synonym: V-Box spreader.


Glossary
Calibration

Determining a precise measurement of the material output of a given deicer spreading/spraying unit under different settings and vehicle speeds. The goal of calibration is measuring and applying a consistent rate/set of output rates over time.


Glossary
Sidewalk Spreader

A piece of equipment designed to spread deicing materials (solid or liquid) in a sidewalk setting.


Glossary
Sidewalk Crew

A team of laborers tasked with clearing snow and ice from sidewalks, using any combination of operational tactics, including shoveling, deicing, and plowing with sidewalk-specific equipment. Synonym: Shovel Crew. #EquipmentandTechniqueTerms


Glossary
Windrowing

A snowplowing technique that involves angling the snowplow to the left or right while plowing, which rolls the snow toward the direction of the angle. This results in the creation of a piled trail of snow (the windrow or berm) as a way to briefly accumulate such precipitation for further...
