T0777 Attachment 5 - Spreading Services Guide.pdf

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program prepared by the New Jersey Department of Transportation (NJDOT). The guidelines are based on the Manual of Practice for an Effective Anti-Icing Program originally developed by the Federal Highway Administration (FHWA) and the US Army Cold Regions Research and Engineering Laboratory, Corps of Engineers in 1996. These guidelines establish operational protocols for the Winter Maintenance Program administered by NJDOT.

The guidelines provide detailed specifications for solid chemical application rates and maintenance procedures across five distinct weather events: light snow storms, moderate to heavy snow storms, frost or black ice conditions, freezing rain storms, and sleet storms. Chemical application rates range from 150 to 350 pounds per lane-mile depending on pavement temperature, weather conditions, and precipitation intensity. For each weather event category, the document specifies initial operation and subsequent operations procedures, including maintenance actions and chemical spread rates tailored to temperature ranges above 32°F, between 32°F and 15°F, and below 15°F. The guidelines emphasize proactive chemical application ahead of traffic rush periods, plow operations before chemical applications to remove excess precipitation, and increased application frequencies during heavier snow or precipitation events. No pricing information, contract amounts, option periods, or renewal terms are included in this guidance document, which functions as operational standards rather than a procurement contract.
