T0777 Attachment 5 - Spreading Services Guide.pdf

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program developed by the New Jersey Department of Transportation (NJDOT). The guidelines are based on the Manual of Practice for an Effective Anti-icing Program prepared by the Federal Highway Administration (FHWA) and the US Army Cold Regions Research and Engineering Laboratory, Corps of Engineers in 1996. The document serves as operational guidance for the NJDOT Winter Maintenance Program and establishes standards for solid chemical applications across New Jersey's transportation network.

The document provides detailed operational protocols for solid chemical application across five distinct weather scenarios: light snow storms, moderate or heavy snow storms, frost or black ice conditions, freezing rain storms, and sleet storms. For each weather event, the guidelines specify chemical spread rates measured in pounds per lane-mile (lb/lane-mi), ranging from 150 to 400 lb/lane-mi depending on temperature ranges and pavement conditions. Initial operation chemical spread rates typically range from 150 to 250 lb/lane-mi for snow conditions, while subsequent operations range from 150 to 350 lb/lane-mi. For freezing rain and sleet conditions, rates escalate to 250 to 350 lb/lane-mi. The guidelines are temperature-dependent, with specific protocols for conditions above 32°F, between 15°F and 32°F, and below 15°F. No pricing terms, contract amounts, set asides, or option periods are specified in this operational guidance document, as it functions as a technical standards manual rather than a procurement contract.
