Document Summary

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program prepared by the New Jersey Department of Transportation (NJDOT) for its Winter Maintenance Program. The guidelines are based on materials adapted from the Federal Highway Administration (FHWA) and the US Army Cold Regions Research and Engineering Laboratory, Corps of Engineers' 1996 Manual of Practice for an Effective Anti-icing Program. The document establishes operational protocols for the State of New Jersey's winter road maintenance activities.

The guidelines provide comprehensive operational procedures for the application of solid de-icing chemicals across five distinct weather event scenarios: light snow storms, moderate to heavy snow storms, frost or black ice conditions, freezing rain storms, and sleet storms. For each weather scenario, the document specifies pavement temperature ranges, initial and subsequent maintenance actions, chemical spread rates measured in pounds per lane-mile, application timing requirements, and operational comments. Chemical spread rates vary by weather condition and temperature, ranging from 150 to 400 pounds per lane-mile for initial operations and 150 to 350 pounds per lane-mile for subsequent operations. The guidelines emphasize the timing and frequency of chemical applications to prevent deteriorating conditions or development of packed and bonded snow, recommend pre-wetting and solid chemical applications, and mandate plowing operations before chemical applications to ensure proper pavement contact. The document does not contain pricing information, contract amounts, or procurement terms.
