Document Summary

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program developed by the New Jersey Department of Transportation (NJDOT) Winter Maintenance Program. The guidelines are adapted from the Manual of Practice for an Effective Anti-Icing Program originally prepared by the Federal Highway Administration (FHWA) and the US Army Cold Regions Research and Engineering Laboratory, Corps of Engineers in 1996. The document establishes operational protocols for a single jurisdiction—New Jersey—and does not involve external vendors, consortiums, or private companies.

The guidelines prescribe application rates, operational procedures, and maintenance actions for solid chemical de-icing agents across five distinct weather event scenarios: light snow storms, moderate or 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, precipitation intensity, and weather conditions. Operational guidance specifies whether initial and subsequent chemical applications should use pre-wetted or dry solid materials, with detailed recommendations for plowing, reapplication frequency, and monitoring requirements. No contract pricing, vendor information, option periods, or renewal terms are included in this technical guidance document, which serves as a procedural manual for NJDOT maintenance personnel rather than as a formal procurement or service contract.
