Document Summary

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

The document provides comprehensive operational guidance for the application of solid chemical de-icers across five weather event 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 pavement temperature ranges, initial and subsequent maintenance actions, chemical spread rates measured in pounds per lane-mile, and operational recommendations. Chemical application rates vary by temperature and weather severity, ranging from no application above 32°F with steady or rising temperatures to rates of 150-400 lb/lane-mi under more severe conditions. The guidelines emphasize pre-application timing to prevent ice adhesion, coordination with plowing operations, and adjustment of application rates based on precipitation intensity and pavement conditions. No pricing terms, contract amounts, set asides, or renewal periods are specified in this guidance document.
