Document Summary

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program issued by the New Jersey Department of Transportation. The guidelines were adapted from the Manual of Practice for an Effective Anti-icing Program prepared by the Federal Highway Administration (FHWA), U.S. Army Cold Regions Research and Engineering Laboratory, Corps of Engineers (1996). This is a technical guidance document rather than a formal contract award, serving the New Jersey Department of Transportation's Winter Maintenance Program.

The document provides operational guidelines for the application of solid de-icing chemicals 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 application rates measured in pounds per lane-mile (lb/lane-mi), ranging from 150 to 400 lb/lane-mi depending on pavement temperature, weather conditions, and operational phase (initial versus subsequent applications). The guidelines recommend no chemical application below 15°F, plow-only operations, or abrasive applications for enhanced traction in extreme cold. Chemical spread rates vary with pavement surface conditions (dry, wet, slush, or snow cover) and precipitation intensity, with higher rates recommended during heavier precipitation periods and lower rates during lighter accumulation. The document includes detailed operational notes on timing, frequency of applications, and conditions requiring adjustment of chemical rates to accommodate longer operational cycles or increased traffic volumes.
