T0777 Attachment 5 - Spreading Services Guide.pdf

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's US Army Cold Regions Research and Engineering Laboratory, Corps of Engineers (1996). These guidelines apply to the New Jersey Department of Transportation's Winter Maintenance Program and provide operational standards for the application of solid chemicals during winter weather events.

The document contains five comprehensive tables (Tables 5-9) that specify maintenance and chemical application protocols based on pavement temperature ranges, weather conditions, and operational phases. The guidelines address four distinct weather events: light snow storms with moderate or heavy snow periods, moderate or heavy snow storms, frost or black ice conditions, freezing rain storms, and sleet storms. For each weather scenario, the tables prescribe initial and subsequent chemical spread rates measured in pounds per lane-mile, maintenance actions, and specific operational recommendations. Chemical application rates range from 150 to 350 pounds per lane-mile depending on temperature, precipitation intensity, and traffic conditions. The guidelines emphasize proactive chemical application ahead of traffic rush periods, increased application rates during heavier precipitation events, and the reduction of chemical rates during lighter snow conditions. No pricing information, contract amounts, option periods, or vendor details are included in this operational guidance document.
