T0777 Attachment 5 - Spreading Services Guide.pdf

This document is the Solid Chemical Application Guidelines for an Effective Anti-icing Program prepared by the New Jersey Department of Transportation. The guidelines were developed based on materials 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. These guidelines establish statewide standards for winter maintenance operations in New Jersey.

The document provides comprehensive application guidance 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. For each weather event, the guidelines specify chemical spread rates measured in pounds per lane-mile, maintenance actions, application timing, and operational protocols organized by pavement temperature ranges. Chemical application rates vary based on weather conditions and temperatures, ranging from 150 to 350 pounds per lane-mile during initial operations and subsequent applications. The guidelines emphasize proactive treatment strategies, including pre-wetting solid chemicals, plowing requirements, and monitoring protocols. Key operational principles include timing chemical applications to prevent deteriorating conditions and packed snow development, applying chemicals ahead of traffic rush periods, and plowing before chemical applications to ensure excess snow, slush, and ice removal. No pricing terms, contract amounts, option periods, or vendor information are included in this document, as it functions as an operational standards manual rather than a procurement contract.
