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 (NJDOT) and based on standards established by the Federal Highway Administration (FHWA), the US Army Cold Regions Research and Engineering Laboratory, and the Corps of Engineers. The guidelines serve as a technical resource document for winter maintenance operations managed by NJDOT.

The document provides operational guidance for the application of solid chemical de-icing agents 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 condition, the guidelines specify appropriate chemical spread rates measured in pounds per lane-mile, differentiate between initial operations and subsequent maintenance actions, and establish temperature thresholds that determine whether chemical application, mechanical plowing, or abrasive materials should be employed. Chemical application rates range from 150 to 350 pounds per lane-mile depending on weather severity and pavement temperature. The guidelines emphasize timing protocols, such as applying pre-wetted solid chemicals 1 to 2 hours in advance of freezing conditions and applying chemicals ahead of traffic rush periods. No pricing terms, contract amounts, or renewal periods are specified, as this document functions as an operational manual and technical standard rather than a procurement contract.
