T0777 Attachment 5 - Spreading Services Guide.pdf

This document is a Solid Chemical Application Guidelines manual for the New Jersey Department of Transportation's Winter Maintenance Program. The guidelines are based on and modified from the Manual of Practice for an Effective Anti-Icing Program prepared by the Federal Highway Administration (FHWA) and the U.S. Army Cold Regions Research and Engineering Laboratory, Corps of Engineers (1996). The document establishes operational standards for a single state agency rather than a multi-jurisdictional consortium or procurement contract.

The document provides operational guidance for applying solid chemical de-icers across five distinct weather event scenarios: light snow storms, moderate to heavy snow storms, frost or black ice conditions, freezing rain storms, and sleet storms. For each weather event, the guidelines specify pavement temperature ranges, chemical application rates (measured in pounds per lane-mile), maintenance actions, and operational procedures. Chemical spread rates vary significantly based on conditions, ranging from 150 to 400 pounds per lane-mile, with higher rates applied during more severe weather or lower temperatures. The guidelines emphasize pre-wetting solid chemicals, timing applications ahead of traffic rush periods, and adjusting chemical rates based on precipitation intensity and pavement temperature trends. No pricing terms, vendor information, or contract amounts are specified in this operational manual, which serves as an internal procedural document for winter maintenance operations rather than a procurement contract.
