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 adapted from the Manual of Practice for an Effective Anti-icing Program originally developed by the Federal Highway Administration (FHWA), US Army Cold Regions Research and Engineering Laboratory, and the Corps of Engineers in 1996. The document serves as a technical reference for the Winter Maintenance Program under New Jersey's transportation authority.

The document provides operational guidance 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 type, the guidelines specify application rates measured in pounds per lane-mile, maintenance actions, and chemical spread rates differentiated by pavement temperature ranges and trend conditions. Chemical application rates vary by weather event and temperature, ranging from 150 to 400 pounds per lane-mile for initial operations and 150 to 400 pounds per lane-mile for subsequent operations. The guidelines emphasize pre-wetting solid chemicals to enhance effectiveness, timing applications ahead of traffic rush periods, plowing before chemical applications to remove excess accumulation, and monitoring pavement conditions closely. No pricing terms, contract amounts, or renewal periods are specified in these technical guidelines, which function as operational procedures rather than a procurement or service contract.
