T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, which establishes standardized operational procedures for snow removal services on state highways. The guide serves as an instructional manual for contractors and NJDOT personnel responsible for winter road maintenance operations throughout New Jersey.

The guide provides detailed technical specifications and deployment standards for snow plowing operations across various highway configurations, including two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, and multi-lane divided highways with raised or depressed medians. For each configuration, the document specifies truck positioning, spacing intervals, directional plow orientation, and overlap requirements to ensure comprehensive snow removal and optimal traffic flow. Operational standards include truck spacing of 100 to 500 feet depending on highway type, with overlap ranges of two to 100 feet between successive plowing passes. Additional guidance covers specialized applications such as jughandle intersections and switch-back curve ramps, with recommendations for equipment types, including power-reversible plows and graders, to maximize efficiency and minimize thawing-refreezing cycles. The guide emphasizes progressive snow management techniques and provisions for additional truck deployment when multiple lanes require servicing, establishing baseline performance metrics for NJDOT snow removal contracts.
