Title: GUIDANCE FOR SUCCESSFUL ANTI-ICING OPERATIONS BASED ON U.S. EXPERIENCE
Accession Number: 00745783

Availability: Find a library where document is available Abstract: Highway anti-icing is the snow and ice control practice of preventing the formation or development of bonded snow and ice by timely applications of a chemical freezing-point depressant. The application of a chemical freezing-point depressant onto a highway pavement when a winter storm starts or before precipitation begins inhibits the development of a bond between snow and ice and the pavement surface. Moderate, periodic reapplication of the chemical during the storm can continue this effect. Such preventative operations are the core of an anti-icing program. Guidance for successful anti-icing operations has been developed. This guidance is based on an analysis of data obtained during the winters of 1993-1994 and 1994-1995 in the 15 states participating in Federal Highway Administration (FHWA) Test and Evaluation Project 28 and also on relevant experiences and the review of anti-icing practices in Strategic Highway Research Project H-208. Specific and concise guidance for anti-icing operations for six winter weather events has been formulated. The maintenance action for each event is defined for several pavement temperature ranges and associated temperature trends, and for initial and follow-up operations. The actions include application of chemicals, either alone or in combination with plowing, application of abrasives, plowing only, or doing nothing. Solid, liquid, and prewetted solid chemical application rates are suggested as appropriate. This guidance is found in the FHWA "Manual of Practice for an Effective Anti-Icing Program: A Guide for Highway Winter Maintenance Personnel" (FHWA-RD-95-202).
