Title:

Role of Performance Specifications in Developing a Quality Control System for Winter Maintenance

Abstract:

Effective winter maintenance makes use of freezing point depressant chemicals to prevent the formation of the bond between snow and ice and the highway pavement. In performing such winter maintenance, the selection of appropriate chemicals for the bond prevention task involves consideration of a number of factors. The factors are, in essence, performance measurements of the chemical, and as such can be incorporated easily into a specification document to allow for selection of the best chemicals for a given agency to use in its winter maintenance activities. Once performance measures for deicing or anti-icing chemicals have been specified, this allows the creation of a quality control program for the acceptance of those chemicals. This paper presents a series of performance measurement tests for chemicals and discusses the role that they can play in such a quality control program. Applying quality control to the chemicals as received is only part of a much broader quality program. This paper explores how the quality control of chemicals can be extended into a program that applies quality measures throughout winter maintenance activities.
