Pavement wear and a substantial increase in maintenance costs due to the use of studded tires is the focus of this Record.

The current state of knowledge with both studded tire performance and methods of assessing pavement wear is reported. An annotated bibliography is presented of all known research on this subject from the U.S. and European sources, a review and evaluation of the data and results of completed studies and recommendations for future research. The objectives of the study were confined to the following tests: (1) correlation of data on the frictional characteristics of studded tires on ice, packed snow, and on bare pavements, and (2) development of a method, or methods, of quantitative assessment of the difference in wearing and abrasive effects of studded versus unstudded tires on different types of surfaces. A stud-resistance coefficient for operation on ice was derived and all U.S. data are correlated with this parameter and ice temperature.

The objective of the symposium was to provide a forum for the exchange of information about state-of-the-art research and technology applications to improve snow removal and ice control operations in transportation systems. Sixty-one papers were presented in the areas of policy and management, infrastructure and snow control, materials and applications, equipment, travel surface, environment and health, road weather information systems and forecasting, and safety and visibility. Papers were authored by maintenance engineers and researchers from Austria, the Czech Republic, Denmark, Finland, Germany, Japan, New Zealand, the Netherlands, Norway, Russia, Sweden, the United Kingdom, and the United States. Twenty-one of these papers are included in this publication.
