Book Description
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.

Book Description
Some background information is given together with the scope and objectives of a 5-year, Joint Winter Runway Friction Measurement Program between the National Aeronautics & Space Adminstration (NASA), Transport Canada (TC), and the Federal Aviation Administration (FAA). The primary objective of this effort is to perform instrumental aircraft and ground vehicle tests aimed at identifying a common number that all the different ground vehicle devices would report. This number, denoted the International Runway Friction Index (IRFI), will be related to all types of aircraft stopping performance. The range of test equipment, the test sites, test results and accomplishments, the extent of the substantial friction database compiled, and future test plans will be described. Several related studies have also been implemented including the effects of contaminant type on aircraft impingement drag, and the effectiveness of various runway and aircraft de-icing chemical types, and application rates.
