The results of this research and the available information on incidentg and accidents associ- at
4、ed with aircraft operations on wet runways clearly demonstrated a need for substantial improvements in aircraft braking and steering capabilities through improvements in,the skid resistance of runway pavements. Hence in 1965, based on the pioneering research of the British and on subsequent inchouse
5、 research at the Langley landing-loads track, NASA decided to undertake a comprehensive research program on the effectiveness of runway grooving as a means for increasing tire traction under operational conditions. The program involved many elements, such as construction of a research runway, selec-
6、 tion of test pavements, selection of groove patterns and grooving techniques, control of water levels during testing, selection and operation of test aircraft, and data acquisition. During the planning and execution of this research program, it was clear that the results would be of great interest
7、to all groups associated with aircraft operations, and the Langley Research Center worked closely with these groups in the implementation of the program. The runway, referred to as the landing research runway at NASA Wallops Station, was completed in early 1968 and flight tests were begun. On the ba
8、sis of the results obtained from the flight tests of the first two aircraft (an Air Force McDonnell Douglas F-4D and the NASA Convair 990 aircraft) and from the Joint NASA-British Ministry of Technology Skid Correlation Study and in view of the great interest expressed in the available data, NASA de
9、cided to hold a Conference on Pavement Grooving and Traction Studies on November 18 and 19, 1968, at the Langley Research Center to pre- sent the results available at this time. The objective of the conference was to provide an opportunity for all persons working in the area to present and discuss t
10、heir findings and, in many cases, their opin- ions. The 27 papers presented in this publication represent the results of that conference. It should be emphasized that this publication essentially represents a compilation of papers presented by various participating governmental and civil organizatio
11、ns as noted in the table of contents. Only limited editing was performed to provide reasonable consistency in format, with careful attention to assure the preservation of the viewpoints and conclusions of the authors. The reader should observe that the information presented was provided at an early
12、state of development in the technology and that some of the conclusions are subject to change as new and more complete information is generated in the on-going program. iii Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Nevertheless, the Langley Res
13、earch Center believes the conference provided a meaning- ful and timely evaluation of the state of the art and hopes the reader will find the results useful. The Langley Research Center wishes to express its appreciation to all authors, and to the organizations they represent, for their substantial
14、contributions to this pro- gram and for the timeliness of their responses both to the program activities and to the conference. George W.

Whitehurst Tennessee Highway Research Program SUMMARY The problem toward which most traction research is directed is
37、 to describe quanti- tatively by theory and experiment the major causes of pavement slipperiness in terms of pavement, vehicle, tire, operator, and atmospheric or precipitation parameters. Scien- tific research on the phenomenon of pavement slipperiness has been underway since the early 1920s. Some
38、of the milestones achieved in highway and runway traction research in the United States are summarized in the following listing. Highway research: (1) Research at Iowa State College (1920-1934) (2) First International Skid Prevention Conference (19 58) (3) Establishment of Committee E-17 by American
39、 Society for Testing and Materials (19 59) (4) Tappahannock skid correlation study (1962) (5) Florida skid correlation study (1967) Runway research: (1) Operation of Langley landing-loads track (1954) (2) Initial hydroplaning studies (1956) (3) FAA-NASA slush drag studies (1961) (4) Completion of la
40、nding research runway at NASA Wallops Station (1967) INTRODUCTION Everyone knows that pavements tend to become slippery to both pedestrikns and vehicles when they are wet or flooded or are covered with slush, snow, or ice; however, no bne yet has a complete understanding of the physical effects caus
41、ing this slipperiness, 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-which in turn can cause accidents. For this reason, papers on pavement traction have been produced in the United States since the late 19th century. The problem toward which mos
42、t traction research is directed is to describe quanti- tatively by theory and experiment the major causes of pavement slipperiness in terms of pavement, vehicle, tire, operator, and atmospheric or precipitation parameters. In simple terms, the objectives of this research are to define these paramete
43、rs in practical terms and then find means to control the primary parameters which cause or contribute to slipperiness. HIGHWAY RESEARCH Although published reports dealing with the phenomenon of pavement slipperiness may be found at least as early as the late 19th century (ref. l), scientific or quan
44、titative research of the phenomenon had its origin with Agg (ref. 2) in the early 1920s. Aggs investigations were continued by Moyer (ref. 3). Other agencies and individuals slowly became interested in this research area, but developments in the field were very limited until the late 1940s. In the l
45、ate 1940s and early 1950 a considerable surge of interest in pavement slipperiness occurred, sparked primarily by studies performed by Moyer in California (ref. 4), Shelburne and Sheppe in Virginia (ref. 5), Whitehurst and Goodwin in Tennessee (ref. 6), and Normann of the Bureau of Public Roads (ref
46、. 7). Perhaps the greatest impetus to progress in the field was achieved when the late Tilton E. Shelburne, Director of Research of the Virginia Council of Highway Investigation and Research, called the First International Skid Prevention Conference in Charlottesville, Virginia, for September 1958.
47、Two weeks prior to that conference, a correlation study was conducted in Virginia in an effort to determine whether test equipment then available and in use at a variety of agencies did, indeed, correlate. The test equipment included such devices as skid trailers, stopping-distance cars, and small n
48、onvehicular portable test apparatus from both the United States and abroad. Results of this correlation study presented at the international conference (ref, 8) indicated that all the available equipment agreed in the relative slipperiness ratings of the pavement surfaces. However, rather wide differences in the measured absolute value of friction coefficient existed between the different test devices, and the correlation of friction values was therefore poor. The Board of Directors of the American Society for Testing and Materials (ASTM) approved the est
