EXAMINATION OF THE REPORT OF THE TECHNICAL COMMITTEE ON PAVEMENT DESIGN

THE SESSION ON GENERAL HIGHWAY MATTERS WAS OPENED BY M. ANDRE SACCASYN OF BELGIUM WHO PRESENTED A REPORT PROPOSING SUBJECTS AND QUESTIONS WHICH BENEFIT FROM INTERNATIONAL EXCHANGE OF INFORMATION. THESE INCLUDED: (1) PERFORMANCE OF EXPERIMENTAL ROADS UNDER CLIMATIC CONDITIONS OF DIFFERENT COUNTRIES, (2) APPLICATION OF PROBABILITY CONCEPTS TO MATERIAL CHARACTERISTICS AS WELL AS TO TRAFFIC CHARACTERISTICS FOR ROAD DESIGN, (3) STUDY OF VIBRATION EFFECTS DURING DYNAMIC LOADING, (4) COMPARATIVE STUDY OF PAVEMENT COMPOSITIONS, (5) INSTRUMENTATION FOR MEASUREMENT OF SURFACE TEXTURE, (6) INVESTIGATION OF SURFACE TEXTURE MEASUREMENTS AT VARIOUS SPEEDS, (7) PROBLEMS OF SURFACE WATER DISPOSAL AND FORMATION OF BLINDING MISTS, (8) IMPROVEMENT OF SUBSOIL DRAINAGE, AND (9) NOISE PROBLEMS. THE DISCUSSION PERIOD FOLLOWING INCLUDED TALKS ON: (1) MEASUREMENTS OF STRESSES AND STRAINS IN ASPHALT, GIVEN BY DR. DEMPWOLFF OF FEDERAL GERMANY; (2) APPLICATION OF NEW METHODS AND MATERIALS IN HIGHWAY CONSTRUCTION BY DESIGNERS IN GREAT BRITAIN, GIVEN BY MR. H. N. GINNS; (3) SKIDDING PROBLEMS AND THE SEARCH FOR SATISFACTORY RUGOSITY OF BITUMINOUS PAVEMENTS, GIVEN BY M. HOLOFFE OF BELGIUM; (4) DISTINCTION OF PAVEMENT DESIGN FACTORS BETWEEN ASPHALT AND CONCRETE PAVEMENTS, GIVEN BY MR. KOBAYASHI OF JAPAN; (5) PAVEMENT DESIGN PRACTICES IN USSR, GIVEN BY MR. KRIVISSKY; (6) PROBLEMS OF PAVEMENT STRENGTH AND IMPROVEMENT OF QUALITY OF MATERIALS, GIVEN BY M. PASQUET OF FRANCE; AND (7) THE DISTINCTION BETWEEN ROADWAY CHARACTERISTICS AND VEHICLE CHARACTERISTICS IN CONSIDERATION OF ROAD SURFACE DESIGN, GIVEN BY MR. W. N. CAREY OF USA. THE PRESENTATIONS WERE FOLLOWED BY CONSIDERATION OF THE REPORT OF THE TECHNICAL COMMITTEE ON PAVEMENT DESIGN. THE REPORT WAS COMPILED FROM QUESTIONNAIRE REPLIES FROM VARIOUS COUNTRIES AND INCLUDED INFORMATION ON THICKNESSES OF VARIOUS PAVEMENT COURSES, MECHANICAL CHARACTERISTICS OF PAVEMENTS IN TERMS OF THE NATURE OF THE TRAFFIC, GEOTECHNICAL CHARACTERISTICS OF THE SUBGRADE, DRAINING CONDITIONS, AND CLIMATIC CONDITIONS. COMMENTS WERE MADE ON TECHNICAL ASPECTS OF THE REPORT, THE NEED FOR CONTINUOUS REVIEW OF DESIGN METHODS, AND THE NEED FOR FULLER EXPLANATIONS OF NOMENCLATURE DUE TO LANGUAGE BARRIERS.
