REPORTS PRESENTED AT THE FEDERAL CONGRESS OF UNIVERSITIES ON THE STRENGTH OF PAVEMENTS /IN RUSSIAN/

A CONFERENCE WAS HELD TO REVIEW RESEARCH CONDUCTED DURING THE PREVIOUS FIVE YEARS INTO THE STRENGTH OF PAVEMENTS. THE REPORTS PRESENTED AT THE CONFERENCE ARE AS FOLLOWS: STATE OF THE ART AND FUTURE DEVELOPMENTS OF METHODS OF FLEXIBLE PAVEMENT DESIGN; THEORIES OF FLEXIBLE PAVEMENT DESIGN THROUGHOUT THE WORLD; PRINCIPLES OF THE CALCULATION OF THE MECHANICAL STRENGTH OF PAVEMENTS; HYPOTHESES FOR THE SEPARATE CALCULATION OF THE SHEARING STRENGTH OF ASPHALTIC CONCRETE SURFACINGS AS A FUNCTION OF THE EFFECTS OF LOADING; PROBLEM OF A RIGID PLATE OF ANY SHAPE SUBJECTED TO A VERTICAL LOAD AND RESTING ON AN ELASTIC OR GRANULAR MEDIUM CONSIDERED AS A PROBLEM OF LINEAR PROGRAMMATION; DESIGN OF FLEXIBLE PAVEMENTS CONSIDERED AS DISCRETE MEDIA; STRAIN/STRESS STATE OF PAVEMENTS TAKING INTO ACCOUNT THE MODULUS OF ADHESION BETWEEN LAYERS; VARIATIONS IN TYPES OF MULTILAYER PAVEMENT DIAGRAMS; VISCOUS PROPERTIES OF PAVEMENTS; PAVEMENT DESIGN IN FRANCE; ANALYSIS OF THE VISCO-ELASTIC DEFORMATION OF FLEXIBLE PAVEMENT LAYERS BY MEANS OF MECHANICAL DIAGRAMS; SOME ASPECTS OF THE DESIGN OF A VISCO-ELASTIC THREE-LAYER PAVEMENT; SPECIAL FEATURES OF DEEP COMPRESSIVE STRESS DISTRIBUTION IN SOIL AND PAVEMENT LAYERS; REMARKS ON THE CLASSIFICATION OF PAVEMENTS; INTERACTION OF CARRIAGEWAYS AND DYNAMIC LOADS; DETERMINATION OF THE MODULUS OF ELASTICITY OF SOIL-CEMENT; STATE OF STRESS AND DEFORMATION OF PULVERIZED SOIL FOUNDATIONS; IMPROVEMENT OF RIGID PAVEMENT DESIGN; ESTABLISHMENT OF ECONOMIC ROAD STRUCTURE PROJECTS; TECHNICAL AND ECONOMICAL MAINTENANCE OF THE SURFACE CHARACTERISTICS AND DURABILITY OF CARRIAGEWAYS; CALCULATION OF THE THICKNESS OF THE PAVEMENT FROM THE POINT OF VIEW OF ITS RESISTANCE TO FROST (THERMAL STABILITY); PREDICTING THE MOISTURE CONTENT OF THE FORMATION SOIL IN ORDER TO DETERMINE THE CORRESPONDING MECHANICAL PROPERTIES; CALCULATION OF PERMISSIBLE SWELLING CAUSED BY FROST; DESIGN AND CONCEPT OF THE "PAVEMENT/SOIL FORMATION" SYSTEM FROM THE POINT OF VIEW OF HYDROTHERMAL CONDITIONS; CALCULATION OF THE STRENGTHENING OF PAVEMENTS AFTER ELASTIC DEFLECTIONS; USE OF THE DIRECTIVES FOR PAVEMENT DESIGN DRAWN-UP BY THE MADI AND CNIL FOR ROADS IN THE GUSHOSDOR DISTRICT; MEASUREMENT OF PAVEMENT DEFLECTION UNDER THE WHEEL OF A LORRY BY MEANS OF A PRECISE LEVEL; EVALUATION OF THE MECHANICAL STRENGTH OF SOIL AND ROAD SURFACINGS OF INTERMEDIATE TYPE UNDER GIVEN CLIMATIC CONDITIONS; STRUCTURE AND MECHANICAL STRENGTH OF ASPHALTIC CONCRETE; STUDY OF THE STRENGTH OF AND STRUCTURAL PHENOMENA IN PAVEMENT CONCRETE; STRUCTURE AND MECHANICAL PROPERTIES OF UPPER PAVEMENT LAYERS CONTAINING LOW-STRENGTH AGGREGATES TREATED WITH BITUMEN; RELATIONS BETWEEN THE STRUCTURE AND MECHANICAL PROPERTIES OF ASPHALTIC CONCRETE; FATIGUE STRENGTH OF FLEXIBLE PAVEMENTS; DURABILITY INDEX OF CHIPPINGS IN FLEXIBLE PAVEMENT STABILIZED LAYERS; LOAD DISTRIBUTION OVER THE WIDTH OF THE ROAD; DETERMINATION OF THE THERMAL AND PHYSICAL CHARACTERISTICS OF SOIL-CEMENT; COMPLEX PROBLEM OF A MULTILAYER HALF-SPACE. /LCPC/RRL/
