STRUCTURAL COMPOSITION OF ASPHALTIC CONCRETE /IN RUSSIAN/

THE THREE STRUCTURAL SYSTEMS OF ASPHALTIC CONCRETE ARE DESCRIBED USING THE STANDARD CONCEPTS OF PHYSICO-CHEMICAL MECHANICS. EACH SYSTEM CONSISTS OF TWO PHASES: A DISPERSING AGENT AND A DISPERSED PHASE, HENCE THE REPRESENTATION OF ASPHALTIC CONCRETE BY THE SUPERPOSITION OF THREE STRUCTURES: A MICROSTRUCTURE FORMED BY THE FILLER AND BITUMEN, A MESOSTRUCTURE FORMED BY THE SAND-FILLER-BITUMEN, AND A MACROSTRUCTURE FORMED BY THE ADDITION OF CRUSHED ELEMENTS TO THE PREVIOUS STRUCTURE. THE MECHANICAL PROPERTIES OF EACH SYSTEM HAVE BEEN STUDIED FOR VARIOUS PROPORTIONS OF THE DISPERSED PHASE. CURVES AND TABLES SHOW HOW TO SELECT AN OPTIMUM FILLER/BITUMEN PROPORTIONING WHEN THE VISCOSITY OF THE BITUMEN IS KNOWN, AND AN OPTIMUM BITUMEN/CRUSHED MATERIAL PROPORTIONING FOR A GIVEN ASPHALTIC CONCRETE MACROSTRUCTURE. ATTENTION IS DRAWN TO THE INFLUENCE OF MANUFACTURING CONDITIONS AND STRUCTURE ON THE MECHANICAL BEHAVIOR OF ASPHALTIC CONCRETE. /LCPC(A)/RRL/
