BINDERS AND AGGREGATES FOR BITUMINOUS MIXTURES

LIGANTES Y ARIDOS PARA MEZCLAS BITUMINOSAS

THIS REPORT IS IN TWO PARTS. PART 1 IS DEVOTED TO THE STUDY OF AGGREGATES USED IN BITUMINOUS MIXTURES AND EMPHASIZES THE IMPORTANCE OF THE RAW MATERIAL, MANUFACTURING PROCESS OF THE AGGREGATES WHICH INFLUENCES THE QUALITY OF THE AGGREGATE OBTAINED, EXTRACTION, CRUSHING, CLASSIFICATION AND SUPPLY, AND THE PROPERTIES OF DIFFERENT DIMENSIONS OF AGGREGATES: COARSE, FINE AND FILLER; DETAILS ARE ALSO GIVEN OF STANDARDIZED TESTS FOR DETERMINING THE ABOVE CHARACTERISTICS DEPENDING ON THE RESPECTIVE AGGREGATES STUDIED, AND OF THE PROBLEMS ARISING FROM THE WRONG USE OF AGGREGATES. ATTENTION IS DRAWN TO FINE AGGREGATES, WHICH OFTEN LEAD TO FAILURE, AND TO THE FUNCTION OF EACH SIZE OF AGGREGATES IN THE BITUMINOUS MIXTURE. PART 2 DEALS WITH BITUMINOUS BINDERS, THE PREPARATION, MIX DESIGN AND NATURE OF BITUMEN AND TAR, MAIN PROPERTIES (ADHESION, RHEOLOGICAL BEHAVIOUR, AGEING, ETC), AND RESPECTIVE TESTS CARRIED OUT FOR THEIR DETERMINATION. RECOMMENDATIONS ARE PUT FORWARD FOR THE SELECTION OF THE CORRECT BINDER AS A FUNCTION OF SERVICE TEMPERATURE, RATE OF LOAD APPLICATION, ETC. IT IS CONCLUDED THAT FURTHER RESEARCH ON THE TECHNOLOGICAL BEHAVIOUR OF BITUMINOUS BINDERS SHOULD BE CONDUCTED. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 106958.
