PROPORTIONING OF BITUMINOUS MIXTURES: (1) DEFINITION AND TYPES OF MIXTURES. PROPERTIES REQUIRED

DOSIFICACION DE MEZCLAS BITUMINOSAS: I. MEZCLAS BITUMINOSAS, DEFINICION Y TIPOS DE MEZCLAS. PROPIEDADES QUE DEBEN CUMPLIR

This paper deals with the definition, the types and the properties of bituminous mixtures. These are defined as heterogeneous materials produced by the mixing of aggregates, filler and a bituminous binder, including in the mass a proportion of air. The various different types of mixtures are examined: bituminous macadam, bituminous mixtures, hot rolled asphalt, gussasphalt and mastic asphalt, giving the characteristics and the range of use in each case. The properties which these mixtures should possess and which are desirable are stability, flexibility, fatigue strength, tensile strength, durability, impermeability, resistance to skidding and workability. These properties should be envisaged as a function of the parameters of the structure for which the mixture is intended and of the materials available. Finally, the rheology of the mixture is studied, that is the behaviour of the state of stress - deformation produced in the mixture by the application of loads under the environmental conditions of the road. This article was presented at a course on proportioning bituminous mixtures, which took place at the Civil Engineering and Architectural Research Centre at Madrid on 1st-5th March 1976. /TRRL/
