INVESTIGATION INTO THE RHEOLOGY OF BITUMINOUS MORTAR WITH LIMESTONE DUST

RHEOLOGISCHE UNTERSUCHUNGEN BITUMINOESER MOERTEL MIT KALKSTEINMEHL

PREVIOUSLY PUBLISHED INFORMATION CONCERNING THE ROLE OF THE FILLER ONLY OCCASIONALLY REFERS TO THE BINDER ITSELF AND THE INTERACTION BETWEEN BINDER AND MINERAL. THE PURPOSE OF RECENT INVESTIGATIONS WAS TO DETERMINE WHETHER THE DIFFERENT ORIGINS OF THE RESPECTIVE BITUMENS INFLUENCED THE RHEOLOGICAL QUALITIES OF THE MORTAR FORMED FROM BINDER AND FILLER. THE RESULTS OF THE EXPERIMENTS INDICATE THAT THE RHEOLOGICAL CHARACTERISTICS OF THE BITUMEN ITSELF, E.G. VISCOSITY, ARE OF GREAT SIGNIFICANCE UPON THE RHEOLOGICAL QUALITIES OF THE ASPHALT MORTAR IN RELATION TO THE FILLER QUANTITY. ACCORDINGLY DIFFERENT QUANTITIES OF BITUMEN HAVING THE SAME PENETRATION BUT FROM DIFFERING SOURCES MAY BE NECESSARY TO ACHIEVE MORTARS OF THE SAME VISCOSITY AT LAYING TEMPERATURE. IN CONTRAST NO INFLUENCE COULD BE DETECTED FROM THE USE OF VARYING PARTICLE SIZE DISTRIBUTION IN THE FILLER. IN PRACTICAL TERMS THESE RESULTS SHOW THE NECESSITY TO DESIGN NEW MIXES WHENEVER DIFFERENT TYPES OF BITUMEN SOURCES ARE USED.
