RHEOLOGY OF BITUMENS AND THE PARALLEL PLATE MICROVISCOMETER

THE VISCOELASTIC BEHAVIOR OF BITUMENS VARIES WITH FILM THICKNESS. THEREFORE, FOR CORRELATION OF LABORATORY TESTING WITH FIELD PERFORMANCE IN BITUMINOUS PAVEMENTS, IT IS IMPORTANT TO MATCH THE GEOMETRY OF TESTING TO GEOMETRY OF END USE. THE PARALLEL PLATE MICROVISCOMETER IS WELL SUITED FOR THIS WORK, BUT THE TOTAL DISPLACEMENT SUGGESTED BY PREVIOUS AUTHORS FOR MOST PAVING ASPHALTS IS TOO LOW. ROTATING PARALLEL PLATES HAVE BEEN USED TO EXTEND THE USEFUL RANGE OF THE MICROVISCOMETER. /AUTHOR/
