NEW METHOD OF CALCULATING THE COMPLEX MODULUS OF BITUMINOUS MIXTURES

NOUVELLE METHODE DE CALCUL DU MODULE COMPLEXE DES MELANGES BITUMINEUX

A CALCULATION METHOD IS PROPOSED, WHICH CAN BE APPLIED TO ALL BITUMINOUS MIX-DESIGNS, FROM MASTICS TO OPEN-GRADED MIXTURES. THE STIFFNESS MODULUS AND THE ANGLE OF LOSS CAN BE DETERMINED EITHER BY MEANS OF TWO MONOGRAMS OR WITH A CALCULATION PROGRAM. COMPLEX MODULI OF 12 MIXTURES ARE MEASURED UNDER DYNAMIC CONDITIONS ON TRAPEZOIDAL SAMPLES SUBJECTED TO ALTERNATE BENDING STRESSES. THE COMPARISON OF THESE MEASURED MODULI AND CALCULATED MODULI LEADS TO A MAXIMUM DEVIATION CORRESPONDING TO A MULTIPLYING FACTOR OF 1,5, IF THE BINDER IS SUFFICIENTLY RIGID. FOR THE COVERING ABSTRACT, SEE IRRD ABSTRACT NO 107043.
