Laboratory Testing of Paving Mixes ? Dynamic Material Functions and Wheel Tracking Tests

Popis výsledku v původním jazyce

Five asphalt paving mixes prepared with different asphalt binders (one conventional, two oxidized, and two modified by styrene-butadien-styrene copolymer, 2% and 4% by weight) were studied in small amplitude oscillation and wheel tracking tests. The mainfocus of the study was to investigate these materials at a relatively high service temperature (58°C). From dynamic testing at temperatures ranging from -10°C to 80°C, the master curves of dynamic material functions (storage modulus, loss modulus, and loss tangent) were prepared at a reference temperature of 58°C. The relaxation and retardation spectra were calculated for all the materials, and the corresponding (compressive) compliance, D(t) (linear viscoelastic), was also determined from the retardation spectrum. It was shown that D(t) can be effectively approximated from the magnitude of the complex compliance by transforming the domain of the reduced frequencies to the time domain. From the wheel tracking test performed at 58°C, th
