The Study of Rheological Behavior about High-Modulus Modified Asphalt
Research shows that rheological property of asphalt relates directly to pavement property. To get a grip on the influence of different factors on rheological property of high modulus asphalt, this paper makes a systematic study of different temperatures, loading frequency, strain 70# base asphalt and rheological property of high modulus asphalt by the method of DSR measurement, and compared their anti-fatigue performance. The experiment’s results shows that high-modules asphalt has a low sensitivity of temperature. Compare with the base asphalt, the high-modules modified asphalt’s G*/sinδ will have a slower decrease rapid under the condition of temperature increase. Both asphalt’s G*/sinδ would decrease with the decrease of load frequency, high-modules asphalt has a higher G*/sinδ than base asphalt especially at the high temperature and low frequency.
