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.

Sbs Modified Asphalt

A type of high modulus asphalt was prepared by mixing modifier into SBS modified asphalt and used for confecting HMAC-16 high modulus asphalt concrete with finished product of modified asphalt from Liaohe oil field. This paper investigates pavement performance of high modulus asphalt concrete and its practical application in bridge pavement. Results obtained by application in practical project show that the high modulus asphalt concrete is provided with outstanding high-and-low temperature performance and water damage resistance which are suitable for bridge pavement.
