abstract = "The aging existing in use and construction of bituminous pavement will directly resulting in shortening of the pavement's service life. It is provide the theoretical basis of the design and construction of the SBS modified asphalt mixture to analyze the influence of aging to the rheological property of SBS modified asphalt under high temperature. The testing for the rheological property of three kinds SBS modified asphalt under high temperature has been finished before and after the aging in construction by Brookfield DV II+ type of rotation viscometer. The results indicated that viscosity will be increased and the sensitivity of SBS modified asphalt to viscosity will also be lowered along with increase of aging degree. The testing for the rheological property of three kinds of SBS modified asphalt has been finished before and after aging in usage period by the dynamic shear rheometer (DSR). The results shown that G * will be continually increased along with increase of aging degree and this is consistent with change of base asphalt. And this shown that the increase of G* can only come down to oxidation and aging of base asphalt contained in the modified asphalt and also, asphaltene in SBS modified asphalt will be changing in the mode same with that of base asphalt.",
