Abstract: A sensitive method was used to measure the content of styrene-butadiene rubber(SBR) in modified asphalt by HPLC. The temperature was set at 30 ℃ and a wavelength of 222 nm was used for the detector. A mobile phase of hexane, acetonitrile and THF with equal proportion was used. The RSD of this method is 1.5%, and a linear equation of y=800.94x+579.03 with a correlation coefficient of r=0.9998 was obtained.

Key words: HPLC, Gel column, Modified asphalt, SBR
