| 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. |
