Abstract

In order to investigate the physical and high/low-temperature rheological properties of asphalt modified with calcium sulfate whisker(CSW) and styrene-butadiene-styrene block copolymer(SBS),three major indicators,dynamic shear rheology(DSR),and bending beam rheology(BBR) tests were conducted to investigate the effects of different CSW contents on this composite modified asphalt.Meanwhile,CSW-modified asphalt was set as a control group.The results showed that with the increase of CSW content,the temperature sensitivity and high-temperature performance of CSW-modified asphalt were increased while the low-temperature performance decreased.The penetration index(PI),rutting factor G*/sin δ,creep modulus S,and creep rate m of the CSW-modified asphalt with 10% CSW were -0.83,27.70 kPa,368 MPa,and 0.271,respectively.The temperature sensitivity and high/low-temperature rheological properties of CSW/SBS modified asphalt were significantly improved compared with those of CSW-modified asphalt.PI,G*/sin δ,and m were improved by 147.0%,82.3%,and 7.4%,respectively.But S was decreased by 19.5%.At the same time,the high-temperature and low-temperature PG of the CSW/SBS modified asphalt with 8% CSW were 82 ℃ and -18 ℃,respectively,which were elevated by two and one levels,respectively.Therefore,the high-temperature performance and temperature sensitivity of asphalt binders could be significantly improved by the addition of CSW,but the low-temperature performance was slightly decreased.The low-temperature performance of asphalt binders could be maintained while CSW was composited with SBS.
