Research on Rubber/SBS Modified Asphalt by MSCR Test
Multiple stress creep recovery test (MSCR) as an effective evalution mothed for polymer modified asphalt was studied newly, and was formed a new ASTM standard. In this article, SBS modified asphalt, rubber asphalt, and rubber/SBS composite modified asphalt were taken a multiple stress creep recovery test (MSCR) through the dynamic shear rheometer (DSR), value of Jnr and Jnr-diff from MSCR test of different modified asphalt were studied according to ASTM D7405-08. The results showed the rubber / SBS modified asphalt had a lower Jnr compared with the other two, which indicating that it had an obvious advantage on high temperature deformation resistancing. Furthermore, low Jnr-diff value was related with lower dependence on the shear stress. made it applicable to conditions such as high temperature and overload or long steep road construction; MSCR test also provides a reasonable basis for choosing modified asphalt in such geological and climate conditions.
