| Abstract: | Through DSR test to A-30 hard asphalt and A-70 asp ha lt,the high-temperature performance of A-30 hard asphalt was analyzed;throug h single axle creep test and rutting test to four kinds of asphalt mixture,the high-temperature performance of A-30 hard asphalt mixture was analyzed.From t hat we can draw a conclusion that the hard asphalt mixture which can enhance the high temperature stability of pavement structure is suitable for the paving of base layer. |
| Keywords: | DSR test hard asphalt hard asphalt mixture single axle creep test rutting test high-temperature Performance |
