| Abstract: | New method to evaluate the high temperature stability of asphalt mixtures is studied on the basis of existing wheel tracking test.The limitation of current method to evaluate the high temperature stability of asphalt mixtures is analyzed.And then dynamic stability is applied to estimate error source.Whole process dynamic stability(DSWP)is brought forward to evaluate the high temperature stability of asphalt mixtures.Wheel tracking tests of different graduations(AC-13,AC-20,SMA-13,SMA-20 and ATB-25) are done... |
