To cope with the fatigue cracking occurred to the asphalt mixture on steel deck pavement, it is put forward that the fatigue life of asphalt mixture can be improved by reducing the failure energy of each hysteresis loop of asphalt mixture according to the cumulative dissipated energy and hysteresis loop theory in the principle of viscoelasticity for asphalt mixture. Based on this principle, a kind of modified asphalt with high elasticity was developed, and its high and low temperature performances and fatigue performances were also tested. The result shows that (1) low temperature deformability of the high-elastic modified asphalt mixture has remarkably improved and low temperature bending strain of girder at 10 ° C is above 10000 μ ε ; (2) the fatigue life of modified asphalt mixture with high elasticity has greatly improved by 4-point bending beam test compared with common modified asphalt mixture. The fatigue life at 1000 μ ε ; deformability is about 1.9 million times which is about 20 times longer than that of ordinary asphalt mixture.
