    Abstract
  • The index system of structure design was proposed according to the fatigue failure type and rutting failure type of steel bridge deck, and it was classified into two types, one is fatigue index, another is rutting index. The conversion method of axle-load was proposed based on its fatigue and rutting equivalent ruks. The conversion formulas of steel bridge deck were proposed based on fatigue equivalent ruks. The conversion exponents and coefficients of other axle-type and wheel-type of the formulas were computed according to fatigue tests and mechanical analysis. Computation results show that the conversion exponent is (4.35) for guss asphalt concrete pavement, the conversion exponent is 5.30 for modified asphalt SMA qavement, the conversion exponent is 6.25 for epoxy asphalt concrete pavement. The conversion formulas can be applied to design or check the computation of steel bridge deck pavement, and its conversion results are precise and feasible.
