博士 / 國立中央大學 / 土木工程研究所 / 99 / The steel bridges are located on traffic artery, it is usually affected by traffic impact; hence, the pavement of the steel deck on the bridge must provide excellent efficiency to prolong the service life of pavement. This study utilized mechanical calculation method and finite element method ABAQUS software to analyze the mechanical response of different flexible pavement material combinations on steel deck. Heavy vehicle load with high axle load and high tire pressure were considered, so as to know the reasons for steel deck pavement distress, and to define the arrangement principle for steel deck pavement and the combination of materials suitable for flexible pavement.
The results show that the fatigue damage of steel deck pavement coincides with traditional theory, the maximum principal tensile strain at the bottom of surface course is still the determination criterion, As for the priority of two fatigue damage modes of steel deck pavement, the first one was the crack from the bottom up at the bottom of surface course, secondly the longitudinal crack near the top (or including bottom) of surface course on ribs. The maximum compressive strain on the top of steel plate is the determination criterion of rutting damage, the major cause for rut is the surface course under compressive strain in the wheel load position. The suitable material for steel deck one-course pavement is full depth GUSS asphalt concrete; the suitable combination for steel deck two-course pavement is modified asphalt concrete on top and GUSS asphalt concrete at bottom.
