A STUDY OF THE STRAIN BEHAVIOR OF ASPHALT PAVEMENT ON BRIDGE BY VISCOELASTIC ANALYSIS

線形粘弾性解析による橋面舗装のひずみ挙動に関する研究

In asphalt pavement on bridge, there are various damages. Many damages are reported on pavement on the steel deck plate. However, the strain behavior of the asphalt pavement of a bridge is not fully grasped. So, viscoelastic analysis was performed by using FEM (finite element method) simulating behaviors of bridge deck and pavement. The results indicated that the strain behavior of pavement on earthwork and concrete slab was not changed by difference of loading position and view point and so on. On the other hand, it is cleared strain behavior of pavement on steel deck was changed complicatedly because of complexity of the structure of steel deck. It is thought this leads to the complicated destruction of pavement on steel deck and the results of this paper is used for preventive methods against damage and design method of pavement in expressway.　橋梁上のアスファルト舗装では様々な損傷が発生しており，特に鋼床版舗装での損傷が多い．しかし，交通荷重載荷時の橋梁上のアスファルト舗装の挙動は十分に把握されているとはいえない．筆者らはこれまで，鋼床版舗装を模擬したアスファルト混合物と鋼板との複合供試体での載荷試験の結果を，線形粘弾性解析を用いて再現した．そして線形弾性解析では表現できない鋼床版舗装特有の挙動を再現することができた．本研究では，実路（実橋）モデルの線形粘弾性解析を実施し，床版構造などアスファルト舗装下面の構造の違いによる舗装体の挙動を検討した．その結果，コンクリート床版，鋼床版，土工部では交通荷重載荷時の舗装体の挙動がそれぞれ大きく異なっており，橋梁上のアスファルト舗装は土工部とは異なる損傷発生原因を有していることが示唆された．
