ABSTRACT
Earthquakes often induce differential settlement between bridges and their approach embankments. Consequently, vehicles cannot pass the step-wise settlement. The confined-reinforced earth (CRE) method, has been proposed to make it possible for vehicles, especially emergency vehicles to pass road surfaces roughened. In this study, the effect of the length of geogrids on the behavior of the CRE subjected to differential settlement was investigated. The results showed that the CRE surface settlement distribution and tensile strain along the geogrids were significantly affected by the geogrid length. CRE with long geogrids is recommended to use in practice.
