Fill Material at Integral End Bents
| 项目名称： | Fill Material at Integral End Bents |
| 摘要： | KYTC has adopted a modified procedure for designing and constructing approach fills at bridges with integral end bents at selected sites. The modified approach includes geosynthetic reinforced soil (GRS) backfill. Polystyrene foam (Geofoam) is placed between the GRS backfill and the bridge end. Based on displacement measurements obtained at two sites, this procedure has reduced settlement at bridge approaches. Based on comments from district construction staff there appears to be a need to modify the design where the geofoam and overlying pavement meet. There is also concern about the geofoam�s expense. Alternative materials dimensions and location, which would not be damaged by the bridge movement, should be explored to make the modified approach easier and cheaper to construct and reduce settlement further. |
