EarthTrac™ MSE systems have been used extensively for bridge abutment applications including both “true” abutments, where the bridge beams rest on a shallow spread footing (bridge bankseat) at the top of the MSE wall, and mixed abutments, where the bankseat is supported by separate supports (usually piles) located within the MSE mass. True abutments completely eliminate the “bump at the end of the bridge” and the maintenance costs and disruptions associated with it. As authorities trend towards an increasing use of integral abutments, the strength and flexibility of MSE abutments becomes even more attractive. Have a look at some projects featuring bridge abutments employing EarthTec’s technology.
EarthTec’s systems are ideally suited to use in bridge abutment applications.
EarthTrac HA™ employs ribbed steel strips which allow very high loads to be carried at low strains and without long term creep deformation.
EarthTrac PET™ and EarthTrac Ultra ™ geosynthetic straps can be skewed around bridge seat support piles, eliminating a key disadvantage of geogrid based geosynthetic MSE walls.
EarthTec’s EcoForm MSE system provides a reliable low cost option for abutments to temporary bridges.
