Study on Cement-Treated Yangtze Hydraulic Sand Mixed with Expanded Polystyrenes (EPS) Beads as Backfill Material in Highway Embankments
The mechanical characteristics of the lightweight fill using hydraulic sand mixing with expanded polystyrene (EPS) beads were investigated in this paper. Unconfined compression tests, CBR tests and tri-axial shear tests were performed for the presented lightweight fill. The numerical study using a simple model in PLAXIS manual was conducted to verify the performance of embankments filling with the proposed material. Compared with the general lime stabilized soil embankments, the proposed material can significantly reduce the settlement which is beneficial for the highway serviceability. The research results show that the mixing lightweight soil is adequate to be used as the filling material of highway embankments to decrease the damage potential of the bridge-head jumping and to control the post-construction settlement. It is a new kind of filling conception for highway embankment projects.
