Compared with ordinary soil subgrade, the maximum settlement deformation and lateral deformation of FLS subgrade decrease by 68% and 91%. This indicates that using FLS as filling material can significantly control the settlement deformation and lateral deformation of subgrade, and has good engineering application value and feasibility.
